Yak! Chat Client FTP server is reported prone to a remote directory traversal vulnerability. This issue presents itself due to insufficient sanitization of user-supplied data.

This issue can ultimately allow an attacker to compromise a computer by placing malicious files on the system and executing these files through other means.

Yak! 2.1.2 and prior versions are reported vulnerable to this issue.

Exploit Public

- 漏洞描述

Yak contains a flaw that allows a remote attacker to write files outside of its FTP upload directory (which by default is the system's temporary directory). The issue is due to the program not properly sanitizing user input, specifically traversal style attacks (../../) supplied via the PUT method.
