SmodCMS is prone to a vulnerability that lets attackers upload arbitrary files because the application fails to adequately sanitize user-supplied input. An attacker can exploit this vulnerability to upload arbitrary code and run it in the context of the webserver process. This may facilitate unauthorized access or privilege escalation; other attacks are also possible. SmodCMS v.4.07 is affected; other or lowers versions may also be vulnerable as well.
