CVE-2025-25045 is a vulnerability identified in IBM InfoSphere Information Server version 11.7, categorized under CWE-209, which involves the generation of error messages containing sensitive information. Specifically, this vulnerability allows an authenticated user to receive detailed technical error messages during certain requests. These error messages inadvertently expose sensitive internal information about the system, such as configuration details, system paths, or other diagnostic data that should not be disclosed. While the vulnerability requires authentication, the exposure of such information can be leveraged by attackers to gain deeper insights into the system's architecture and security posture, potentially facilitating subsequent attacks such as privilege escalation, injection attacks, or targeted exploitation of other vulnerabilities. The vulnerability does not currently have known exploits in the wild, and no official patches have been released at the time of this analysis. The issue arises from improper handling of error reporting, where the system fails to sanitize or limit the detail of error messages returned to users, violating secure coding practices that recommend generic error responses to prevent information leakage.

For European organizations utilizing IBM InfoSphere Information Server 11.7, this vulnerability poses a moderate risk primarily related to confidentiality and integrity. The leakage of sensitive system information can aid attackers in crafting more effective attacks, potentially leading to unauthorized access or data breaches. Organizations in sectors with high data sensitivity, such as finance, healthcare, and government, may face increased risks if attackers exploit this information to compromise critical systems. Although the vulnerability requires authenticated access, insider threats or compromised credentials could be leveraged to exploit this flaw. The impact on availability is minimal, as the vulnerability does not directly enable denial of service or system disruption. However, the indirect consequences of a successful follow-up attack could be significant. Given the widespread use of IBM InfoSphere in data integration and analytics across European enterprises, this vulnerability could affect data processing integrity and confidentiality, undermining compliance with regulations like GDPR.

To mitigate this vulnerability, European organizations should implement the following specific measures: 1) Restrict access to IBM InfoSphere Information Server to only trusted and necessary personnel, enforcing strict authentication and authorization controls to minimize the risk of credential compromise. 2) Implement robust monitoring and logging of error messages and user activities to detect unusual access patterns or attempts to trigger detailed error responses. 3) Configure the application or underlying web server to suppress detailed error messages in production environments, replacing them with generic error notifications that do not disclose sensitive information. 4) Engage with IBM support channels to obtain any forthcoming patches or official guidance and apply updates promptly once available. 5) Conduct regular security assessments and code reviews focusing on error handling and information disclosure to identify and remediate similar issues proactively. 6) Educate developers and system administrators on secure error handling best practices to prevent recurrence. 7) Consider deploying web application firewalls (WAFs) with rules designed to detect and block requests that may trigger detailed error messages or exploit information leakage.
