Cross-site scripting (XSS) vulnerability in the SIP implementation on the Cisco SPA8000 and SPA8800 before 6.1.11, SPA2102 and SPA3102 before 5.2.13, and SPA 500 series IP phones before 7.4.9 allows remote attackers to inject arbitrary web script or HTML via the FROM field of an INVITE message, aka Bug IDs CSCtr27277, CSCtr27256, CSCtr27274, and CSCtr14715.

Security readout for executives and security teams

Cisco small business voice adapters and SPA phones could mishandle caller identity data in SIP INVITE messages. A remote attacker could inject web script or HTML through the FROM field. Business impact depends on whether vulnerable voice devices remain deployed and reachable. Exposure is most likely in legacy Cisco SPA voice adapters or SPA 500 series IP phones still running affected firmware, especially where SIP traffic is accepted from untrusted networks or upstream providers. Treat this as a legacy-asset risk. It is not flagged as actively exploited in the provided evidence, but exposed or outdated voice equipment should be patched, isolated, or replaced during normal vulnerability remediation cycles. Mitigation focus: Upgrade affected Cisco SPA devices to the fixed firmware versions or later.; Review the Cisco alert for product-specific remediation guidance.; Restrict SIP traffic to trusted providers and internal voice infrastructure..
