Deskripsi (NVD)

An issue was discovered in CommentsService.ashx in OnyakTech Comments Pro 3.8. An attacker can download a copy of the installer, decompile it, and discover a hardcoded IV used to encrypt the username and userid in the comment POST request. Additionally, the attacker can decrypt the encrypted encryption key (sent as a parameter in the comment form request) by setting this encrypted value as the username, which will appear on the comment page in its decrypted form. Using these two values (combined with the encryption functionality discovered in the decompiled installer), the attacker can encrypt another user's ID and username. These values can be used as part of the comment posting request in order to spoof the user.
