CVE-2006-5328 in OpenBase
Summary
by MITRE
OpenBase SQL 10.0 and earlier, as used in Apple Xcode 2.2 2.2 and earlier and possibly other products, allows local users to create arbitrary files via a symlink attack on the simulation.sql file.

The vulnerability identified as CVE-2006-5328 represents a critical security flaw in OpenBase SQL version 10.0 and earlier implementations, specifically affecting Apple Xcode versions 2.2 and earlier. This issue stems from inadequate file handling mechanisms during the simulation.sql file creation process, creating a path traversal condition that enables local attackers to manipulate the file system through symbolic link manipulation. The vulnerability exists within the context of software development environments where database simulation files are automatically generated during the build process, making it particularly dangerous in development workflows where privileged access is typically assumed.
The technical exploitation of this vulnerability occurs through a symlink attack vector that leverages the predictable naming convention of the simulation.sql file. When the affected OpenBase SQL component processes a simulation request, it attempts to create the simulation.sql file without proper validation of the file path or symbolic link resolution. An attacker with local access can establish a symbolic link with the name simulation.sql that points to a target file outside the intended directory structure, effectively bypassing normal file creation restrictions. This attack pattern aligns with CWE-367, which describes the dangerous use of a file system operation with an incorrect path, and represents a classic example of a race condition vulnerability where the timing of file creation and symbolic link establishment enables unauthorized file access.
The operational impact of this vulnerability extends beyond simple file creation, as it allows attackers to potentially overwrite critical system files, inject malicious content into database simulation environments, or escalate privileges within the development environment. Since this vulnerability affects Apple Xcode development tools, it poses significant risk to software development teams working on iOS and macOS applications, potentially compromising the integrity of the entire development pipeline. The attack requires only local system access, making it particularly concerning as it can be exploited by malicious insiders or through compromised user accounts with development privileges. The vulnerability affects not just Xcode but potentially other products using the same OpenBase SQL implementation, creating a widespread risk across multiple software development environments.
Mitigation strategies for CVE-2006-5328 should focus on immediate software updates and implementation of proper file system access controls. Organizations should prioritize updating to versions of OpenBase SQL and Apple Xcode that address this vulnerability, as the original affected versions are no longer supported. System administrators should implement strict file path validation and ensure that symbolic link resolution is properly handled during file creation operations. The remediation process should include disabling unnecessary file creation capabilities in development environments and implementing proper privilege separation to limit the impact of potential exploitation. Additionally, security monitoring should be enhanced to detect suspicious file creation patterns and symbolic link manipulation within development directories. This vulnerability demonstrates the importance of proper input validation and file system security practices, aligning with ATT&CK technique T1059.007 for execution through scripting and T1548.001 for privilege escalation through file permissions, making it a critical concern for both development security and enterprise security posture management.
