CVE-2014-3596 in PeopleSoft Enterprise PeopleTools
Summary
by MITRE
The getCN function in Apache Axis 1.4 and earlier 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-2012-5784.

The vulnerability described in CVE-2014-3596 represents a critical security flaw in Apache Axis 1.4 and earlier versions that undermines the fundamental security mechanism of SSL/TLS certificate validation. This weakness specifically affects the getCN function which is responsible for extracting and validating the common name field from X.509 certificates during SSL handshakes. The vulnerability stems from an incomplete remediation of a previous issue, CVE-2012-5784, creating a persistent security gap that allows attackers to bypass hostname verification checks. The flaw enables man-in-the-middle attacks by permitting certificate spoofing when the target hostname is present in non-CN fields of the certificate, particularly in subjectAltName fields that should be equally validated.
The technical implementation of this vulnerability lies in the improper certificate validation logic within Apache Axis's SSL handling mechanism. When a client establishes an SSL connection to a server, the getCN function should rigorously verify that the server's hostname matches either the Common Name field or any alternative names specified in the subjectAltName extension of the X.509 certificate. However, the flawed implementation fails to properly examine all relevant certificate fields, allowing attackers to place a valid hostname in the subjectAltName field while using a different value in the CN field, or even placing the hostname in a non-CN field entirely. This oversight creates a security bypass where the system accepts certificates that should be rejected based on proper hostname verification standards.
The operational impact of CVE-2014-3596 is severe and far-reaching, particularly for organizations relying on Apache Axis for web services communication. Attackers can exploit this vulnerability to establish fraudulent SSL connections that appear legitimate to vulnerable clients, enabling them to intercept, modify, or steal sensitive data transmitted between clients and servers. The vulnerability affects any application using Apache Axis 1.4 or earlier versions for SSL/TLS connections, potentially compromising authentication mechanisms and data integrity. This weakness is especially dangerous in enterprise environments where web services communicate sensitive business data, financial information, or personal user credentials, as it allows attackers to impersonate legitimate services without detection.
The security implications extend beyond simple certificate validation failures and align with several ATT&CK framework techniques including T1573.001 (Reconnaissance) and T1046 (Network Service Scanning) as attackers can leverage this vulnerability to identify and exploit weak SSL implementations. From a CWE perspective, this vulnerability maps to CWE-295 which specifically addresses improper certificate validation, and CWE-310 which covers cryptographic issues related to key management. Organizations using affected versions should immediately implement mitigation strategies including upgrading to Apache Axis 2.x versions or applying the appropriate security patches that properly validate all certificate fields. Additionally, network administrators should consider implementing additional monitoring and detection mechanisms to identify potential exploitation attempts, as this vulnerability can be particularly difficult to detect through conventional security scanning methods due to its subtle nature in SSL certificate validation logic.
