webERP is prone to an arbitrary-file-upload vulnerability because the application fails to adequately sanitize user-supplied input.

An attacker can exploit this issue 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.

webERP 4.0.1 is vulnerable; other versions may also be affected.
