Add: krb5 kerberos credential

[nichtsfrei]

To support krb5 a new credential service is required to get the realm, as well as kdc in addition to username and password.

This adds:

<credentials>
 <credential type="up" service="krb5">
   <username>scanuser</username>
   <password>mypass</password>
   <realm>myrealm</realm>
   <kdc>mykdc</kdc>
 </credential>
</credentials>

Testing

To test create a test feed with the described nasl scripts. When you created the scripts run

sha256sum * > sha256sums

within the feed dir. Afterwards change the openvas.conf to the feed dir and disable the signature check.

For reference this is the openvas.conf that I used:

> openvas -s

max_checks = 10
optimize_test = yes
auto_enable_dependencies = yes

cgi_path = /cgi-bin:/scripts
max_hosts = 30

config_file = /etc/openvas/openvas.conf
test_alive_wait_timeout = 3
vendor_version =
safe_checks = yes
scanner_plugins_timeout = 36000
include_folders = /workspaces/greenbone/ospd-krb5-feed
plugins_timeout = 320

expand_vhosts = yes
test_alive_hosts_only = yes
db_address = /run/redis/redis.sock
openvasd_server = http://localhost:6969
unscanned_closed_udp = yes

When all this is done send the xmls:

stdlib 1.19.8 (golang) pkg:golang/stdlib@1.19.8 Affected range <1.21.11 Fixed version 1.21.11 EPSS Score 0.06% EPSS Percentile 29th percentile Description The various Is methods (IsPrivate, IsLoopback, etc) did not work as expected for IPv4-mapped IPv6 addresses, returning false for addresses which would return true in their traditional IPv4 forms. Affected range <1.19.9 Fixed version 1.19.9 EPSS Score 0.25% EPSS Percentile 65th percentile Description Not all valid JavaScript whitespace characters are considered to be whitespace. Templates containing whitespace characters outside of the character set "\t\n\f\r\u0020\u2028\u2029" in JavaScript contexts that also contain actions may not be properly sanitized during execution. Affected range <1.19.10 Fixed version 1.19.10 EPSS Score 0.09% EPSS Percentile 40th percentile Description On Unix platforms, the Go runtime does not behave differently when a binary is run with the setuid/setgid bits. This can be dangerous in certain cases, such as when dumping memory state, or assuming the status of standard i/o file descriptors. If a setuid/setgid binary is executed with standard I/O file descriptors closed, opening any files can result in unexpected content being read or written with elevated privileges. Similarly, if a setuid/setgid program is terminated, either via panic or signal, it may leak the contents of its registers. Affected range <1.22.7 Fixed version 1.22.7 EPSS Score 0.04% EPSS Percentile 17th percentile Description Calling Parse on a "// +build" build tag line with deeply nested expressions can cause a panic due to stack exhaustion. Affected range <1.22.7 Fixed version 1.22.7 EPSS Score 0.04% EPSS Percentile 17th percentile Description Calling Decoder.Decode on a message which contains deeply nested structures can cause a panic due to stack exhaustion. This is a follow-up to CVE-2022-30635. Affected range <1.21.12 Fixed version 1.21.12 EPSS Score 0.04% EPSS Percentile 17th percentile Description The net/http HTTP/1.1 client mishandled the case where a server responds to a request with an "Expect: 100-continue" header with a non-informational (200 or higher) status. This mishandling could leave a client connection in an invalid state, where the next request sent on the connection will fail. An attacker sending a request to a net/http/httputil.ReverseProxy proxy can exploit this mishandling to cause a denial of service by sending "Expect: 100-continue" requests which elicit a non-informational response from the backend. Each such request leaves the proxy with an invalid connection, and causes one subsequent request using that connection to fail. Affected range <1.21.8 Fixed version 1.21.8 EPSS Score 0.04% EPSS Percentile 12th percentile Description The ParseAddressList function incorrectly handles comments (text within parentheses) within display names. Since this is a misalignment with conforming address parsers, it can result in different trust decisions being made by programs using different parsers. Affected range <1.21.9 Fixed version 1.21.9 EPSS Score 0.04% EPSS Percentile 15th percentile Description An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no memory is allocated to store the excess headers, but they are still parsed. This permits an attacker to cause an HTTP/2 endpoint to read arbitrary amounts of header data, all associated with a request which is going to be rejected. These headers can include Huffman-encoded data which is significantly more expensive for the receiver to decode than for an attacker to send. The fix sets a limit on the amount of excess header frames we will process before closing a connection. Affected range <1.20.0 Fixed version 1.20.0 EPSS Score 0.08% EPSS Percentile 36th percentile Description Before Go 1.20, the RSA based TLS key exchanges used the math/big library, which is not constant time. RSA blinding was applied to prevent timing attacks, but analysis shows this may not have been fully effective. In particular it appears as if the removal of PKCS#1 padding may leak timing information, which in turn could be used to recover session key bits. In Go 1.20, the crypto/tls library switched to a fully constant time RSA implementation, which we do not believe exhibits any timing side channels. Affected range <1.20.11 Fixed version 1.20.11 EPSS Score 0.17% EPSS Percentile 55th percentile Description The filepath package does not recognize paths with a ??\ prefix as special. On Windows, a path beginning with ??\ is a Root Local Device path equivalent to a path beginning with \?. Paths with a ??\ prefix may be used to access arbitrary locations on the system. For example, the path ??\c:\x is equivalent to the more common path c:\x. Before fix, Clean could convert a rooted path such as \a..??\b into the root local device path ??\b. Clean will now convert this to .??\b. Similarly, Join(, ??, b) could convert a seemingly innocent sequence of path elements into the root local device path ??\b. Join will now convert this to .??\b. In addition, with fix, IsAbs now correctly reports paths beginning with ??\ as absolute, and VolumeName correctly reports the ??\ prefix as a volume name. UPDATE: Go 1.20.11 and Go 1.21.4 inadvertently changed the definition of the volume name in Windows paths starting with ?, resulting in filepath.Clean(?\c:) returning ?\c: rather than ?\c:\ (among other effects). The previous behavior has been restored. Affected range <1.20.10 Fixed version 1.20.10 EPSS Score 83.78% EPSS Percentile 99th percentile Description A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive server resource consumption. While the total number of requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create a new request while the existing one is still executing. With the fix applied, HTTP/2 servers now bound the number of simultaneously executing handler goroutines to the stream concurrency limit (MaxConcurrentStreams). New requests arriving when at the limit (which can only happen after the client has reset an existing, in-flight request) will be queued until a handler exits. If the request queue grows too large, the server will terminate the connection. This issue is also fixed in golang.org/x/net/http2 for users manually configuring HTTP/2. The default stream concurrency limit is 250 streams (requests) per HTTP/2 connection. This value may be adjusted using the golang.org/x/net/http2 package; see the Server.MaxConcurrentStreams setting and the ConfigureServer function. Affected range <1.20.10 Fixed version 1.20.10 EPSS Score 0.36% EPSS Percentile 73rd percentile Description A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive server resource consumption.

