CVE-2026-20081: Relative Path Traversal in Cisco Cisco Unity Connection
Multiple vulnerabilities in Cisco Unity Connection could allow an authenticated, remote attacker to download arbitrary files from an affected system. To exploit these vulnerabilities, the attacker must have valid administrative credentials. These vulnerabilities are due to improper sanitization of user input to the web-based management interface. An attacker could exploit these vulnerabilities by sending a crafted HTTPS request. A successful exploit could allow the attacker to download arbitrary files from an affected system.
AI Analysis
Technical Summary
This vulnerability in Cisco Unity Connection involves relative path traversal due to insufficient input sanitization in the web management interface. An attacker with valid administrative credentials can send crafted HTTPS requests to download arbitrary files from the system. The CVSS 3.1 base score is 6.5, reflecting network attack vector, low attack complexity, required privileges, no user interaction, and high confidentiality impact without integrity or availability impact. Affected versions span multiple releases from 12.5(1) through 15SU3 and 14SU5.
Potential Impact
Successful exploitation allows an attacker with administrative privileges to read arbitrary files on the affected system, potentially exposing sensitive information. The confidentiality impact is high, but integrity and availability are not affected. There are no reports of active exploitation in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vulnerability requires valid administrative credentials, limiting administrative access and monitoring for suspicious activity may reduce risk until an official fix is available.
