A vulnerability in the web-based management interface of Cisco FXOS Software and Cisco UCS Manager Software could allow an authenticated, local attacker with administrative privileges to perform command injection attacks on an affected system and elevate privileges to root. This vulnerability is due to insufficient input validation of command arguments supplied by the user. An attacker could exploit this vulnerability by authenticating to a device and submitting crafted input to the affected command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system of the affected device with root-level privileges.
The CVSS score for this vulnerability is 6.7, indicating a medium severity level. The implications of this vulnerability are significant, as it could allow attackers to compromise the integrity and availability of critical systems. Organizations must understand the risk associated with this vulnerability, as the potential for command injection could lead to unauthorized access and control over affected devices.
Currently, there are no known public exploits available for this vulnerability, and it is not actively exploited in the wild. However, organizations should prioritize monitoring their systems for any signs of attempted exploitation. Given the nature of this vulnerability, it is crucial for defenders to take immediate action to mitigate potential risks.
Organizations should prioritize patching immediately. Ensuring that all systems are updated to the latest versions is critical to preventing potential exploitation. In the absence of a patch, organizations should implement strict access controls and monitor for unusual activity to reduce the risk of exploitation.
Vulnerability Details
The vulnerability in question is classified under CWE-78, which pertains to OS Command Injection vulnerabilities. The vulnerability is present due to insufficient input validation, allowing crafted input to be submitted by authenticated users with high privileges.
The CVSS score of 6.7 indicates a medium severity, as attackers require local access and high privileges to exploit this vulnerability. The potential impacts include high confidentiality, integrity, and availability impacts.
Technical Analysis
The root cause of this vulnerability is insufficient input validation of command arguments. Attackers with administrative privileges can exploit this flaw by providing crafted input that is not properly validated, allowing them to execute arbitrary commands on the system.
The attack vector is local, and the complexity is low, as attackers only need to authenticate to the device. High privileges are required to exploit this vulnerability, and no user interaction is needed. The confidentiality impact is high, as sensitive data may be exposed, and the integrity and availability impacts are also high, as the attacker could disrupt normal operations.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to critical systems and data through command injection. The potential blast radius of this vulnerability is significant, as it can lead to full system compromise. Organizations must assess their exposure to this vulnerability and implement necessary security measures.
Given the CVSS score and the nature of the vulnerability, organizations should address this in their priority patch cycle. The longer this vulnerability remains unpatched, the greater the risk of exploitation.
Exploitation Status
Signal | Status |
|---|---|