This is a follow-up to CVE-2022-30635. Affected range <1.19.9 Fixed version 1.19.9 EPSS Score 0.14% EPSS Percentile 52nd percentile Description Templates containing actions in unquoted HTML attributes (e.g. "attr={{.}}") executed with empty input can result in output with unexpected results when parsed due to HTML normalization rules. This may allow injection of arbitrary attributes into tags. Affected range <1.19.9 Fixed version 1.19.9 EPSS Score 0.14% EPSS Percentile 52nd percentile Description Angle brackets (<>) are not considered dangerous characters when inserted into CSS contexts. Templates containing multiple actions separated by a '/' character can result in unexpectedly closing the CSS context and allowing for injection of unexpected HTML, if executed with untrusted input. Affected range <1.21.8 Fixed version 1.21.8 EPSS Score 0.04% EPSS Percentile 12th percentile Description When parsing a multipart form (either explicitly with Request.ParseMultipartForm or implicitly with Request.FormValue, Request.PostFormValue, or Request.FormFile), limits on the total size of the parsed form were not applied to the memory consumed while reading a single form line. This permits a maliciously crafted input containing very long lines to cause allocation of arbitrarily large amounts of memory, potentially leading to memory exhaustion. With fix, the ParseMultipartForm function now correctly limits the maximum size of form lines. Affected range <1.19.11 Fixed version 1.19.11 EPSS Score 0.14% EPSS Percentile 51st percentile Description The HTTP/1 client does not fully validate the contents of the Host header. A maliciously crafted Host header can inject additional headers or entire requests. With fix, the HTTP/1 client now refuses to send requests containing an invalid Request.Host or Request.URL.Host value. Affected range <1.20.8 Fixed version 1.20.8 EPSS Score 0.11% EPSS Percentile 46th percentile Description The html/template package does not apply the proper rules for handling occurrences of "<script", "<!--", and "</script" within JS literals in <script> contexts. This may cause the template parser to improperly consider script contexts to be terminated early, causing actions to be improperly escaped. This could be leveraged to perform an XSS attack. Affected range <1.20.8 Fixed version 1.20.8 EPSS Score 0.15% EPSS Percentile 53rd percentile Description The html/template package does not properly handle HTML-like "" comment tokens, nor hashbang "#!" comment tokens, in <script> contexts. This may cause the template parser to improperly interpret the contents of <script> contexts, causing actions to be improperly escaped. This may be leveraged to perform an XSS attack. Affected range <1.21.8 Fixed version 1.21.8 EPSS Score 0.04% EPSS Percentile 12th percentile Description Verifying a certificate chain which contains a certificate with an unknown public key algorithm will cause Certificate.Verify to panic. This affects all crypto/tls clients, and servers that set Config.ClientAuth to VerifyClientCertIfGiven or RequireAndVerifyClientCert. The default behavior is for TLS servers to not verify client certificates. Affected range <1.21.11 Fixed version 1.21.11 EPSS Score 0.04% EPSS Percentile 11th percentile Description The archive/zip package's handling of certain types of invalid zip files differs from the behavior of most zip implementations. This misalignment could be exploited to create an zip file with contents that vary depending on the implementation reading the file. The archive/zip package now rejects files containing these errors. Affected range <1.20.11 Fixed version 1.20.11 EPSS Score 0.08% EPSS Percentile 36th percentile Description On Windows, The IsLocal function does not correctly detect reserved device names in some cases. Reserved names followed by spaces, such as "COM1 ", and reserved names "COM" and "LPT" followed by superscript 1, 2, or 3, are incorrectly reported as local. With fix, IsLocal now correctly reports these names as non-local. Affected range <1.20.12 Fixed version 1.20.12 EPSS Score 0.06% EPSS Percentile 27th percentile Description A malicious HTTP sender can use chunk extensions to cause a receiver reading from a request or response body to read many more bytes from the network than are in the body. A malicious HTTP client can further exploit this to cause a server to automatically read a large amount of data (up to about 1GiB) when a handler fails to read the entire body of a request. Chunk extensions are a little-used HTTP feature which permit including additional metadata in a request or response body sent using the chunked encoding. The net/http chunked encoding reader discards this metadata. A sender can exploit this by inserting a large metadata segment with each byte transferred. The chunk reader now produces an error if the ratio of real body to encoded bytes grows too small. Affected range <1.19.12 Fixed version 1.19.12 EPSS Score 0.12% EPSS Percentile 48th percentile Description Extremely large RSA keys in certificate chains can cause a client/server to expend significant CPU time verifying signatures. With fix, the size of RSA keys transmitted during handshakes is restricted to <= 8192 bits. Based on a survey of publicly trusted RSA keys, there are currently only three certificates in circulation with keys larger than this, and all three appear to be test certificates that are not actively deployed. It is possible there are larger keys in use in private PKIs, but we target the web PKI, so causing breakage here in the interests of increasing the default safety of users of crypto/tls seems reasonable.

