Message | WEB-CGI fom.cgi access |
Summary | This event is generated when an attempt is made to access fom.cgi on an internal web server. This may indicate an attempt to exploit a cross-site scripting vulnerability in Faq-O-Matic.
|
Impact | Arbitrary code execution, possible session hijack.
|
Detailed Information | Faq-O-Matic is a CGI-based system that automates FAQ maintenance on a web server. Versions 2.712 and lower contain a cross-site scripting vulnerability where an attacker can craft a URL with malicious code in the "cmd" argument. If a legitimate user activates the URL, malicious code may be executed on the client computer with the security context of the web server.
|
Affected Systems | Systems running or accessing Faq-O-Matic version 2.712 or lower.
|
Attack Scenarios | An attacker crafts a URL that, when activated by a legitimate user, obtains the session cookie. This can allow the attacker to pose as the user for the duration of the session.
|
Ease of Attack | Simple. A proof of concept exists.
|
Corrective Action | Upgrade to Faq-O-Matic version 2.713 or higher. Upgrades are available at http://faqomatic.sourceforge.net.
