How the Exploit Works
The vulnerability resides in the OAuth2 implementation of Corezoid 6.6.0. Specifically, it involves an open redirect in the redirect_uri parameter. This open redirect allows an attacker to intercept authorization codes by redirecting the victim to a malicious site controlled by the attacker. Once the attacker has the authorization codes, they can gain unauthorized access to the victim’s account.
Conceptual Example Code
Consider the following conceptual HTTP request:
GET /authorize?response_type=code&client_id=CLIENT_ID&redirect_uri=https://malicious.example.com&state=STATE HTTP/1.1
Host: vulnerable.example.comIn this example, the attacker has manipulated the redirect_uri parameter to point to a site they control (malicious.example.com). When the victim clicks on this manipulated link, they are redirected to the attacker’s site, where the authorization code is intercepted.
Mitigation Guidance
Users of Corezoid 6.6.0 are advised to apply the vendor patch immediately to mitigate the vulnerability. If a patch is not immediately available, users can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation. These systems can detect and block malicious activity related to this vulnerability.
