8.8 · HIGHOverview
CVE-2022-20759 is a high-severity vulnerability affecting cisco secure_firewall_threat_defense. It was published on May 3, 2022 and has a CVSS 3.1 base score of 8.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
A vulnerability in the web services interface for remote access VPN features of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, but unprivileged, remote attacker to elevate privileges to level 15. This vulnerability is due to improper separation of authentication and authorization scopes. An attacker could exploit this vulnerability by sending crafted HTTPS messages to the web services interface of an affected device. A successful exploit could allow the attacker to gain privilege level 15 access to the web management interface of the device. This includes privilege level 15 access to the device using management tools like the Cisco Adaptive Security Device Manager (ASDM) or the Cisco Security Manager (CSM). Note: With Cisco FTD Software, the impact is lower than the CVSS score suggests because the affected web management interface allows for read access only.
Remediation
Check the references section for vendor advisories and patches from cisco. Update secure_firewall_threat_defense to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
