RosarioSIS Stores Sensitive Data in a Mechanism without Access Control

High severity GitHub Reviewed Published May 19, 2023 to the GitHub Advisory Database • Updated Nov 10, 2023

Package

composer francoisjacquet/rosariosis (Composer)

Affected versions

< 11.0

Patched versions

11.0

Description

RosarioSIS prior to 11.0 allows anyone, regardless of authentication status, to download and view file attachments under the salaries module. In addition, the file names contain a date in a YYYY-MM-DD format and a random six-string digit, making enumerating file names with automated tools relatively easy. This could allow an attacker to gain access to sensitive salary information. The patch for version 11.0 adds microseconds to filenames to make them harder to guess.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
