A vulnerability in the CLI and web-based management interface of Cisco UCS Manager Software could allow an authenticated, remote attacker with valid administrative privileges to execute arbitrary commands on the underlying operating system of an affected device. This vulnerability is due to insufficient input validation of command arguments that are 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 an affected device with root-level privileges.
The CVSS score for this vulnerability is 6.5, categorizing it as medium severity. This score indicates that while successful exploitation requires high privileges, the attack complexity is low and can be executed over the network. Organizations should assess the risk this vulnerability poses to their infrastructure.
Risk to organizations includes unauthorized execution of commands, potentially leading to a full compromise of affected devices. Organizations should prioritize patching immediately to mitigate potential risks associated with this vulnerability.
Currently, there are no public exploits or proofs of concept available for this vulnerability, which may provide a temporary window of safety. However, organizations should not rely on this status and should take proactive measures to secure their systems.
Vulnerability Details
The vulnerability primarily affects the CLI and web management interface of Cisco UCS Manager Software. Insufficient input validation allows attackers to manipulate command arguments, leading to arbitrary command execution. The CVE was published on February 25, 2026.
Technical Analysis
The root cause of this vulnerability stems from a failure to properly validate user-supplied command arguments. Attackers may exploit this vulnerability through the network, utilizing a low level of attack complexity, and require high privileges for successful exploitation. No user interaction is necessary, and the impact on confidentiality and integrity is high, while availability remains unaffected.
Risk & Impact Analysis
This vulnerability poses a significant risk to organizations utilizing Cisco UCS Manager Software. Given the potential for arbitrary command execution, the blast radius could be extensive, affecting not only the integrity of the systems but also the confidentiality of sensitive data. Organizations should assess their deployment of affected systems and prioritize patching as part of their security risk management strategy.
