Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-15581 in the wild and no public exploit code.\n\nAffected product: orthanc-server orthanc. 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-2025-15581/ (Markdown: https://insights.sbomify.com/CVE-2025-15581/index.md)","id":"CVE-2025-15581","markdown":"https://insights.sbomify.com/CVE-2025-15581/index.md","name":"CVE-2025-15581","record":{"aliases":["DEBIAN-CVE-2025-15581","DLA-4494-1","GHSA-4wvv-g662-rjm9","UBUNTU-CVE-2025-15581"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Orthanc medical imaging server","requires_auth":"low_privilege","summary":"Attackers can bypass authentication to gain full administrative access to the Orthanc medical imaging server.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"PRJBLK","cpe":[],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Orthanc versions before 1.12.10 are affected by an authorisation logic flaw in the application's HTTP Basic Authentication implementation. \n\nSuccessful exploitation could result in Privilege Escalation, potentially allowing full administrative access.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Auth bypass in orthanc","id":"CVE-2025-15581","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"detronetdip E-commerce Product Management Update authorization","id":"CVE-2025-15582"},"packages":[],"prev":{"headline":"An Insecure Deserialization vulnerability has been discovered in OpenText™ Directory Services.","id":"CVE-2025-15579"},"products":["orthanc"],"published":"2026-02-18","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":"total"},"state":"PUBLISHED","updated":"2026-02-28","vendors":["orthanc-server"]},"summary":"Attackers can bypass authentication to gain full administrative access to the Orthanc medical imaging server.","url":"https://insights.sbomify.com/CVE-2025-15581/"}
