AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in the command-line interface (CLI) of Cisco Secure FTD Software. It allows an authenticated local attacker, who already has valid administrative credentials, to execute arbitrary commands on the underlying operating system with root privileges.
The root cause is insufficient input validation of user-supplied command arguments. By submitting specially crafted input to a specific CLI command, the attacker can exploit this flaw to run commands as the root user.
How can this vulnerability impact me? :
If exploited, this vulnerability could allow an attacker with administrative access to gain full control over the affected device's operating system by executing arbitrary commands as root.
- Compromise of system integrity and security.
- Potential unauthorized access to sensitive data.
- Disruption of device operations or network security functions.
