affiliate-toolkit – WordPress Affiliate Plugin <= 3.3.9 - Open Redirect via atkpout.php

3.4
URL Redirection to Untrusted Site ('Open Redirect')
CVE CVE-2023-45105
CVSS 3.4 (Low)
Publicly Published October 6, 2023
Last Updated January 22, 2024
Researcher minhtuanact

Description

The affiliate-toolkit – WordPress Affiliate Plugin is vulnerable to Open Redirect in versions up to, and including, 3.3.9. This is due to insufficient validation on the redirect url supplied via the 'url' parameter in atkpout.php. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action. Only sites that do not have a atkp-imagereceiver-key.php setup are vulnerable, as the attacker must calculate the md5 hash of the URL combined with the key from that file in order to successfully redirect victims. If atkp-imagereceiver-key.php is not present, the md5 hash of atkpout.php, which is publicly available, will be used, allowing redirection.
