A vulnerability in the fabric interconnect (FI) web management interface of the Cisco Unified Computing System could allow an unauthenticated, remote attacker to conduct cross-site request forgery (CSRF) attacks. The vulnerability occurs because the web interface relies on cookies to authenticate URL-based commands. An attacker could exploit this vulnerability by persuading the user to follow a malicious link or visit an attacker-controlled website while authenticated to the FI web management interface. A successful exploit could allow the attacker to perform various activities as the affected user. Cisco has confirmed the vulnerability in a security notice; however, software updates are not available. 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.
The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory.
