Summary
by MITRE • 09/18/2026
IBM Guardium Data Protection 12.2 is vulnerable to a command injection vulnerability in the import remotelog_config file CLI command. A highly privileged authenticated user can inject shell commands through the filename parameter, potentially resulting in arbitrary command execution with root privileges and impact to the confidentiality, integrity, and availability of the affected system.

The IBM Guardium Data Protection version 12.2 contains a critical security flaw within its Command Line Interface (CLI) functionality, specifically affecting the import remotelog_config file operation. This vulnerability is classified as a command injection weakness, which allows an attacker to execute arbitrary operating system commands on the underlying host infrastructure. The root cause of this issue lies in insufficient input validation and sanitization mechanisms applied to the filename parameter during the configuration import process. When a user provides a value for this parameter, the application fails to adequately filter or escape special characters that have meaning in shell environments, such as semicolons, pipes, or ampersands. Consequently, these inputs are interpreted directly by the system shell rather than being treated strictly as literal file path strings, creating an avenue for malicious code execution.
The exploitation of this vulnerability requires a high level of privilege and authentication within the IBM Guardium environment. A highly privileged authenticated user must be able to access the CLI interface and invoke the import remotelog_config command with a crafted filename argument. While the requirement for prior authentication limits the attack surface compared to unauthenticated remote code execution flaws, it does not mitigate the severity given that insider threats or compromised administrative credentials are significant vectors in enterprise security landscapes. Once triggered, the injected shell commands execute with root privileges due to the elevated permissions typically associated with system configuration management tasks. This results in a complete compromise of the affected system's confidentiality, integrity, and availability, as an attacker gains full control over the operating system hosting the Guardium appliance.
From a technical classification perspective, this vulnerability aligns closely with Common Weakness Enumeration (CWE) ID 78, known as Improper Neutralization of Special Elements used in an OS Command, commonly referred to as OS Command Injection. The attack vector is categorized under CWE-20 for improper input validation and potentially CWE-436 if it involves interpretation ambiguity. In terms of the MITRE ATT&CK framework, this vulnerability facilitates techniques associated with Execution via command-line interface (T1059) and Privilege Escalation to root or system-level access. The ability to execute commands as root means that an attacker can install persistent backdoors, exfiltrate sensitive data protected by Guardium, modify audit logs to cover tracks, or disrupt services leading to denial of service conditions.
The operational impact extends beyond the immediate compromise of the IBM Guardium server itself. Since Guardium is responsible for monitoring and protecting database activity across an organization's infrastructure, a compromised instance can lead to blind spots in security visibility. Attackers may alter logging configurations to hide their activities within other databases or systems being monitored by Guardium. Furthermore, because root access allows modification of system binaries and configuration files, the attacker could pivot from this single point of compromise to attack other network segments that rely on accurate audit trails for compliance and forensic analysis. This undermines the core value proposition of data protection solutions, which is ensuring trust in data integrity and regulatory compliance.
Mitigation strategies must focus on both immediate remediation and long-term architectural improvements. The primary defense is applying the official patch or update provided by IBM to upgrade from version 12.2 to a fixed release where this input validation flaw has been addressed. Until patches are applied, organizations should enforce strict access controls limiting CLI usage to only those administrators who absolutely require it, utilizing multi-factor authentication and rigorous credential management practices to reduce the risk of privilege compromise. Additionally, implementing network segmentation can isolate Guardium appliances from general user networks, reducing exposure to potential lateral movement if an administrative account is breached. Input validation improvements should also be considered in any custom integrations or scripts that interact with the CLI, ensuring that all parameters are strictly validated against expected formats before being passed to system commands. Regular auditing of privileged accounts and monitoring for unusual command-line activity can help detect exploitation attempts early.
