## What is CVE-2025-2071?

CVE-2025-2071 is a critical command injection vulnerability in FAST LTA Silent Brick WebUI, published on 31 Mar 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A critical OS Command Injection vulnerability has been identified in the FAST LTA Silent Brick WebUI, allowing remote attackers to execute arbitrary operating system commands via specially crafted input. This vulnerability arises due to improper handling of untrusted input, which is passed directly to system-level commands without adequate sanitization or validation. Successful exploitation could allow attackers to execute arbitrary commands on the affected system, potentially resulting in unauthorized access, data leakage, or full system compromise. Affected WebUI parameters are "hd" and "pi".

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

What it is: CVE-2025-2071 is a critical command injection vulnerability in FAST LTA Silent Brick WebUI, published on 31 Mar 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-2071 in the wild and no public exploit code.

Affected product: FAST LTA Silent Brick WebUI. 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.