openssl 3.0.15-1~deb12u1 (deb) pkg:deb/debian/openssl@3.0.15-1~deb12u1?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=3.0.11-1~deb12u2 Fixed version Not Fixed EPSS Score 0.07% EPSS Percentile 31st percentile Description OpenSSL 0.9.8i on the Gaisler Research LEON3 SoC on the Xilinx Virtex-II Pro FPGA uses a Fixed Width Exponentiation (FWE) algorithm for certain signature calculations, and does not verify the signature before providing it to a caller, which makes it easier for physically proximate attackers to determine the private key via a modified supply voltage for the microprocessor, related to a "fault-based attack."

curl 7.88.1-10+deb12u8 (deb) pkg:deb/debian/curl@7.88.1-10%2Bdeb12u8?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=7.88.1-10+deb12u8 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 15th percentile Description libcurl skips the certificate verification for a QUIC connection under certain conditions, when built to use wolfSSL. If told to use an unknown/bad cipher or curve, the error path accidentally skips the verification and returns OK, thus ignoring any certificate problems.

gnupg2 2.2.40-1.1 (deb) pkg:deb/debian/gnupg2@2.2.40-1.1?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=2.2.40-1.1 Fixed version Not Fixed EPSS Score 0.05% EPSS Percentile 19th percentile Description GnuPG can be made to spin on a relatively small input by (for example) crafting a public key with thousands of signatures attached, compressed down to just a few KB.

shadow 1:4.13+dfsg1-1 (deb) pkg:deb/debian/shadow@1:4.13%2Bdfsg1-1?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=1:4.13+dfsg1-1 Fixed version Not Fixed EPSS Score 0.16% EPSS Percentile 53rd percentile Description initscripts in rPath Linux 1 sets insecure permissions for the /var/log/btmp file, which allows local users to obtain sensitive information regarding authentication attempts. NOTE: because sshd detects the insecure permissions and does not log certain events, this also prevents sshd from logging failed authentication attempts by remote attackers.

glib2.0 2.74.6-2+deb12u4 (deb) pkg:deb/debian/glib2.0@2.74.6-2%2Bdeb12u4?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=2.74.6-2+deb12u4 Fixed version Not Fixed EPSS Score 0.16% EPSS Percentile 53rd percentile Description GLib 2.31.8 and earlier, when the g_str_hash function is used, computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table. NOTE: this issue may be disputed by the vendor; the existence of the g_str_hash function is not a vulnerability in the library, because callers of g_hash_table_new and g_hash_table_new_full can specify an arbitrary hash function that is appropriate for the application.

net-snmp 5.9.3+dfsg-2 (deb) pkg:deb/debian/net-snmp@5.9.3%2Bdfsg-2?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=5.9.3+dfsg-2 Fixed version Not Fixed Description net-snmp 5.9.4 contains a memory leak vulnerability in /net-snmp/apps/snmpvacm.c.
