CVE-2026-20078: 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 a relative path traversal flaw due to improper input sanitization in the web management interface. An attacker with valid administrative credentials can exploit this by sending crafted HTTPS requests to download arbitrary files from the system. The CVSS 3.1 base score is 6.5, reflecting a medium severity with network attack vector, low attack complexity, and requiring privileges but no user interaction. The vulnerability affects numerous versions from 12.5(1) through 15SU3 and 14SU5. No official patch or remediation level has been published by Cisco as of the data available.
Potential Impact
Successful exploitation allows an authenticated attacker with administrative privileges to download arbitrary files from the affected Cisco Unity Connection system, potentially exposing sensitive information. The vulnerability does not impact system integrity or availability directly but compromises confidentiality. There are no known exploits in the wild reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the Cisco vendor advisory for current remediation guidance. Since the vulnerability requires valid administrative credentials, restricting administrative access and enforcing strong authentication controls may reduce risk. Monitor Cisco's official advisories for patches or updates addressing this issue.
