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-2025-11566 in the wild and no public exploit code.\n\nAffected product: Schneider Electric PowerChute™ Serial Shutdown. 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-2025-11566/ (Markdown: https://insights.sbomify.com/CVE-2025-11566/index.md)","id":"CVE-2025-11566","markdown":"https://insights.sbomify.com/CVE-2025-11566/index.md","name":"CVE-2025-11566","record":{"aliases":["GHSA-w9rv-x77p-3mvc"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"PowerChute Serial Shutdown","requires_auth":"none","summary":"An attacker on the local network can bypass authentication limits to gain user account access via the shutdown endpoint.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"CWE-307: Improper Restriction of Excessive Authentication Attempts vulnerability exists that would allow an attacker on the local network to gain access to the user account by performing an arbitrary number of authentication attempts with different credentials on the /REST/shutdownnow endpoint.","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":"Auth bypass in PowerChute™ Serial Shutdown","id":"CVE-2025-11566","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in PowerChute™ Serial Shutdown","id":"CVE-2025-11567"},"packages":[],"prev":{"headline":"Path traversal in PowerChute™ Serial Shutdown","id":"CVE-2025-11565"},"products":["PowerChute™ Serial Shutdown"],"published":"2025-11-12","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-12","vendors":["Schneider Electric"]},"summary":"An attacker on the local network can bypass authentication limits to gain user account access via the shutdown endpoint.","url":"https://insights.sbomify.com/CVE-2025-11566/"}
