A vulnerability in the CLI of Cisco Secure FTD Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system as root. To exploit this vulnerability, the attacker must have valid administrative credentials on an affected device. This vulnerability is due to insufficient input validation of user-supplied command arguments. An attacker could exploit this vulnerability by submitting crafted input for a specific CLI command. A successful exploit could allow the attacker to execute commands on the underlying operating system as root.
The severity level of this vulnerability is classified as medium, with a CVSS score of 6. The attack vector is local, requiring high privileges, but no user interaction is necessary. Risk to organizations includes potential unauthorized access and manipulation of system configurations.
Currently, the vulnerability status is awaiting analysis, and there are no known exploits or public proofs of concept available. Organizations should prioritize patching immediately to mitigate potential risks associated with this vulnerability.
Monitoring for any updates from Cisco regarding this vulnerability is essential, as well as reviewing administrative access controls to limit exposure.
Vulnerability Details
The vulnerability is attributed to insufficient input validation of command arguments in the Cisco Secure FTD Software CLI. The vulnerability is classified under CWE-88.
Technical Analysis
The root cause of the vulnerability is a failure to validate user input adequately, allowing for command injection. The attack vector is local, meaning that an attacker must have local access to the device and possesses high privileges. The attack complexity is low, as no user interaction is required to exploit this vulnerability. The potential impacts include high confidentiality and integrity impact, as an attacker could execute arbitrary commands with root privileges.
Risk & Impact Analysis
The risk to organizations includes unauthorized access to sensitive system operations, potentially leading to data loss or system compromise. The vulnerability's medium severity indicates that while it may not be critical, it still poses a significant risk that should not be ignored. Organizations should assess the potential blast radius if this vulnerability were to be exploited, particularly in environments where Cisco Secure FTD Software is deployed extensively.
