Title: Geeklog Multiple Cross Site Scripting Vulnerabilities
Severity: HIGH
Description:
Geeklog is freely available, open-source weblog software. It is written in PHP and will run on most Unix and Linux variants, as well as Microsoft Windows NT/2000. Geeklog is backended by MySQL.
Geeklog does not filter script code from URL parameters, making it prone to cross-site scripting attacks. Attacker-supplied script code may be included in a malicious link to the 'index.php' or 'comment.php' script. The attacker-supplied script code will be executed in the browser of a web user who visits this link, in the security context of the host running Geeklog. Such a link might be included in a HTML e-mail or on a malicious webpage.
This may enable a remote attacker to steal cookie-based authentication credentials from legitimate users of a host running Geeklog.
This issue has been reported to exist in Geeklog 1.3.5, earlier versions may also be susceptible to this issue.
Affected Products:
- Geeklog Geeklog 1.3.5
