CVE-2020-27121 (GCVE-0-2020-27121)

Vulnerability from cvelistv5 – Published: 2020-11-06 18:15 – Updated: 2024-11-13 17:44

Title

Cisco Unified Communications Manager IM and Presence Service Denial of Service Vulnerability

Summary

A vulnerability in Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P) Software could allow an authenticated, remote attacker to cause the Cisco XCP Authentication Service on an affected device to restart, resulting in a denial of service (DoS) condition. The vulnerability is due to improper handling of login requests. An attacker could exploit this vulnerability by sending a crafted client login request to an affected device. A successful exploit could allow the attacker to cause a process to crash, resulting in a DoS condition for new login attempts. Users who are authenticated at the time of the attack would not be affected. There are workarounds that address this vulnerability.

Severity
