This issue stems from the /etc/passwd file being created with group-writable permissions during build time. In certain conditions, an attacker who can execute commands within an affected container, even as a non-root user, can leverage their membership in the root group to modify the /etc/passwd file. 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."}],"affected":[{"vendor":"Red Hat","product":"Red Hat Web Terminal","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"web-terminal/web-terminal-tooling-rhel9","defaultStatus":"affected","cpes":["cpe:/a:redhat:webterminal:1"]}],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2025-57853","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2391106","name":"RHBZ#2391106","tags":["issue-tracking","x_refsource_REDHAT"]}],"datePublic":"2026-04-08T13:45:39.234Z","problemTypes":[{"descriptions":[{"cweId":"CWE-276","description":"Incorrect Default Permissions","lang":"en","type":"CWE"}]}],"x_redhatCweChain":"CWE-276: Incorrect Default Permissions","timeline":[{"lang":"en","time":"2025-08-26T18:47:53.227Z","value":"Reported to Red Hat."},{"lang":"en","time":"2026-04-08T13:45:39.234Z","value":"Made public."}],"credits":[{"lang":"en","value":"Red Hat would like to thank Antony Di Scala and Michael Whale for reporting this issue."}],"providerMetadata":{"orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat","dateUpdated":"2026-04-08T13:55:06.787Z"},"x_generator":{"engine":"cvelib 1.8.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-08T16:06:12.221957Z","id":"CVE-2025-57853","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-04-08T16:06:20.933Z"}}]}}
