CVE-2025-67840: Multiple authenticated OS command injection vulnerabilities exist in the Cohesity (formerly Stone Ram) TranZman 4.0 Build 14614 through TZM_1757588060_SEP2025

Multiple authenticated OS command injection vulnerabilities exist in the Cohesity (formerly Stone Ram) TranZman 4.0 Build 14614 through TZM_1757588060_SEP2025_F

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.

What it means for a small business

If your business uses Tranzman, install the vendor's update. If you're not sure whether you use it, ask whoever manages your computers.

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 3.8%, top 10% of all CVEs. That’s above average: worth scheduling this week. Scored October 28, 2026, updated daily.

Check your own setup

Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
Server check: what your web server says about itself, and whether that version has known flaws.
