CVE-2022-31486· NVD / CVE Program· CNA Carrier

Command injection via Advanced Networking route add functionality

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.

Fix versions compiled from the vendor, package registries and Microsoft. Verify the vendor's note before upgrading.

No fix version is recorded for this entry. Check the references for vendor advisories.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.

Root cause

User input is inserted as text into a shell command. The shell may interpret special characters in the input as part of the command.

The bug in code
