What to do
AI-suggested
Organizations should immediately review and restrict administrative access to the Cohesity TranZman appliance, enforcing strong authentication and monitoring for suspicious admin activity. Network segmentation should isolate the appliance from untrusted networks to reduce interception risks. Since the vulnerability persists in the latest patch at the time of testing, organizations should engage with Cohesity support to obtain updates or workarounds addressing this issue. In the interim, administrators should avoid using vulnerable API endpoints or limit their usage to trusted environments. Implementing strict input validation and sanitization on all user-supplied parameters is critical; if possible, disable or restrict features that allow command execution via the web interface. Employ network-level protections such as TLS interception prevention and use of secure management channels to prevent request tampering. Regularly audit appliance logs for anomalous commands or access patterns. Finally, prepare incident response plans for potential exploitation scenarios involving this vulnerability.
Description
Multiple authenticated OS command injection vulnerabilities exist in the Cohesity (formerly Stone Ram) TranZman 4.0 Build 14614 through TZM_1757588060_SEP2025_FULL.depot web application API endpoints (including Scheduler and Actions pages). The appliance directly concatenates user-controlled parameters into system commands without sufficient sanitisation, allowing an authenticated admin user to inject and execute arbitrary OS commands with root privileges. An attacker can intercept legitimate requests (e.g.during job creation or execution) using a proxy and modify parameters to include shell metacharacters, achieving remote code execution on the appliance. This completely bypasses the intended CLISH restricted shell confinement and results in full system compromise. The vulnerabilities persist in Release 4.0 Build 14614 including the latest patch (as of the time of testing) TZM_1757588060_SEP2025_FULL.depot.
