An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-124004 in the wild and no public exploit code.\nExposure: Having an affected version installed is enough. The problem is in what it ships or how it installs, so no code has to call it.\n\nAffected product: Copeland XWEB EVO. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-124004/ (Markdown: https://insights.sbomify.com/CVE-2026-124004/index.md)","id":"CVE-2026-124004","markdown":"https://insights.sbomify.com/CVE-2026-124004/index.md","name":"CVE-2026-124004","record":{"aliases":["GHSA-9vpc-28gc-f73j"],"analysis":{"component_type":"ics_ot","exploitable_when_present":true,"fix_type":"end_of_life","impacts":["account_takeover","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"building automation controller","requires_auth":"none","requires_specific_call":false,"summary":"Unauthenticated remote attackers can log in as full administrator using a hardcoded backdoor password on XWEB EVO controllers; operators of these end-of-service devices should care.","user_interaction":"not_required","vuln_class":"hardcoded_credentials","vulnerable_functions":[]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"VulnCheck","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-798","name":"Use of Hard-coded Credentials"}],"description":"XWEB EVO before 5.6.2 contains a hardcoded backdoor password vulnerability that allows unauthenticated remote attackers to gain full administrative access to the built-in Administrator account.
