Discussion

Rsync Sanitize_path Function Module Path Escaping Vulnerability

If an rsync server is installed as a daemon with a read/write enabled module without using the 'chroot' option, it is possible that a remote attacker could read/write files outside of the configured module path. Rsync does not properly sanitize the paths when not running with chroot. The problem exists in the 'sanitize_path' function.

This could potentially be exploited to execute arbitrary code by corrupting or place arbitrary files on the system. Destruction of data could also result, possibly causing a denial of service condition. Other attacks could also occur, depending on the attacker's motives.
