An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-52666 exists.\n\nAffected product: Revive-Adserver Revive Adserver. 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-2025-52666/ (Markdown: https://insights.sbomify.com/CVE-2025-52666/index.md)","id":"CVE-2025-52666","markdown":"https://insights.sbomify.com/CVE-2025-52666/index.md","name":"CVE-2025-52666","record":{"aliases":["GHSA-78v8-2mcw-xgcf"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Ad server software","requires_auth":"high_privilege","summary":"An administrator can trigger a fatal PHP error via improper format character handling, disabling the admin console in Revive Adserver.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"revive_adserver","vendor":"revive-adserver"}],"cvss":{"score":2.7,"severity":"low","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L","version":"3.0"},"cwes":[{"id":"CWE-134","name":"Use of Externally-Controlled Format String"}],"description":"Improper neutralisation of format characters in the settings of Revive Adserver 5.5.2 and 6.0.1 and earlier versions causes an administrator user to disable the admin user console due to a fatal PHP error.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Denial of service in Revive Adserver","id":"CVE-2025-52666","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"revive-adserver:revive_adserver","products":["revive-adserver:revive_adserver"],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in Revive Adserver","id":"CVE-2025-52667"},"packages":[],"prev":{"headline":"Missing authorization in UniFi Access Application","id":"CVE-2025-52665"},"products":["Revive Adserver"],"published":"2025-11-20","related":[{"cvss_score":9.8,"headline":"Security feature bypass in Revive Adserver All versions before 3.2.3","id":"CVE-2016-9124","kev_date_added":null,"published":"2017-03-28"},{"cvss_score":9.8,"headline":"Auth bypass in Revive Adserver All versions before 3.2.3","id":"CVE-2016-9125","kev_date_added":null,"published":"2017-03-28"},{"cvss_score":9.8,"headline":"Deserialization in n/a","id":"CVE-2017-5830","kev_date_added":null,"published":"2017-03-03"},{"cvss_score":9,"headline":"Other in Revive Adserver All versions before 3.2.5 and 4.0.0","id":"CVE-2016-9470","kev_date_added":null,"published":"2017-03-28"},{"cvss_score":8.8,"headline":"Code injection in Adserver","id":"CVE-2026-50741","kev_date_added":null,"published":"2026-06-26"},{"cvss_score":8.8,"headline":"Missing authorization in Revive Adserver","id":"CVE-2025-48986","kev_date_added":null,"published":"2025-11-20"},{"cvss_score":8.8,"headline":"SQL injection in Revive Adserver","id":"CVE-2025-52664","kev_date_added":null,"published":"2025-10-30"}],"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-20","vendors":["Revive"]},"summary":"An administrator can trigger a fatal PHP error via improper format character handling, disabling the admin console in Revive Adserver.","url":"https://insights.sbomify.com/CVE-2025-52666/"}
