CVE-2025-1950 Overview
IBM Hardware Management Console - Power Systems versions V10.2.1030.0 and V10.3.1050.0 contain a local code execution vulnerability due to improper validation of libraries from untrusted sources. This vulnerability allows a local user with limited privileges to execute arbitrary commands on the affected system, potentially compromising the integrity and confidentiality of the entire Power Systems infrastructure managed by the HMC.
Critical Impact
A local attacker can leverage improper library validation to execute arbitrary commands, potentially gaining full control over the Hardware Management Console and the Power Systems it manages.
Affected Products
- IBM Hardware Management Console V10.2.1030.0
- IBM Hardware Management Console V10.3.1050.0
- IBM Power Systems managed by affected HMC versions

Technical Details for CVE-2025-1950
Vulnerability Analysis
This vulnerability is classified under CWE-114 (Process Control), which describes scenarios where an application's behavior can be influenced by loading external code modules or libraries that are not properly validated. In the context of the IBM Hardware Management Console, the system fails to adequately verify the authenticity and integrity of libraries before loading and executing them.
The Hardware Management Console serves as the central management interface for IBM Power Systems, making it a high-value target. Successful exploitation allows an attacker to escalate from a low-privileged local user to executing commands with elevated privileges, potentially affecting confidentiality, integrity, and availability of managed systems.
Root Cause
The root cause of CVE-2025-1950 lies in the improper validation of library sources within the IBM Hardware Management Console. The application does not sufficiently verify that libraries being loaded originate from trusted and authorized sources before executing their code. This lack of validation creates an opportunity for attackers to substitute malicious libraries that the HMC will load and execute.
Attack Vector
The attack requires local access to the system with low-level user privileges. An attacker can exploit this vulnerability by:
- Placing a malicious library in a location where the HMC searches for dynamic libraries
- Manipulating environment variables or configuration settings to redirect library loading paths
- Replacing legitimate libraries with malicious versions containing attacker-controlled code
When the HMC loads these untrusted libraries, the malicious code executes within the context of the application, allowing command execution with elevated privileges.
The vulnerability is particularly concerning in enterprise environments where Power Systems manage critical workloads. Compromising the HMC could allow an attacker to manipulate server configurations, access sensitive management data, or disrupt operations across multiple managed systems.
Detection Methods for CVE-2025-1950
Indicators of Compromise
- Unexpected library files appearing in HMC system directories or library paths
- Unusual process spawning or command execution from HMC-related processes
- Modified environment variables related to library loading (e.g., LD_LIBRARY_PATH, LD_PRELOAD)
- Unauthorized changes to HMC configuration files or library search paths
Detection Strategies
- Monitor file system integrity for unauthorized modifications to library directories
- Implement auditing for library loading operations and dynamic linker activity
- Track process execution chains originating from HMC services
- Alert on unusual privilege escalation patterns from low-privileged user accounts
Monitoring Recommendations
- Enable comprehensive audit logging on HMC systems to capture library loading events
- Deploy endpoint detection and response (EDR) solutions capable of detecting library injection attacks
- Implement file integrity monitoring (FIM) on critical HMC directories
- Review HMC access logs regularly for suspicious local user activity
How to Mitigate CVE-2025-1950
Immediate Actions Required
- Apply the security patch provided by IBM immediately on all affected HMC systems
- Audit local user accounts with access to HMC systems and remove unnecessary privileges
- Implement strict access controls limiting which users can write to library directories
- Review and harden library search path configurations
Patch Information
IBM has released a security update to address this vulnerability. Administrators should consult the IBM Support Page for detailed patching instructions and download links. The patch implements proper validation of library sources before loading, preventing the execution of untrusted code.
Affected versions:
- Hardware Management Console V10.2.1030.0
- Hardware Management Console V10.3.1050.0
Workarounds
- Restrict local user access to only essential personnel pending patch deployment
- Configure file system permissions to prevent unauthorized writes to library directories
- Implement application allowlisting to control which libraries can be loaded
- Monitor and alert on any attempts to modify library paths or load unsigned libraries
- Isolate HMC systems on dedicated management networks with limited access
# Example: Restrict library directory permissions
chmod 755 /opt/hmc/lib
chown root:root /opt/hmc/lib
# Audit library directory for unauthorized files
find /opt/hmc/lib -type f -mtime -7 -ls
