CVE-2025-2667 is a vulnerability identified in IBM Sterling B2B Integrator and IBM Sterling File Gateway, specifically affecting versions 6.0.0.0 through 6.1.2.7_1 and 6.2.0.0 through 6.2.0.4. The vulnerability is categorized under CWE-497, which pertains to the exposure of sensitive system information to an unauthorized control sphere. In this case, the flaw allows a privileged user to access sensitive system information about the server that should not be disclosed. Although the user must already have elevated privileges (as indicated by the CVSS vector's PR:H), the leakage of such information can facilitate further attacks by providing attackers with insights into system configurations, software versions, or other internal details that could be leveraged to identify additional vulnerabilities or misconfigurations. The CVSS v3.1 base score is 2.7, reflecting a low severity primarily because exploitation requires high privileges and does not impact system integrity or availability. No user interaction is needed, and the attack vector is network-based, meaning the privileged user could exploit this remotely if they have network access. No known exploits are reported in the wild, and no patches are currently linked, suggesting that mitigation may rely on vendor updates or configuration changes. The vulnerability does not directly allow unauthorized access but exposes sensitive information within an already privileged context, which could be a stepping stone for privilege escalation or lateral movement within an enterprise environment.

For European organizations, the impact of CVE-2025-2667 is primarily related to information disclosure within environments using IBM Sterling B2B Integrator or Sterling File Gateway. These products are commonly used for secure B2B data exchange and file transfers, often handling sensitive business transactions and supply chain communications. Exposure of system information to privileged users could aid internal threat actors or compromised accounts in mapping the environment and identifying further attack vectors, potentially leading to more severe breaches. While the vulnerability itself does not directly compromise confidentiality or availability, it lowers the barrier for attackers to conduct targeted attacks or escalate privileges. Organizations in sectors with high reliance on B2B integrations, such as manufacturing, logistics, finance, and retail, may face increased risk if internal controls over privileged accounts are weak. Additionally, given the network attack vector, if privileged credentials are compromised externally, attackers could exploit this vulnerability remotely. The low CVSS score indicates limited immediate risk, but the strategic importance of the affected systems in critical business processes means that even minor information leaks can have cascading effects on operational security and compliance with data protection regulations like GDPR.

To mitigate CVE-2025-2667 effectively, European organizations should implement the following specific measures: 1) Restrict and monitor privileged user access rigorously, employing the principle of least privilege and ensuring that only necessary personnel have elevated rights within IBM Sterling environments. 2) Conduct regular audits of privileged account activities and implement anomaly detection to identify unusual access patterns that could indicate exploitation attempts. 3) Apply any available vendor patches or updates promptly once released; in the absence of patches, consult IBM support for recommended configuration changes or workarounds to limit sensitive information exposure. 4) Harden network access controls to limit exposure of IBM Sterling servers to trusted networks and VPNs, reducing the attack surface for remote exploitation. 5) Employ encryption and secure logging practices to protect sensitive data and audit trails, ensuring that any disclosed information is minimized and monitored. 6) Integrate IBM Sterling systems into broader enterprise security monitoring and incident response workflows to quickly detect and respond to potential misuse of privileged accounts. 7) Educate privileged users on security best practices and the risks associated with information disclosure vulnerabilities to reduce inadvertent exploitation.
