Log4j2 被爆出严重的 RCE 漏洞,至目前为止所有版本都存在该漏洞。对于 Minecraft 服务器来说,任何成员只需要向服务器发送带有特定内容的字符串,即可控制服务器执行攻击者想要的命令。(修复见 apache/logging-log4j2#608

由于 Minecraft 客户端允许在网络上共享世界,充当服务器的角色,此时也可能遭受类似的攻击。

该攻击是基于 Log4j2 中的 Message Pattern Lookup 功能,Minecraft 中似乎没有使用该功能,默认禁用它可以避免玩家在使用客户端开服时遭受对应攻击。

Forge 似乎在使用这个功能,需要考虑更保守的策略。
