CVE-2025-25025 is a medium-severity vulnerability identified in IBM Security Guardium version 12.0. The issue stems from the generation of detailed technical error messages that are returned directly in the browser when certain errors occur. This vulnerability is classified under CWE-209, which involves the exposure of sensitive information through error messages. Specifically, the detailed error messages may contain sensitive internal information such as system configurations, software versions, or other diagnostic data that could be leveraged by a remote attacker to gain insights into the system's architecture or security posture. The vulnerability requires the attacker to have low privileges (PR:L) but does not require user interaction (UI:N), and it can be exploited remotely over the network (AV:N). The CVSS v3.1 base score is 4.3, indicating a medium severity level, primarily due to the confidentiality impact (C:L) without affecting integrity or availability. Although no known exploits are currently reported in the wild, the exposure of sensitive information can facilitate further targeted attacks, such as privilege escalation or exploitation of other vulnerabilities. IBM Security Guardium is a data security and protection platform widely used for database activity monitoring and compliance enforcement, making the confidentiality of its internal information critical to maintaining overall security.

For European organizations, this vulnerability poses a risk primarily to the confidentiality of sensitive information managed by IBM Security Guardium. Since Guardium is often deployed in environments handling critical and regulated data, including financial institutions, healthcare providers, and governmental agencies, exposure of internal system details could aid attackers in crafting more effective attacks against these high-value targets. The detailed error messages could reveal configuration details or software versions that might be vulnerable to other exploits, increasing the attack surface. While the vulnerability does not directly impact system integrity or availability, the potential for information leakage could lead to compliance violations under regulations such as GDPR, especially if the leaked information indirectly exposes personal data or security controls. The risk is heightened in environments where Guardium is accessible over the internet or insufficiently segmented within internal networks.

To mitigate this vulnerability, organizations should implement the following specific measures: 1) Apply any available patches or updates from IBM as soon as they are released to address this issue. Although no patch links are currently provided, monitoring IBM's security advisories is critical. 2) Configure IBM Security Guardium to suppress detailed error messages in production environments, ensuring that only generic error information is displayed to users. This may involve adjusting logging and error handling settings within the application or web server. 3) Restrict access to the Guardium management interface to trusted networks and users only, using network segmentation, firewalls, and VPNs to limit exposure. 4) Implement robust monitoring and alerting to detect unusual access patterns or error message disclosures that could indicate exploitation attempts. 5) Conduct regular security assessments and penetration testing focused on error handling and information disclosure to proactively identify and remediate similar issues. 6) Educate administrators and developers on secure error handling best practices to prevent future occurrences.
