It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-57851 in the wild and no public exploit code.\n\nAffected product: Red Hat Multicluster Engine for Kubernetes. 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-2025-57851/ (Markdown: https://insights.sbomify.com/CVE-2025-57851/index.md)","id":"CVE-2025-57851","markdown":"https://insights.sbomify.com/CVE-2025-57851/index.md","name":"CVE-2025-57851","record":{"aliases":["GHSA-87qg-cwpg-cjvw"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Kubernetes container image","requires_auth":"high_privilege","summary":"An attacker with command execution in a Multicluster Engine container can escalate to root by modifying the group-writable /etc/passwd file.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"advanced_cluster_management_for_kubernetes","vendor":"redhat"}],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"A container privilege escalation flaw was found in certain Multicluster Engine for Kubernetes images.

This could allow the attacker to add a new user with any arbitrary UID, including UID 0, leading to full root privileges within the container.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Mce: privilege escalation via excessive /etc/passwd permissions","id":"CVE-2025-57851","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Openshift-ai: privilege escalation via excessive /etc/passwd permissions","id":"CVE-2025-57852"},"packages":[],"prev":{"headline":"Codeready-ws: privilege escalation via excessive /etc/passwd permissions","id":"CVE-2025-57850"},"products":["Multicluster Engine for Kubernetes"],"published":"2026-04-08","related":[{"cvss_score":8.2,"headline":"Open Cluster Management (OCM): Cross-cluster privilege escalation via improper Kubernetes client certificate renewal validation","id":"CVE-2026-4740","kev_date_added":null,"published":"2026-04-07"},{"cvss_score":7.8,"headline":"Privilege escalation in RHACM","id":"CVE-2023-3027","kev_date_added":null,"published":"2023-06-05"},{"cvss_score":7.8,"headline":"Server-side request forgery in RHACM","id":"CVE-2022-3841","kev_date_added":null,"published":"2023-01-11"},{"cvss_score":7.1,"headline":"Insights-client-rhel9: insights-client: pull-secret bearer token written to logs on non-200 ccx response","id":"CVE-2026-71474","kev_date_added":null,"published":"2026-08-11"},{"cvss_score":6.8,"headline":"Insights-client-rhel9: insights-client: spoke-controlled clusterid injected unencoded into insights api url path","id":"CVE-2026-71475","kev_date_added":null,"published":"2026-08-11"},{"cvss_score":6.5,"headline":"Insights-client: insights-client: clusterrole grants cluster-wide secrets get/list/watch beyond least privilege","id":"CVE-2026-71846","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":6.5,"headline":"SQL injection in Red Hat Advanced Cluster Management for Kubernetes","id":"CVE-2022-2238","kev_date_added":null,"published":"2022-09-01"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-01","vendors":["Red Hat"]},"summary":"An attacker with command execution in a Multicluster Engine container can escalate to root by modifying the group-writable /etc/passwd file.","url":"https://insights.sbomify.com/CVE-2025-57851/"}
