Updates are not available. Description A vulnerability in the Data Center Analytics Framework (DCAF) application could allow an unauthenticated, remote attacker to execute unwanted actions. The vulnerability is due to insufficient cross-site request forgery (CSRF) protection. An attacker could exploit this vulnerability by tricking the user of a web application into executing an adverse action. Cisco has confirmed the vulnerability; however, software updates are not available. Warning Indicators At the time this alert was first published, Cisco DCAF release 1.4 was vulnerable. Later releases of Cisco DCAF may also be vulnerable. IntelliShield Analysis To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the provided link. Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available. Vendor Announcements Cisco has released bug ID CSCun26807 for registered users, which contains additional details and an up-to-date list of affected product versions. Impact An unauthenticated, remote attacker could exploit this vulnerability to take unauthorized actions on behalf of a targeted user. A successful exploit could allow the attacker to conduct further attacks. Technical Information The vulnerability is due to insufficient validation of user-supplied input by the affected software. An attacker could exploit this vulnerability by convincing a user to follow a malicious link. A successful exploit could allow the attacker to submit arbitrary requests to the affected device via the web browser with the privileges of the user, which could be leveraged to conduct further attacks. Safeguards Administrators are advised to contact the vendor regarding future updates and releases. Users should verify that unsolicited links are safe to follow. For additional information about cross-site request forgery attacks and potential mitigation methods, see the Cisco Applied Mitigation Bulletin Understanding Cross-Site Request Forgery Threat Vectors.
