# CVE-2025-67840: Command injection in n/a

> Authenticated admins can inject OS commands via API parameters to achieve root-level remote code execution, bypassing shell restrictions.

- **Severity:** High 7.2 (`CVSS:3.1/AC:L/AV:N/A:H/C:H/I:H/PR:H/S:U/UI:N`)
- **Exploited in the wild:** Not known
- **Login needed:** An administrator
- **Attackable:** Over the internet
- **Victim action needed:** Not needed
- **Fix available:** No
- **Published:** 3 Mar 2026
- **Updated:** 3 Mar 2026
- **Also known as:** GHSA-j46m-h6wf-3gc4

## What is CVE-2025-67840?

CVE-2025-67840 is a high-severity command injection vulnerability in n/a, published on 3 Mar 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official 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.

Weakness: CWE-78 (Improper Neutralization of Special Elements used in an OS Command)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2025-67840 and fix it if it is affected.

What it is: CVE-2025-67840 is a high-severity command injection vulnerability in n/a, published on 3 Mar 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-67840 in the wild and no public exploit code.

Affected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
