CVE-2024-20352 [Medium] | Path Traversal in Emergency Responder

A vulnerability in Cisco Emergency Responder could allow an authenticated, remote attacker to conduct a directory traversal attack, which could allow the attacker to perform arbitrary actions on an affected device. This vulnerability is due to insufficient protections for the web UI of an affected system. An attacker could exploit this vulnerability by sending crafted requests to the web UI. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the affected user, such as accessing password or log files or uploading and deleting existing files from the system.
