CVE-2013-5540: The file-upload feature in Cisco Identity Services Engine (ISE) allows remote authenticated users to cause...

Security readout for executives and security teams

Cisco ISE had a file-upload issue where a logged-in remote user could upload many files and consume disk space. The reported business impact is denial of service: the administration interface can become unavailable. The bundle does not provide affected versions, CVSS scoring, or proof of active exploitation. Exposure is most relevant to Cisco ISE deployments where authenticated users can reach the affected file-upload function. The provided data does not identify exact versions, configurations, or whether non-admin accounts are sufficient. Treat as a service-availability risk for identity infrastructure. Prioritize review where Cisco ISE administration is reachable by many authenticated users or supports critical network access workflows. Mitigation focus: Review Cisco’s security notice for affected releases and official remediation.; Restrict ISE administration and upload access to trusted users and networks.; Monitor ISE disk usage and administration-interface availability..
