Detailsinfo

A vulnerability was found in Admidio up to 5.0.9 and classified as problematic. This issue affects some unknown processing of the file modules/sso/keys.php of the component SSO Key Management. 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. The summary by CVE is:

Admidio is an open-source user management solution. Prior to version 5.0.10, the sensitive `mode=export` action in `modules/sso/keys.php` exports a PKCS#12 bundle containing the configured private key and certificate, but the CSRF validation line is commented out. A forged cross-site POST from an administrator session can therefore trigger private key export without a valid form token. Version 5.0.10 contains a fix.
