## What is CVE-2022-31486?

CVE-2022-31486 is a high-severity command injection vulnerability in HID Mercury EP4502, published on 6 Jun 2022. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

An authenticated attacker can send a specially crafted route to the “edit_route.cgi” binary and have it execute shell commands. This vulnerability impacts products based on HID Mercury Intelligent Controllers LP1501, LP1502, LP2500, LP4502, and EP4502 which contain firmware versions prior to 1.303 for the LP series and 1.297 for the EP series. An attacker with this level of access on the device can monitor all communications sent to and from this device, modify onboard relays, change configuration files, or cause the device to become unstable.

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

Check this codebase for CVE-2022-31486 and fix it if it is affected.

What it is: CVE-2022-31486 is a high-severity command injection vulnerability in HID Mercury EP4502, published on 6 Jun 2022. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2022-31486 in the wild and no public exploit code.

Affected product: HID Mercury EP4502. 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.
