Detailsinfo

A vulnerability was found in CIRCL Vulnerability-Lookup up to 2.17.x. It has been rated as problematic. Affected by this issue is an unknown functionality. The manipulation with an unknown input leads to a cross-site request forgery vulnerability. Using CWE to declare the problem leads to CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. Impacted is integrity. CVE summarizes:

Some endpoints in vulnerability-lookup that modified application state (e.g. changing database entries, user data, configurations, or other privileged actions) may have been accessible via HTTP GET requests without requiring a CSRF token. This flaw leaves the application vulnerable to Cross-Site Request Forgery (CSRF) attacks: an attacker who tricks a logged-in user into visiting a malicious website could cause the user’s browser to issue GET requests that perform unintended state-changing operations in the context of their authenticated session. Because the server would treat these GET requests as valid (since no CSRF protection or POST method enforcement was in place), the attacker could exploit this to escalate privileges, change settings, or carry out other unauthorized actions without needing the user’s explicit consent or awareness.  The fix ensures that all state-changing endpoints now require HTTP POST requests and include a valid CSRF token. This enforces that state changes cannot be triggered by arbitrary cross-site GET requests. This issue affects Vulnerability-Lookup: before 2.18.0.

The advisory is available at vulnerability.circl.lu. This vulnerability is handled as CVE-2025-42616 since 04/16/2025. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. Successful exploitation requires user interaction by the victim. The technical details are unknown and an exploit is not available.

Upgrading to version 2.18.0 eliminates this vulnerability.
