Title: WebText User Profile PHP Code Injection Vulnerability

Severity: HIGH

Description:

WebText is a web application to send text messages; it is implemented in PHP.

The application is prone to an arbitrary PHP code-injection vulnerability because it fails to properly sanitize user-supplied input to the 'wt/users/[nick].php' script.

An attacker can exploit this issue to inject and execute arbitrary malicious PHP code in the context of the webserver process. This may facilitate a compromise of the application and the underlying system; other attacks are also possible.

WebText version 0.4.5.2 is vulnerable; other versions may also be affected.

Affected Products:

  • WebText WebText 0.4.5.2
