## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2026-124010 (Dixell/Copeland XWEB EVO Unauthenticated Command Injection via xwconsole.cgi), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2026-124010 (entry last updated 2026-11-13):
Affected:
- Copeland XWEB EVO: fixed in 5.6.2
Fixed versions: 5.6.2.
Conditions (all must be true for the bug to be hit):
- Copeland XWEB EVO before version 5.6.2 (source: https://www.vulncheck.com/advisories/dixell-copeland-xweb-evo-unauthenticated-command-injection-via-xwconsole-cgi)
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
Attacker needs: network access, no login, no user action.
CISA KEV: CVE-2026-124010 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-124010 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:
