CVE-2025-2670 is a medium-severity vulnerability identified in IBM OpenPages version 9.0, a governance, risk, and compliance (GRC) management platform widely used by enterprises for regulatory compliance and risk management. The vulnerability arises from insufficient security controls on certain REST API endpoints related to the workflow feature of OpenPages. Specifically, an authenticated user with legitimate access privileges can exploit these endpoints to disclose sensitive system information concerning workflow configurations and internal states. This exposure falls under CWE-497, which pertains to the exposure of sensitive system information to an unauthorized control sphere. Although the attacker must be authenticated, the vulnerability does not require user interaction beyond authentication, and the attack vector is network-based (AV:N). The CVSS v3.1 base score is 4.3, reflecting a medium severity primarily due to the limited impact on confidentiality (partial information disclosure), no impact on integrity or availability, and the requirement for authentication. The exposed information could potentially aid an attacker in further reconnaissance or facilitate more targeted attacks by revealing internal workflow logic or configuration details that were not intended for broad visibility. No known exploits are currently reported in the wild, and no patches have been published at the time of this analysis. The vulnerability's scope is limited to IBM OpenPages 9.0 installations that utilize the affected workflow REST endpoints and have users with authenticated access, which typically includes internal users or trusted third parties.

For European organizations, the impact of this vulnerability can be significant depending on the sensitivity of the workflow configurations and internal states exposed. Since IBM OpenPages is often deployed in financial institutions, insurance companies, and large enterprises for compliance and risk management, unauthorized disclosure of workflow details could reveal internal process logic, approval chains, or risk assessment criteria. This information leakage could be leveraged by malicious insiders or external attackers who have gained authenticated access to map out internal controls, identify weaknesses, or craft social engineering attacks targeting key personnel. While the vulnerability does not directly compromise data integrity or availability, the confidentiality breach could undermine trust in compliance processes and potentially expose organizations to regulatory scrutiny if sensitive operational details are leaked. Moreover, the vulnerability could facilitate lateral movement within the network if attackers use the disclosed information to escalate privileges or bypass controls. Given the GDPR and other stringent data protection regulations in Europe, even partial exposure of sensitive system information can have legal and reputational consequences.

To mitigate this vulnerability effectively, European organizations should: 1) Restrict access to IBM OpenPages workflow REST endpoints strictly to users with a clear business need and enforce the principle of least privilege to minimize the number of authenticated users who can access these endpoints. 2) Implement strong authentication mechanisms, such as multi-factor authentication (MFA), to reduce the risk of compromised credentials being used to exploit this vulnerability. 3) Monitor and audit access logs for unusual or unauthorized access patterns to the workflow-related REST endpoints, enabling early detection of potential exploitation attempts. 4) Apply network segmentation and firewall rules to limit exposure of the OpenPages management interfaces to trusted internal networks only. 5) Engage with IBM support or security advisories to obtain patches or updates as soon as they become available and prioritize their deployment. 6) Conduct internal security assessments and penetration testing focused on the OpenPages environment to identify and remediate any additional weaknesses in workflow configurations or API security. 7) Educate users with access about the sensitivity of workflow information and enforce strict operational security policies to prevent inadvertent information leakage.
