Cross-site scripting (XSS) vulnerability in Squid Analysis Report Generator (Sarg) 2.2.4 allows remote attackers to inject arbitrary web script or HTML via a JavaScript onload event in the User-Agent header, which is not properly handled when displaying the Squid proxy log. NOTE: this issue exists because of an incomplete fix for CVE-2008-1168.
