Cisco Discloses Zero-Day XSS Vulnerability in Prime Collaboration Deployment Software
Cisco Zero-Day Vulnerability in Prime Collaboration Deployment Software Discovered, Could Lead to Cross-Site Scripting Attacks
Cisco has disclosed a zero-day vulnerability in its Prime Collaboration Deployment (PCD) software that could be used for cross-site scripting attacks. The flaw was discovered in the web-based management interface of Cisco PCD 14 and earlier by a researcher at the NATO Cyber Security Centre.
The bug could allow unauthenticated attackers to launch remote cross-site scripting attacks, but user interaction is required. Cisco has warned that the vulnerability exists because the web-based management interface does not properly validate user-supplied input. The company is expected to release security updates to address the flaw next month, and no workarounds are currently available.

Workaround Involves Disabling Cisco Discovery Protocol
Although Cisco did not provide a workaround for this IP Phone zero-day vulnerability, the company advised admins to apply temporary mitigation measures, such as disabling the Cisco Discovery Protocol on affected devices supporting Link Layer Discovery Protocol (LLDP) as a fallback option.
Cisco has warned that this is not a trivial change and will require careful evaluation of potential impacts to devices.
