Summary
A vulnerability in the CLI of Cisco Secure Firewall Adaptive Security Appliance 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 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.
Details
| Severity | Base Score | CVE |
|---|---|---|
| HIGH | 7.2 | CVE-2026-20062 |
Exploitation
To exploit this vulnerability, an attacker must have valid administrative credentials for a non-admin context. The attacker can issue crafted SCP copy commands to read, create, or overwrite sensitive files belonging to another context. However, the attacker cannot list or enumerate files from another context and must know the exact file path, which increases the complexity of a successful attack.
Affected Products
- Cisco Secure Firewall Adaptive Security Appliance: Vulnerable in multiple context mode due to improper access controls for SCP operations.
Mitigation
To mitigate this vulnerability, ensure that proper access controls are in place for SCP operations and limit administrative privileges to necessary contexts only. Regularly review and update security configurations to prevent unauthorized access.
