CVE-2025-36090 is a medium-severity vulnerability identified in IBM Analytics Content Hub versions 2.0 through 2.3. The vulnerability is categorized under CWE-209, which pertains to the generation of error messages containing sensitive information. Specifically, this flaw allows a remote attacker to trigger detailed technical error messages that disclose information about the underlying application framework. Such information leakage can aid attackers in reconnaissance activities, enabling them to gather intelligence about the system's architecture, configuration, or software components. This reconnaissance can be leveraged to craft more targeted and effective attacks against the affected system. The vulnerability requires the attacker to have low privileges (PR:L) but does not require user interaction (UI:N). The attack vector is network-based (AV:N), meaning the attacker can exploit the vulnerability remotely over the network. The CVSS v3.1 base score is 4.3, reflecting a medium severity level primarily due to the limited impact on confidentiality (partial information disclosure), no impact on integrity or availability, and the requirement for some level of privilege. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that mitigation may rely on configuration changes or vendor updates once available.

For European organizations using IBM Analytics Content Hub, this vulnerability poses a moderate risk primarily related to information disclosure. The leakage of sensitive technical details can facilitate further attacks such as privilege escalation, exploitation of other vulnerabilities, or targeted phishing campaigns. Organizations in sectors with high data sensitivity, such as finance, healthcare, and government, could face increased risk if attackers use the disclosed information to compromise critical analytics infrastructure. While the vulnerability does not directly affect data integrity or availability, the reconnaissance advantage gained by attackers can lead to more severe downstream impacts. Additionally, compliance with European data protection regulations like GDPR may be impacted if sensitive system information is exposed, potentially leading to regulatory scrutiny. The remote exploitability and lack of required user interaction increase the urgency for European entities to address this vulnerability promptly.

To mitigate CVE-2025-36090 effectively, European organizations should: 1) Immediately review and harden error handling configurations in IBM Analytics Content Hub to suppress detailed error messages from being exposed to unauthorized users. This may involve disabling verbose error reporting or customizing error responses to provide generic messages. 2) Implement strict access controls and network segmentation to limit exposure of the Analytics Content Hub to trusted users and systems only, reducing the attack surface. 3) Monitor logs and network traffic for unusual access patterns or repeated error message triggers that could indicate reconnaissance attempts. 4) Stay informed about IBM’s official patches or updates addressing this vulnerability and apply them promptly once released. 5) Conduct regular security assessments and penetration testing focused on error message handling and information disclosure vectors. 6) Educate development and operations teams about secure error handling best practices to prevent similar issues in future deployments.
