Discussion

ChronoEngine ChronoForms mosConfig_Absolute_Path Multiple Remote File Include Vulnerabilities

ChronoEngine ChronoForms component for Joomla! is prone to multiple remote file-include vulnerabilities because it fails to sufficiently sanitize user-supplied input.

An attacker can exploit these issues to execute malicious PHP code in the context of the webserver process. This may allow the attacker to compromise the application and the underlying system; other attacks are also possible.

These issues affect ChronoForms 2.3.5; other versions may also be vulnerable.
