“An attacker could exploit this vulnerability by uploading arbitrary files to an affected system,” Cisco said in an advisory released Wednesday. “A successful exploit could allow the attacker to store malicious files on the system, execute arbitrary commands on the operating system, and elevate privileges to root.”
The flaw affects some versions of Cisco Unity Connection, but not Version 15.
12.5 and earlier (Fixed in version 12.5.1.19017-4)
14 (Fixed in version 14.0.1.14006-5)
Maxim Suslov, a security researcher, found and reported the bug. Cisco didn’t mention any evidence of the bug being used by attackers, but it’s recommended for users to update to a fixed version to reduce potential risks.
Cisco has fixed 11 medium-severity vulnerabilities in its software, along with the patch for CVE-2024-20272. The affected products include Identity Services Engine, WAP371 Wireless Access Point, ThousandEyes Enterprise Agent, and TelePresence Management Suite (TMS).
Cisco will not fix the command injection bug in WAP371 (CVE-2024-20287, CVSS score: 6.5) because the device reached end-of-life in June 2019. Cisco suggests customers migrate to the Cisco Business 240AC Access Point.
