AI-suggested
Until an official fix is available, restrict access to the affected PSMP versions to trusted users only and monitor for suspicious activity related to command execution. Follow vendor advisories closely for updates.
Description
Due to incomplete input validation in Idira Privileged Session Manager for SSH (PSMP) versions prior to 15.0.2, 14.6.3, 14.2.5, and 14.0.6, an authenticated, low-privileged user could potentially execute arbitrary commands on the PSMP host. CyberArk Security Bulletins: CA26-17 and CA26-18
Impact
An authenticated low-privileged user could exploit this vulnerability to execute arbitrary commands on the PSMP host, potentially leading to unauthorized system control or compromise. The impact affects confidentiality, integrity, and availability with high scope impact as indicated by the CVSS vector. This could allow attackers to escalate privileges or disrupt system operations.

The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
