CVE-2025-25023: IBM Security Guardium Privilege Escalation

CVE-2025-25023 Overview

CVE-2025-25023 affects IBM Security Guardium versions 11.4 and 12.1. A privileged user can read arbitrary files on the system because of incorrect privilege assignment [CWE-266]. The flaw sits in how the product assigns privileges to authenticated administrative users, letting them exceed their intended file-access boundary.

The weakness allows unauthorized disclosure of sensitive files stored on the appliance. These files can include configuration data, credentials, keys, and audit records relevant to the database activity monitoring function Guardium performs.

Critical Impact
An authenticated privileged user can read any file on the Guardium system, exposing sensitive data stored on the appliance.

Technical Details for CVE-2025-25023

Vulnerability Analysis

IBM Security Guardium is a data security and compliance platform that monitors database activity and enforces access policies. The vulnerability allows a privileged user to read any file on the appliance, bypassing the file-level access scope expected for their role.

The weakness is classified under CWE-266: Incorrect Privilege Assignment. Guardium grants an authenticated administrative role file-read capability that extends beyond the files required for its documented function. The result is unauthorized disclosure of files owned by other components or the underlying operating system.

Exploitation requires network access to the Guardium management interface and valid high-privilege credentials. No user interaction is required. Confidentiality impact is high, while integrity and availability are not affected.

Root Cause

The root cause is incorrect privilege assignment within Guardium's access control model. A role that should be restricted to a specific subset of files instead inherits broader read permissions. This allows the account to open and retrieve the contents of files outside its intended scope, including sensitive configuration, credential, and log files.

Attack Vector

An attacker who already holds privileged Guardium credentials sends requests through the authenticated administrative interface to read arbitrary files. Because the account is already trusted, the system does not reject the read operation. The attack is network reachable and does not require physical access or user interaction.

No public proof-of-concept or exploit code is listed for CVE-2025-25023. Refer to the IBM Support Documentation for product-specific details.

Detection Methods for CVE-2025-25023

Indicators of Compromise

Administrative sessions that access files outside the normal Guardium operational path, such as /etc/shadow, private key stores, or OS configuration files.
Unexpected read operations against credential, token, or certificate files on the Guardium appliance.
Privileged user activity originating from unusual source IP addresses or occurring outside maintenance windows.

Detection Strategies

Review Guardium audit logs for file-access actions performed by privileged accounts and correlate against documented administrative tasks.
Enable and monitor operating system audit records on the appliance for reads of sensitive files by Guardium service accounts.
Alert on repeated or sequential access to multiple sensitive files by the same privileged session.

Monitoring Recommendations

Forward Guardium administrative and OS-level audit events to a centralized logging or SIEM platform for correlation.
Baseline normal file-access patterns for each privileged role and alert on deviations.
Track changes to privileged account membership and credential use on Guardium 11.4 and 12.1 appliances.

How to Mitigate CVE-2025-25023

Immediate Actions Required

Apply the fix referenced in the IBM Support Documentation for Guardium 11.4 and 12.1.
Rotate credentials, API keys, and certificates stored on the Guardium appliance if unauthorized privileged access is suspected.
Review and reduce the number of accounts holding privileged roles on Guardium.

Patch Information

IBM has published remediation guidance for CVE-2025-25023 in advisory node/7230467. Administrators should follow the IBM advisory to apply the appropriate patch level for Guardium 11.4 and 12.1 deployments. Confirm the installed version after patching to verify remediation.

Workarounds

Restrict network reachability of the Guardium administrative interface to a limited management network or jump hosts.
Enforce strong authentication and multi-factor authentication for all privileged Guardium accounts until the patch is applied.
Audit the privileged role assignments and remove any accounts that do not require administrative access.

bash

# Verify installed Guardium version against the fixed release in the IBM advisory
# Replace <appliance> with your Guardium host
ssh cli@<appliance> 'show build'
