Description:
Multiple vulnerabilities have been reported in Easy Chat Server, allowing malicious people to cause a DoS (Denial of Service), conduct cross-site scripting attacks, and potentially compromise a vulnerable system.
1) A boundary error within the handling of usernames can be exploited to cause a buffer overflow via an overly long string (about 300 bytes) passed to the "username" parameter in "chat.ghp".
Example:
http://[victim]/chat.ghp?username=[long_string]&password=&room=1&sex=0
Successful exploitation may allow execution of arbitrary code.
2) It is reportedly possible to crash the application by logging into a room with a large number of users.
3) An input validation error within the handling of usernames can be exploited to execute arbitrary HTML or script code in a user's browser session in context of a vulnerable site by tricking the user into visiting a malicious website or click a specially crafted link.
Example:
http://[victim]/chat.ghp?username=">[code]&password=&room=1&sex=0
The vulnerabilities have been reported in version 1.2. Prior versions may also be affected.
