CVE-2013-5522: Cisco IOS on Catalyst 3750X switches has default Service Module credentials, which makes it easier for loca...

Security readout for executives and security teams

Cisco reported that some Catalyst 3750X switches had default Service Module credentials. A person with local access could use those credentials to gain privileges. The public bundle does not provide CVSS scoring, affected version details, or a specific fix, so urgency depends on whether these switches are present and locally accessible. Exposure is most likely where Cisco Catalyst 3750X switches remain deployed and Service Module access is available to local or administrative users. The bundle does not identify internet-exposed attack paths or specific affected IOS releases. Treat as a targeted legacy-network risk. Prioritize confirming whether Catalyst 3750X devices remain in production, then follow Cisco guidance. Business urgency rises if local access is broad, privileged network devices are unmanaged, or device inventories are incomplete. Mitigation focus: Review Cisco's advisory for supported remediation for CSCue92286.; Inventory Catalyst 3750X switches and identify Service Module use.; Follow Cisco guidance for handling default Service Module credentials..
