## What is CVE-2025-60687?

CVE-2025-60687 is a medium-severity command injection vulnerability in n/a, published on 13 Nov 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

An unauthenticated command injection vulnerability exists in the ToToLink LR1200GB Router firmware V9.1.0u.6619_B20230130 within the cstecgi.cgi binary (sub_41EC68 function). The binary reads the "imei" parameter from a web request and verifies only that it is 15 characters long. The parameter is then directly inserted into a system command using sprintf() and executed with system(). Maliciously crafted IMEI input can execute arbitrary commands on the router without authentication.

Weakness: CWE-77 (Improper Neutralization of Special Elements used in a Command)

Check this codebase for CVE-2025-60687 and fix it if it is affected.

What it is: CVE-2025-60687 is a medium-severity command injection vulnerability in n/a, published on 13 Nov 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-60687 exists.

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.
