http/conn/ssl/AbstractVerifier.java in Apache Commons HttpClient before 4.2.3 does not properly verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via a certificate with a subject that specifies a common name in a field that is not the CN field. NOTE: this issue exists because of an incomplete fix for CVE-2012-5783.

Security readout for executives and security teams

This vulnerability affects older Apache Commons HttpClient hostname checks for HTTPS. A connection could accept a certificate where the expected name appears in the wrong certificate field, weakening server identity checks and enabling impersonation by a network-positioned attacker. Exposure is most likely in legacy Java applications or vendor products that bundle or package Apache Commons HttpClient before 4.2.3. The supplied affected-product data is incomplete, so confirm through SBOMs, dependency inventories, and vendor advisories. Treat as a legacy dependency hygiene issue with meaningful confidentiality risk. Prioritize internet-facing or sensitive Java services, but do not treat it as emergency active exploitation based on the provided evidence. Mitigation focus: Identify Apache Commons HttpClient versions in application and platform inventories.; Upgrade or patch versions before 4.2.3 using vendor-supported packages.; Review Red Hat, Ubuntu, HPE, and Apache guidance for product-specific fixes..
