Cisco · Cisco Unified Communications Manager Im & Presence Service · CVE-2022-20800
**Name of the Vulnerable Software and Affected Versions**
Cisco Unified Communications Manager versions (affected versions not specified)
Cisco Unified Communications Manager Session Management Edition versions (affected versions not specified)
Cisco Unified Communications Manager IM & Presence Service versions (affected versions not specified)
Cisco Unity Connection versions (affected versions not specified)
**Description**
A vulnerability in the web-based management interface could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. This issue exists because the interface does not properly validate user-supplied input. An attacker could exploit this by persuading a user to click a crafted link, potentially allowing the execution of arbitrary script code in the context of the affected interface or access to sensitive browser-based information.
**Recommendations**
For Cisco Unified Communications Manager, update to a version that properly validates user-supplied input in the web-based management interface.
For Cisco Unified Communications Manager Session Management Edition, update to a version that properly validates user-supplied input in the web-based management interface.
For Cisco Unified Communications Manager IM & Presence Service, update to a version that properly validates user-supplied input in the web-based management interface.
For Cisco Unity Connection, update to a version that properly validates user-supplied input in the web-based management interface.
As a temporary workaround, consider restricting access to the web-based management interface until a patch is available.
