CVE-2025-25029 is a vulnerability identified in IBM Security Guardium version 12.0, categorized under CWE-116, which pertains to improper encoding or escaping of output. The vulnerability allows a privileged user to download any file on the system due to insufficient escaping of input data. This improper handling of input can lead to unauthorized file access, potentially exposing sensitive system files or data that should otherwise be protected. The vulnerability does not require user interaction and can be exploited remotely (AV:N) with low attack complexity (AC:L), but it does require the attacker to have privileged access (PR:H) on the system. The impact is primarily on confidentiality (C:H), as unauthorized file disclosure can lead to leakage of sensitive information. There is no impact on integrity or availability. The CVSS v3.1 base score is 4.9, indicating a medium severity level. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability arises from the failure to properly escape or encode output, which is a common security weakness that can lead to injection or traversal issues when input is not correctly sanitized before being used in file operations or output contexts.

For European organizations using IBM Security Guardium 12.0, this vulnerability poses a risk of unauthorized disclosure of sensitive data stored on the system. Guardium is typically used for database activity monitoring and data security, so exposure of configuration files, logs, or other sensitive files could lead to leakage of critical security information or personally identifiable information (PII). This could result in compliance violations under GDPR and other data protection regulations, potentially leading to legal and financial penalties. Additionally, attackers with privileged access could leverage this vulnerability to further reconnaissance or lateral movement within the network. Although exploitation requires privileged access, insider threats or compromised administrative accounts could significantly increase the risk. The lack of impact on integrity and availability limits the scope to confidentiality breaches, but the sensitivity of data involved in Guardium environments makes this a notable concern.

European organizations should prioritize the following mitigations: 1) Restrict privileged access strictly to trusted administrators and enforce strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of account compromise. 2) Monitor and audit privileged user activities closely to detect any unusual file access or download attempts. 3) Apply principle of least privilege to limit the number of users with elevated rights on Guardium systems. 4) Regularly check IBM’s security advisories for patches or updates addressing CVE-2025-25029 and apply them promptly once available. 5) Implement network segmentation to isolate Guardium servers from general user networks, reducing exposure. 6) Use file integrity monitoring to detect unauthorized file access or exfiltration attempts. 7) Conduct internal security assessments and penetration testing focusing on privileged user controls and file access mechanisms within Guardium environments.
