Summary
Copeland XWEB EVO devices have a command injection flaw in how they handle devices.lua templates, which lets an attacker run arbitrary commands with root privileges. The attacker can reach the flaw remotely over the network, but must first log in with high privileges.
Written by anthropic/claude-haiku-5.5 from the sources below. Verify against them.
Read the original description
XWEB EVO 5.2.3 through 5.8.8 contains an authenticated OS command injection vulnerability in the devices.lua template handling, which allows authenticated attackers to execute arbitrary commands by injecting unescaped template source into unzip and related shell commands. Attackers can exploit this flaw through the wlua interpreter to execute arbitrary commands with root privileges on the affected device. This product line reached it's end of service date in March 2026.

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-2026-124008 (Dixell/Copeland XWEB EVO OS Command Injection via devices.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-2026-124008 (entry last updated 2026-11-12):
Affected:
- Copeland XWEB EVO: from 5.2.3, through 5.8.8
Fixed versions: none listed yet.
Conditions (all must be true for the bug to be hit):
- Affects XWEB EVO versions 5.2.3 through 5.8.8 (source: https://www.vulncheck.com/advisories/dixell-copeland-xweb-evo-os-command-injection-via-devices-lua)
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
Attacker needs: network access, high-privilege login, no user action.
CISA KEV: CVE-2026-124008 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-124008 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:
- https://webapps.copeland.com/dixell/Content/Pages/AdvertisingMaterials/ProductNews/XWEB%20EVO%20EoS%20-%20Product_Bulletin_March_2026.pdf

- https://www.vulncheck.com/advisories/dixell-copeland-xweb-evo-os-command-injection-via-devices-lua
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-2026-124008
Is CVE-2026-124008 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?
An authenticated user of the XWEB EVO device can inject operating system commands through the devices.lua component. Those commands run with root privileges on the device.Source: vulncheck.com
Which versions are affected by CVE-2026-124008?
XWEB EVO: from 5.2.3 through 5.8.8.Source: cve.now feed data
Am I affected, and how do I check?
XWEB EVO versions 5.2.3 through 5.8.8 are affected. To check a device, look at its firmware or software version in the device's system information and compare it to that range.Source: vulncheck.com
How do I fix CVE-2026-124008?
The facts provided do not name a fixed version or vendor patch identifiers, so no upgrade target can be given from these sources. Check the Copeland or Dixell advisory for an update.Source: vulncheck.com
