The affected versions are those before 9.4.0.1 and 9.3.0.2, including 8.3.x. An attacker who can reach the server over the network can exploit this without authentication or user interaction, by crafting request URLs that evade the access restrictions. Successful exploitation can compromise confidentiality, integrity and availability.","provenance":"ai","model":"claude-haiku-5-5","generatedAt":"2026-10-29T07:11:09Z"},"cvss":{"score":9.8,"severity":"CRITICAL","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","provenance":"source","from":"NVD"},"epss":{"score":0.92266,"percentile":0.99823,"date":"2026-10-31","provenance":"source"},"kev":{"dateAdded":"2025-03-03","dueDate":"2025-03-24","ransomware":false,"requiredAction":"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.","notes":"https://support.pentaho.com/hc/en-us/articles/14455394120333--Resolved-Pentaho-BA-Server-Use-of-Non-Canonical-URL-Paths-for-Authorization-Decisions-Versions-before-9-4-0-1-and-9-3-0-2-including-8-3-x-Impacted-CVE-2022-43939- ; https://nvd.nist.gov/vuln/detail/CVE-2022-43939","provenance":"source"},"vulncheckKev":{"dateAdded":"2023-11-17","exploitedFirstSeen":"2023-11-17","ransomware":false,"evidence":[{"url":"https://dashboard.shadowserver.org/statistics/honeypot/vulnerability/map/?day=2023-11-17&host_type=src&vulnerability=cve-2022-43939","date":"2023-11-17"},{"url":"https://dashboard.shadowserver.org/statistics/honeypot/vulnerability/map/?day=2023-11-23&host_type=src&vulnerability=cve-2022-43939","date":"2023-11-23"},{"url":"https://dashboard.shadowserver.org/statistics/honeypot/vulnerability/map/?day=2023-12-25&host_type=src&vulnerability=cve-2022-43939","date":"2023-12-25"},{"url":"https://dashboard.shadowserver.org/statistics/honeypot/vulnerability/map/?day=2024-01-17&host_type=src&vulnerability=cve-2022-43939","date":"2024-01-17"},{"url":"https://dashboard.shadowserver.org/statistics/honeypot/vulnerability/map/?day=2024-01-22&host_type=src&vulnerability=cve-2022-43939","date":"2024-01-22"},{"url":"https://dashboard.shadowserver.org/statistics/honeypot/vulnerability/map/?day=2024-01-23&host_type=src&vulnerability=cve-2022-43939","date":"2024-01-23"},{"url":"https://dashboard.shadowserver.org/statistics/honeypot/vulnerability/map/?day=2024-01-24&host_type=src&vulnerability=cve-2022-43939","date":"2024-01-24"},{"url":"https://dashboard.shadowserver.org/statistics/honeypot/vulnerability/map/?day=2024-01-25&host_type=src&vulnerability=cve-2022-43939","date":"2024-01-25"},{"url":"https://dashboard.shadowserver.org/statistics/honeypot/vulnerability/map/?day=2024-01-26&host_type=src&vulnerability=cve-2022-43939","date":"2024-01-26"},{"url":"https://dashboard.shadowserver.org/statistics/honeypot/vulnerability/map/?day=2024-01-27&host_type=src&vulnerability=cve-2022-43939","date":"2024-01-27"}],"evidenceTotal":492,"provenance":"source"},"exploited":true,"otx":null,"cwes":[{"id":"CWE-647","name":"Use of Non-Canonical URL Paths for Authorization Decisions"}],"references":[{"url":"http://packetstormsecurity.com/files/172296/Pentaho-Business-Server-Authentication-Bypass-SSTI-Code-Execution.html","tags":["Exploit"]},{"url":"https://support.pentaho.com/hc/en-us/articles/14455394120333--Resolved-Pentaho-BA-Server-Use-of-Non-Canonical-URL-Paths-for-Authorization-Decisions-Versions-before-9-4-0-1-and-9-3-0-2-including-8-3-x-Impacted-CVE-2022-43939-","tags":["Vendor Advisory"]},{"url":"http://packetstormsecurity.com/files/172296/Pentaho-Business-Server-Authentication-Bypass-SSTI-Code-Execution.html","tags":["Exploit"]},{"url":"https://support.pentaho.com/hc/en-us/articles/14455394120333--Resolved-Pentaho-BA-Server-Use-of-Non-Canonical-URL-Paths-for-Authorization-Decisions-Versions-before-9-4-0-1-and-9-3-0-2-including-8-3-x-Impacted-CVE-2022-43939-","tags":["Vendor Advisory"]},{"url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2022-43939","tags":["US Government Resource"]}],"techniques":[{"id":"T1190","name":"Exploit Public-Facing Application","tactics":["initial-access"],"provenance":"source","basis":"ctid-kev","bases":["ctid-kev"],"basisDetail":"CTID Mappings Explorer KEV 07/28/2025 (ATT&CK 16.1); capability: Authentication Bypass","mappingType":"exploitation_technique","evidence":[],"comment":"Due to a regex flaw, an attacker can use non-canonical URLs to bypass authentication.
