Title: Computalynx CMail Web File Access Vulnerability
Severity: MODERATE
Description:
A vulnerability in Computalynx's CMail allows remote malicious users to steal local files.
Compulynx's CMail is a Win32 mail server program. One of its features is allowing users to access their email with a web browser via a built-in web server.
The web server fails to check whether requested files fall outside its document tree (by using ".." in the URL). Thus attackers can retrieve files in the same drives as that on which the software resides if they know or can get it's filename.
A number of buffer overflows in the processing of SMTP and POP commands also exist.
Affected Products:
- Computalynx CMail 2.3.0
