IBM FileNet Content Manager version 5.5.2 and 5.5.3 contains a critical security flaw that enables credential logging in plaintext within local log files, creating a significant exposure for unauthorized access. This vulnerability arises from improper handling of web service authentication data during logging operations, where sensitive user credentials are written to disk without adequate protection mechanisms. The flaw specifically affects systems configured in certain deployment scenarios where web service calls are processed through the content manager's logging infrastructure. The vulnerability aligns with CWE-532, which describes information exposure through log files, and represents a direct violation of secure coding practices for credential handling. Attackers with local administrative access to the system can readily retrieve these plaintext credentials from the log files, potentially gaining unauthorized access to the content management system and all associated resources.
The operational impact of this vulnerability extends beyond simple credential theft, as it creates a persistent backdoor for attackers who maintain local system access. Once credentials are extracted from the log files, attackers can impersonate legitimate users and access restricted content, modify documents, and potentially escalate privileges within the FileNet environment. The vulnerability affects the integrity and confidentiality of the entire content management infrastructure, as it allows for unauthorized data access and manipulation. This flaw particularly impacts organizations that rely on FileNet for document management and workflow automation, where the compromise of authentication credentials can lead to significant data breaches and regulatory compliance violations. The vulnerability's impact is amplified by the fact that it requires minimal attack sophistication, as local administrative access is typically sufficient to read the log files containing the plaintext credentials.
Organizations should implement immediate mitigations including restricting local administrative access to system files, implementing proper log file permissions, and configuring the content manager to avoid logging sensitive authentication data. The recommended approach involves disabling or modifying the logging behavior that writes web service credentials to disk, implementing log rotation with proper access controls, and establishing monitoring for unauthorized access to log files. System administrators should also consider implementing additional authentication layers and access controls beyond the basic FileNet authentication mechanisms. This vulnerability demonstrates the importance of secure logging practices and proper credential handling as outlined in the OWASP Top Ten security risks, specifically addressing the issue of sensitive data exposure. Organizations should also review their security configurations against NIST SP 800-53 controls for access control and audit logging to ensure comprehensive protection against similar credential exposure vulnerabilities. Regular security assessments and monitoring of system logs should be implemented to detect and respond to potential exploitation attempts.
