Detailsinfo

A vulnerability was found in Cisco Secure Firewall Adaptive Security Appliance Software (version unknown) and classified as problematic. Affected by this issue is an unknown function of the component CLI. The manipulation with an unknown input leads to a incorrect execution-assigned permissions vulnerability. Using CWE to declare the problem leads to CWE-279. While it is executing, the product sets the permissions of an object in a way that violates the intended permissions that have been specified by the user. Impacted is confidentiality, integrity, and availability. CVE summarizes:

A vulnerability in the CLI of Cisco Secure Firewall Adaptive Security Appliance (ASA) Software in multiple context mode could allow an authenticated, local attacker with administrative privileges in one context to copy files to or from another context, including configuration files. This vulnerability is due to improper access controls for Secure Copy Protocol (SCP) operations when the CiscoSSH stack is enabled. An attacker could exploit this vulnerability by authenticating to a non-admin context of the device and issuing crafted SCP copy commands in that non-admin context. A successful exploit could allow the attacker to read, create, or overwrite sensitive files that belong to another context, including the admin and system contexts. The attacker cannot directly impact the availability of services pertaining to other contexts. To exploit this vulnerability, the attacker must have valid administrative credentials for a non-admin context. Note: An attacker cannot list or enumerate files from another context and would need to know the exact file path, which increases the complexity of a successful attack.

The advisory is available at sec.cloudapps.cisco.com. This vulnerability is handled as CVE-2026-20062 since 10/08/2025. The exploitation is known to be difficult. Local access is required to approach this attack. Additional levels of successful authentication are required for exploitation. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 03/04/2026). This vulnerability is assigned to T1222 by the MITRE ATT&CK project.
