Cisco PI/EPNM Web UI Path Traversal Enables Remote Authenticated Write
CVE-2022-20656 Published on November 15, 2024

Cisco Prime Infrastructure and Cisco Evolved Programmable Network Manager Path Traversal Vulnerability
A vulnerability in the web-based management interface of Cisco PI and Cisco EPNM could allow an authenticated, remote attacker to conduct a path traversal attack on an affected device. To exploit this vulnerability, the attacker must have valid credentials on the system. This vulnerability is due to insufficient input validation of the HTTPS URL by the web-based management interface. An attacker could exploit this vulnerability by sending a crafted request that contains directory traversal character sequences to an affected device. A successful exploit could allow the attacker to write arbitrary files to the host system. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
