DescriptionCVE.org

A vulnerability was found in Dromara MaxKey up to 4.1.7 and classified as critical. This issue affects the function Add of the file maxkey-webs\maxkey-web-mgt\src\main\java\org\dromara\maxkey\web\apps\contorller\SAML20DetailsController.java of the component Meta URL Handler. The manipulation of the argument post leads to server-side request forgery. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

AnalysisAI

Server-side request forgery (SSRF) in Dromara MaxKey up to 4.1.7 allows authenticated attackers to make internal network requests via the Meta URL handler. A public exploit exists, but exploitation requires low privileges and no user interaction. EPSS score is low (0.11%), indicating limited active exploitation risk.

Technical ContextAI

The vulnerability is a server-side request forgery (CWE-918) in the SAML20DetailsController.java file of MaxKey, an open-source single sign-on (SSO) system. The affected component is the Meta URL Handler, which processes user-supplied URLs without proper validation, enabling attackers to forge requests to internal systems. CPE data confirms all MaxKey versions up to 4.1.7 are affected.

RemediationAI

No vendor-released patch is available as the vendor did not respond. As a workaround, restrict access to the SAML metadata URL handler by implementing network-level controls (e.g., firewall rules to block outbound requests from the MaxKey server to internal networks) or disable the Meta URL feature if not required. Input validation should be added to sanitize URLs and prevent requests to private IP ranges. These mitigations may impact SSO functionality that relies on metadata imports.
