Summary
Copeland XWEB EVO is affected by an authentication bypass that lets a remote attacker, without logging in, set the password of an account flagged to reset at next login, such as a newly onboarded operator account. This clears the expiration flag and gives the attacker an immediately usable logged-in foothold on the system.
Read the original description
XWEB EVO 5.6.2 through 5.8.8 contains an authentication bypass vulnerability that allows unauthenticated attackers to set the password of any account flagged must-reset-at-next-login by exploiting missing session validation in the users.lua update_password action. Attackers can reset the password of newly onboarded operator accounts, clearing the password_expiration flag and gaining an immediately usable authenticated foothold on the 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. This product line reached end of service 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-2026-124015 (Dixell/Copeland XWEB EVO Authentication Bypass via users.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-2026-124015 (entry last updated 2026-11-13):
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-authentication-bypass-via-users-lua)
- Exploitable against accounts flagged must-reset-at-next-login, such as newly onboarded operator accounts. (source: https://www.vulncheck.com/advisories/dixell-copeland-xweb-evo-authentication-bypass-via-users-lua)
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-2026-124015 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-124015 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

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-2026-124015
Is CVE-2026-124015 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?
Unauthenticated attackers can set the password of accounts flagged must-reset-at-next-login. This clears the flag and gives an immediately usable authenticated foothold on the system.Source: vulncheck.com
Which versions are affected by CVE-2026-124015?
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 affected. The exposure is limited to accounts flagged must-reset-at-next-login, such as newly onboarded operator accounts, so compare the installed XWEB EVO version against that range.Source: vulncheck.com
How do I fix CVE-2026-124015?
The checked facts name no fixed version and no vendor patch ids, so no upgrade target can be given from them. Check the vendor's advisory for a fix.Source: vulncheck.com
