CVE-2022-43939
Hitachi Vantara Pentaho Business Analytics Server ≤ 9.3.0.2
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2022-43939 is a high-severity Use of Non-Canonical URL Paths for Authorization Decisions (CWE-647) vulnerability in Hitachi Vantara Pentaho Business Analytics Server. Its CVSS base score is 8.6 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Steganography (T1001.002); ranked in the top 0.2% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Hitachi Vantara Pentaho Business Analytics Server versions before 9.4.0.1 and 9.3.0.2, including the 8.3.x branch, contain an authorization flaw in which security restrictions are enforced using non-canonical URL paths. The weakness, tracked as CVE-2022-43939 and assigned CWE-647, permits an unauthenticated network attacker to bypass intended access controls by supplying alternate URL representations that the server does not normalize before performing authorization decisions.
An attacker can therefore reach administrative or restricted endpoints that should be protected, resulting in partial confidentiality and integrity impacts together with high availability impact as reflected in the CVSS 8.6 vector. Public proof-of-concept material demonstrates that the bypass can be chained with server-side template injection to achieve remote code execution.
Vendor guidance published by Hitachi Vantara directs customers to upgrade to the fixed releases 9.4.0.1 or 9.3.0.2; the same advisory is referenced in CISA’s Known Exploited Vulnerabilities catalog, confirming that the issue has been observed in active exploitation campaigns. The associated EPSS score remains elevated near 0.93, indicating sustained exploitation interest after disclosure.

Enforcing well-defined authorization policies prevents URL canonicalization bypasses when path handling is included in the implementation.

A.8.26 requires identifying and specifying requirements including segregation of access, resilience against SQL injections/malicious attacks, input validation, and authorization processes, which can address non-canonical URL path bypasses when risk-assessed and specified; however this is only a minority slice as the control does not mandate or enforce any specific authorization mechanism and leaves most implementation details to the acquirer/developer.
Secure-coding standards that require URL canonicalization and safe path handling eliminate the root cause of the weakness.
Security testing can discover non-canonical URL bypasses but does not itself implement the preventive control.
Enforcing strict access-control rules on canonical resource identifiers directly prevents authorization bypass via non-canonical URLs.
