CVE-2008-5328 in Rational ClearQuest
Summary
by MITRE
The ClearQuest Maintenance Tool in IBM Rational ClearQuest before 7 stores the database password in cleartext in an object in a ClearQuest connection profile or export file, which allows remote authenticated users to obtain sensitive information by locating the password object within the object tree during an import process.

The vulnerability identified as CVE-2008-5328 represents a critical security flaw in IBM Rational ClearQuest's Maintenance Tool version 7 and earlier, where database credentials are stored in an insecure manner that exposes sensitive authentication information to unauthorized parties. This weakness specifically affects the ClearQuest connection profile and export file structures, creating a persistent risk for systems that rely on these tools for database management and configuration. The vulnerability stems from the tool's improper handling of authentication credentials during the object serialization process, where password information is embedded within the object tree structure without adequate protection mechanisms.
The technical implementation of this flaw involves the ClearQuest Maintenance Tool's object model where database passwords are serialized into connection profiles and export files using cleartext storage methods. When these files are imported back into the system, the password objects remain accessible within the object tree structure, allowing authenticated users with sufficient privileges to navigate the object hierarchy and extract the stored credentials. This design flaw directly violates security best practices for credential management and represents a classic example of insecure data storage as categorized by CWE-312. The vulnerability is particularly concerning because it does not require elevated privileges beyond standard authenticated user access, making it exploitable by anyone with legitimate access to the ClearQuest environment.
The operational impact of this vulnerability extends beyond simple credential theft, as the exposed database passwords can enable attackers to gain unauthorized access to underlying database systems and potentially escalate their privileges within the enterprise environment. This risk is amplified when considering that ClearQuest is often used in enterprise settings where it manages critical business data and integrates with other security-sensitive applications. The vulnerability creates a persistent threat vector that remains active as long as the affected ClearQuest installations exist, allowing attackers to maintain access even after initial exploitation. From an attack perspective, this vulnerability aligns with ATT&CK technique T1552.001 for unsecured credentials, where adversaries can extract authentication data from system files or configuration objects. The impact is particularly severe in environments where multiple users have access to the ClearQuest tool, as the vulnerability can be exploited by any authenticated user who understands the object structure.
Organizations affected by this vulnerability should implement immediate mitigations including upgrading to IBM Rational ClearQuest version 7 or later, which addresses this specific flaw through improved credential handling mechanisms. System administrators should also conduct thorough audits of existing ClearQuest connection profiles and export files to identify and remove any instances of cleartext password storage. Additional protective measures include implementing network segmentation to limit access to ClearQuest environments, enforcing strict access controls on connection profile files, and establishing regular credential rotation procedures. The vulnerability demonstrates the importance of secure credential management practices and highlights the need for proper object serialization security in enterprise software applications, particularly those handling sensitive authentication information. Organizations should also consider implementing monitoring solutions to detect unauthorized access attempts to ClearQuest configuration files and establish incident response procedures specifically addressing credential exposure scenarios.
