OpenCA contains a cross site request forgery (XSRF) vulnerability that may allow an attacker to leverage an administrator's creditials to exectue activities on the Certification Authority.
The OpenCA PKI Development Project is an open source out-of-the-box Certification Authority (CA). OpenCA includes various web forms for executing requests and other activities on the CA such as digital certificate issuance. A cross site request forgery (XSRF) vulnerability exists in the way OpenCA processes requests executed via various forms. By manipulating an administrator who is authenticated to the CA via a session cookie to follow a tag that contains CA commands, an attacker may be able to successfully execute the commands on the CA.
An authenticated user can be manipulated into executing activities on the CA - such as digital certificate issuance - without knowledge or consent.
This vulnerability has been addressed in Security Advisory AKLINK-SA-2008-001.
