The attacker can reach the flaw remotely over the network, but must first log in with high privileges. Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources. ## Who should check Teams running Copeland XWEB EVO controllers, versions 5.2.3 through 5.8.8, where authenticated users can reach the devices.lua template handling. Source: https://www.vulncheck.com/advisories/dixell-copeland-xweb-evo-os-command-injection-via-devices-lua ("XWEB EVO 5.2.3 through 5.8.8 contains an authenticated OS command injection vulnerability") ## Affected - Copeland XWEB EVO: from 5.2.3, through 5.8.8 ## 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.

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 2026-11-13): 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://webapps.copeland.com/Dixell/Pages/SystemSoftwareUpdate - 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. Entry: https://cve.now/CVE-2026-124008 For follow-up questions, use the cve.now MCP server at https://mcp.cve.now/mcp (no authentication), for example execute with name cve.get and arguments {"id": "CVE-2026-124008"}. ``` ## FAQ ### 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: https://cve.now/CVE-2026-124008 ### What does this mean? The bug is an OS command injection in devices.lua that requires authentication. An attacker who can log in can run arbitrary commands with root privileges on the affected device. Source: https://www.vulncheck.com/advisories/dixell-copeland-xweb-evo-os-command-injection-via-devices-lua ### Which versions are affected by CVE-2026-124008? XWEB EVO: from 5.2.3 through 5.8.8. Source: https://cve.now/CVE-2026-124008 ### Am I affected, and how do I check? XWEB EVO versions 5.2.3 through 5.8.8 are affected. To check a device, compare its firmware version with that range; the checked facts do not name a specific command or setting to read it. Source: https://www.vulncheck.com/advisories/dixell-copeland-xweb-evo-os-command-injection-via-devices-lua ### How do I fix CVE-2026-124008?
