Security readout for executives and security teams

CVE-2017-3839 is an XML External Entity issue in the Cisco Secure Access Control System web interface. An unauthenticated remote attacker could read some information stored on an affected system. Cisco identifies release 5.8(2.5) as affected. Available source data does not provide CVSS details or confirm active exploitation. Exposure is most likely where Cisco Secure Access Control System 5.8(2.5) is deployed and its web UI is reachable by untrusted networks. Systems used for access control may contain sensitive operational or identity-related information, so even partial read access deserves prompt validation. Medium priority unless ACS management interfaces are exposed externally or the system stores highly sensitive access-control data. The main business risk is unauthorized information disclosure from an identity and network access platform. Confirm exposure and follow Cisco guidance promptly. Mitigation focus: Review Cisco advisory cisco-sa-20170215-acs1 for vendor remediation guidance.; Inventory Cisco ACS deployments and identify any 5.8(2.5) systems.; Restrict ACS web UI access to trusted administrative networks..
