Summary
Copeland XWEB EVO has an OS command injection flaw in its api.lua import and restore actions that lets an attacker run arbitrary commands with root privileges on the underlying system. An attacker can reach it remotely over the network with low-privilege login credentials and needs no user action.
Read the original description
XWEB EVO 5.6.2 through 5.8.8 contains an authenticated OS command injection vulnerability in the api.lua import_preconfiguration and restore actions, where server_url and related server credential fields are concatenated unescaped into a root curl command executed via io.popen. Attackers can inject malicious shell commands through these unfiltered parameters to achieve arbitrary command execution with root privileges on the underlying system. This product line reached it's end of service date in March 2026.
Who should check
Teams running Copeland XWEB EVO controllers, versions 5.6.2 through 5.8.8, with the api.lua import_preconfiguration or restore actions in use.

Check your systems with an agent
Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.
Check whether my systems are affected by CVE-2026-124013 (Dixell/Copeland XWEB EVO OS Command Injection via api.lua), 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-2026-124013 (entry last updated 2026-11-12):
Affected:
- Copeland XWEB EVO: from 5.6.2, through 5.8.8
Fixed versions: none listed yet.
Conditions (all must be true for the bug to be hit):
- Affects XWEB EVO versions 5.6.2 through 5.8.8. (source: https://www.vulncheck.com/advisories/dixell-copeland-xweb-evo-os-command-injection-via-api-lua)
- Exploitable through the api.lua import_preconfiguration and restore actions. (source: https://www.vulncheck.com/advisories/dixell-copeland-xweb-evo-os-command-injection-via-api-lua)
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
Attacker needs: network access, low-privilege login, no user action.
CISA KEV: CVE-2026-124013 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-124013 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:

Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.
Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.

Questions about CVE-2026-124013
Is CVE-2026-124013 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: cve.now feed data
What does this mean?
The api.lua import_preconfiguration and restore actions let a logged-in user inject operating system commands. Successful injection can run arbitrary commands with root privileges on the underlying system.Source: vulncheck.com
Which versions are affected by CVE-2026-124013?
XWEB EVO: from 5.6.2 through 5.8.8.Source: cve.now feed data
Am I affected, and how do I check?
XWEB EVO versions 5.6.2 through 5.8.8 are in the affected range. Compare the installed XWEB EVO version against that range to see whether it falls inside it.Source: vulncheck.com
How do I fix CVE-2026-124013?
The checked facts list no fixed version and no vendor patch, so no upgrade target can be named from them. Check the Copeland advisory for a fix and for any workaround.Source: vulncheck.com
