The CVE-2019-17082 vulnerability represents a critical missing authentication flaw in OpenText™ AccuRev for LDAP Integration version 2017.1, specifically impacting the authentication mechanisms for critical functions within the source control system. This vulnerability falls under the CWE-305 category of Authentication Bypass Through User Identification, where the system fails to properly validate user credentials before granting access to protected resources. The flaw manifests in the LDAP integration component where valid AccuRev usernames can bypass the standard authentication process and gain unauthorized access to source control repositories without providing the correct password.
The technical implementation of this vulnerability stems from inadequate validation of authentication tokens or session management within the LDAP integration framework. When a user attempts to authenticate through the AccuRev system with valid credentials, the system should verify the password before granting access to critical functions such as source code repository access, file operations, and version control activities. However, due to the missing authentication check, the system accepts valid usernames even when the corresponding password is not provided or is incorrect. This creates a scenario where an attacker could potentially exploit this weakness by simply knowing a valid username within the AccuRev system, effectively bypassing the password requirement entirely.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it fundamentally undermines the security model of the source control system. Attackers could leverage this vulnerability to gain access to sensitive source code repositories, manipulate version control histories, perform unauthorized file operations, and potentially introduce malicious code into the development environment. The vulnerability particularly affects organizations that rely on AccuRev for critical software development workflows, where source code integrity and access control are paramount. This issue creates a significant risk for enterprise environments where multiple developers interact with shared repositories, as it could enable privilege escalation attacks or unauthorized modifications to critical software components. The vulnerability aligns with ATT&CK technique T1078.004 for Valid Accounts and T1566.001 for Phishing, as it exploits legitimate user accounts to bypass authentication mechanisms.
Organizations affected by this vulnerability should implement immediate mitigations including applying the vendor-provided patches or updates, implementing additional authentication layers, and conducting thorough security assessments of their AccuRev environments. The recommended approach involves configuring the LDAP integration to enforce strict authentication requirements and ensuring that all user accounts are properly validated before granting access to critical functions. Security teams should also consider implementing network segmentation, monitoring for unusual authentication patterns, and conducting regular penetration testing to identify similar vulnerabilities in their source control infrastructure. The vulnerability demonstrates the importance of proper authentication design and the critical need for comprehensive security testing of integration components that handle user credentials and access control mechanisms.
