Feb 26, 2021
- Cisco Unified Communications Manager (CallManager)
Known Affected Releases
10.5(2.10000.5) 11.5(1.10000.6) 12.0(1.10000.10) 12.5(1.10000.22)
Symptom: A vulnerability in the web-based interface of Cisco Unified Communications Manager and Cisco Unified Communications Manager Session Management Edition (SME) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based interface. The vulnerability is due to insufficient validation of user-supplied input by the web-based interface of the affected software. An attacker could exploit this vulnerability by persuading a user of the interface to click a maliciously crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.
