Cisco: >> Unified Communications Manager Im And Presence Service >> 12.5(1)su8 Security Vulnerabilities
CVE-2026-20045
A vulnerability in Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Manager Session Management Edition (Unified CM SME), Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P), Cisco Unity Connection, and Cisco Webex Calling Dedicated Instance could allow an unauthenticated, remote attacker to execute arbitrary commands on the underlying operating system of an affected device.
This vulnerability is due to improper validation of user-supplied input in HTTP requests. An attacker could exploit this vulnerability by sending a sequence of crafted HTTP requests to the web-based management interface of an affected device. A successful exploit could allow the attacker to obtain user-level access to the underlying operating system and then elevate privileges to root.
Note: Cisco has assigned this security advisory a Security Impact Rating (SIR) of Critical rather than High as the score indicates. The reason is that exploitation of this vulnerability could result in an attacker elevating privileges to root.

A vulnerability in the CLI of multiple Cisco Unified Communications products could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system of an affected device as the root user.
This vulnerability is due to improper validation of user-supplied command arguments. An attacker could exploit this vulnerability by executing crafted commands on the CLI of an affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system of an affected device as the root user. To exploit this vulnerability, the attacker must have valid administrative credentials.

A vulnerability in the logging component of Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P) could allow an authenticated, remote attacker to view sensitive information in clear text on an affected system.
This vulnerability is due to the storage of unencrypted credentials in certain logs. An attacker could exploit this vulnerability by accessing the logs on an affected system and obtaining credentials that they may not normally have access to. A successful exploit could allow the attacker to access sensitive information from the device.

A vulnerability in the web-based management interface of Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Manager Session Management Edition (Unified CM SME), Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P), and Cisco Unity Connection could allow an authenticated, remote attacker to access sensitive data on an affected device. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request that contains directory traversal character sequences to an affected system. A successful exploit could allow the attacker to access sensitive files on the affected system.
