一分钟漏洞结论

影响对象

利用判断

尚无明确在野利用证据，仍需结合暴露面评估

建议动作

优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。

logrotate是一款系统日志管理软件。基于Debian GNU/Linux的logrotate默认配置使用根权限去处理目录中的文件（允许低权限用户对该文件执行写操作）。本地用户可以利用logrotate支持不可信路径的缺陷，执行符号链接和硬链接攻击。该漏洞已经通过/var/log/postgresql/得到证实。

Vulnerability Description

The default configuration of logrotate on Debian GNU/Linux uses root privileges to process files in directories that permit non-root write access, which allows local users to conduct symlink and hard link attacks by leveraging logrotate's lack of support for untrusted directories, as demonstrated by /var/log/postgresql/.
