9.8

CVSS v3.1

Official Description

A vulnerability in Cisco Unified Communications Domain Manager could allow an unauthenticated, remote attacker to bypass security protections, gain elevated privileges, and execute arbitrary code. The vulnerability is due to insecure key generation during application configuration. An attacker could exploit this vulnerability by using a known insecure key value to bypass security protections by sending arbitrary requests using the insecure key to a targeted application. An exploit could allow the attacker to execute arbitrary code. This vulnerability affects Cisco Unified Communications Domain Manager releases prior to 11.5(2). Cisco Bug IDs: CSCuv67964.

Technical Analysis

CVE-2018-0124 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
