CVE-2022-20829
Cisco Adaptive Security Device Manager and Adaptive Security Appliance Software Client-side Arbitrary Code Execution Vulnerability
In short
A flaw in Cisco ASA firewalls allows an admin attacker to upload a malicious management interface (ASDM) that can trick users into running harmful code on their computers. This is critical because it compromises anyone who manages the firewall remotely.
Technical detail
Insufficient validation of ASDM image authenticity during installation on Cisco ASA devices enables an authenticated remote attacker with administrative privileges to upload a crafted ASDM package containing malicious code. When a targeted user accesses the compromised device via ASDM client, arbitrary code execution occurs with user privileges on the client machine. Exploitation requires admin access to the ASA device and targets ASDM users managing that specific device.
Summary generated and translated by AI from the official description.
A vulnerability in the packaging of Cisco Adaptive Security Device Manager (ASDM) images and the validation of those images by Cisco Adaptive Security Appliance (ASA) Software could allow an authenticated, remote attacker with administrative privileges to upload an ASDM image that contains malicious code to a device that is running Cisco ASA Software. This vulnerability is due to insufficient validation of the authenticity of an ASDM image during its installation on a device that is running Cisco ASA Software. An attacker could exploit this vulnerability by installing a crafted ASDM image on the device that is running Cisco ASA Software and then waiting for a targeted user to access that device using ASDM. A successful exploit could allow the attacker to execute arbitrary code on the machine of the targeted user with the privileges of that user on that machine. Notes: To successfully exploit this vulnerability, the attacker must have administrative privileges on the device that is running Cisco ASA Software. Potential targets are limited to users who manage the same device that is running Cisco ASA Software using ASDM. Cisco has released and will release software updates that address this vulnerability.
