CVE-2022-37703

建议描述 在 Amanda 3.5.1 中，发现了一个信息泄露漏洞，位于 calcsize SUID 二进制文件中。攻击者可利用该漏洞判断 文件系统中的任意目录是否存在。该二进制文件将使用 opendir 以 root 身份直接执行而不检查路径，从而 允许攻击者提供任意路径。攻击者需要是 backup 用户才能运行 calcsize 二进制文件。 附加信息 PoC 非常简单，你只需像这样运行该二进制文件： ./calcsize MAHER dir1 -X directory 如果该二进制文件没有产生任何输出，则说明该目录存在。 如果不存在，它会像这样提示不可用：...
