## Affected

- Copeland XWEB EVO: fixed in 5.6.2

## Description

XWEB EVO before 5.6.2 contains a pre-authentication OS command injection vulnerability that allows unauthenticated remote attackers to execute arbitrary commands by injecting shell metacharacters into the password field. Attackers can exploit the unescaped interpolation of the password value into the hashpass invocation within login.lua, cleanout.lua, and api.lua to achieve root-level command execution via the setuid wlua interpreter. This product line reached it's end of service date in March 2026.

## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2026-124007 (Dixell/Copeland XWEB EVO Pre-Auth OS Command Injection via Password Field), 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-2026-124007 (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):
- Affects XWEB EVO firmware before 5.6.2 (source: https://www.vulncheck.com/advisories/dixell-copeland-xweb-evo-pre-auth-os-command-injection-via-password-field)
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-2026-124007 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-124007 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:

## FAQ

### Is CVE-2026-124007 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

Source: https://cve.now/CVE-2026-124007

### What does this mean?

The XWEB EVO web interface passes the password field to an OS command without proper checks, so a user who has not logged in can run arbitrary commands on the device. The commands run with root-level privileges.
