Some vulnerabilities have been discovered in GLinks, which can be exploited by malicious people to conduct SQL injection attacks and compromise a vulnerable system.
1) Input passed to the "cat" parameter in index.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
2) Input passed to the "abspath" parameter in includes/header.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local and remote resources.
Successful exploitation of this vulnerability requires that "register_globals" is enabled and "magic_quotes_gpc" is disabled.
These vulnerabilities are confirmed in version 2.1. Other versions may also be affected.
Solution: Edit the source code to ensure that input is properly sanitised and verified.
