CVE-2025-14150
📋 TL;DR
IBM webMethods Integration Server versions 10.15 through 11.1 can inadvertently expose sensitive user information in server responses. This information disclosure vulnerability affects organizations using on-premises IBM webMethods Integration for application integration. Attackers could potentially access user data that should remain confidential.
💻 Affected Systems
- IBM webMethods Integration Server
⚠️ Risk & Real-World Impact
Worst Case
Attackers could extract sensitive user information like credentials, personal data, or authentication tokens, leading to account compromise, data breaches, and regulatory violations.
Likely Case
Unauthorized access to user information that could be used for reconnaissance, targeted attacks, or combined with other vulnerabilities for more severe exploitation.
If Mitigated
Limited exposure with proper network segmentation and access controls, though sensitive data could still be exposed to authorized users who shouldn't see it.
🎯 Exploit Status
Exploitation requires access to server responses, which could be obtained through various means including legitimate access with elevated privileges.
