A vulnerability in the SSH subsystem of Cisco Adaptive Security Appliance (ASA) Software could allow an authenticated, remote attacker to execute operating system commands as root.
This vulnerability is due to insufficient validation of user input. An attacker could exploit this vulnerability by submitting crafted input when executing remote CLI commands over SSH. A successful exploit could allow the attacker to execute commands on the underlying operating system with root-level privileges. An attacker with limited user privileges could use this vulnerability to gain complete control over the system.

Detection & IOCsextracted from sources · hover to see the quote
- →Check for CiscoSSH stack being enabled on ASA — this is a prerequisite for CVE-2024-20329 to be exploitable; disabling it mitigates the vulnerability ↗
- →Apply the workaround command 'no ssh stack ciscossh' on affected ASA devices to disable the vulnerable CiscoSSH stack; note this will terminate active SSH sessions ↗
- →Monitor ASA SSH session logs for unusual or abnormal events that may indicate exploitation attempts via crafted remote CLI commands ↗
- →Track Cisco bug ID CSCwe93558 for patch and further technical details related to CVE-2024-20329 ↗
- ·Vulnerability is only exploitable when the CiscoSSH stack is enabled AND SSH access is permitted on at least one interface of the ASA device ↗
- ·Exploitation requires an authenticated attacker — unauthenticated exploitation is not possible; however, even a low-privileged user can leverage this to gain root ↗
- ·No active in-the-wild exploitation of CVE-2024-20329 had been observed at time of advisory publication ↗
