CVE-2006-2801


Description:
Some vulnerabilities have been reported in Unak-CMS, which can be exploited by malicious people to conduct cross-site scripting attacks and SQL injection attacks.

1) Input passed to the "u_a" and "u_s" parameters 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 to the "u_a" and "u_s" parameters is also not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

The vulnerabilities have been reported in version 1.5 RC2. Other versions may also be affected.

Solution:
Edit the source code to ensure that input is properly sanitised.

Filter malicious characters and character sequences in a web proxy with URL filtering capabilities.
