Overview
CVE-2025-36112 identifies an information disclosure vulnerability affecting IBM Sterling B2B Integrator and IBM Sterling File Gateway. This flaw could allow an unauthorized user to access sensitive server IP configuration information. Understanding this vulnerability is crucial for organizations using these platforms to ensure the confidentiality and security of their infrastructure.
Technical Details
The vulnerability, identified as CVE-2025-36112, resides in specific versions of IBM Sterling B2B Integrator and IBM Sterling File Gateway:
- IBM Sterling B2B Integrator 6.0.0.0 through 6.1.2.7
- IBM Sterling B2B Integrator 6.2.0.0 through 6.2.0.5
- IBM Sterling B2B Integrator 6.2.1.1
The precise mechanism through which the information is exposed is not fully detailed in the publicly available descriptions, however, the core issue is that server IP configuration data, normally restricted to authorized personnel, can be retrieved by unauthorized actors. This could be via unvalidated input, a flawed access control mechanism, or an overly permissive configuration.
CVSS Analysis
The vulnerability has been assigned a CVSS score of 5.3 (Medium). This score reflects the potential impact of the vulnerability, balancing the ease of exploitation and the consequences of a successful attack. While not a critical vulnerability, the potential for information disclosure warrants immediate attention and remediation. The specific CVSS vector would provide more detailed insights into exploitability and impact.
Possible Impact
The exposure of server IP configuration information can have several negative consequences:
- Reconnaissance: Attackers can use the revealed IP addresses to map out the network infrastructure, identifying potential targets for further attacks.
- Targeted Attacks: Knowledge of server IP addresses allows attackers to launch more focused and potentially successful attacks.
- Data Breach: While the IP address itself isn’t a data breach, it’s a crucial piece of information that can be used to facilitate one.
- Compromise: When coupled with other vulnerabilities or misconfigurations, the IP disclosure could allow for full server compromise.
Mitigation or Patch Steps
IBM has released fixes to address this vulnerability. Users of affected versions of IBM Sterling B2B Integrator and IBM Sterling File Gateway are strongly advised to apply the appropriate patches as soon as possible. Specific fix details can be found in the linked IBM support page.
Steps to mitigate the vulnerability include:
- Apply Patches: Upgrade to the latest fixed versions of IBM Sterling B2B Integrator or IBM Sterling File Gateway. Check the IBM support page for the latest releases.
- Review Access Controls: Audit and tighten access control configurations to ensure only authorized users can access sensitive configuration information.
- Network Segmentation: Implement network segmentation to limit the impact of a potential breach.
- Monitor for Suspicious Activity: Implement monitoring and alerting mechanisms to detect any suspicious network activity or unauthorized access attempts.
