CVE-2025-14150 Overview
CVE-2025-14150 is an information disclosure vulnerability affecting IBM webMethods Integration (on-premises) - Integration Server. The vulnerability allows sensitive user information to be disclosed through server responses, potentially exposing confidential data to attackers with low-privilege network access.
This vulnerability is classified as CWE-497 (Exposure of Sensitive System Information to an Unauthorized Control Sphere), indicating that the application improperly exposes sensitive system or user data in responses that can be accessed by unauthorized parties.
Critical Impact
Authenticated attackers with network access can extract sensitive user information from server responses, potentially leading to further attacks or unauthorized access to confidential data.
Affected Products
- IBM webMethods Integration (on-premises) - Integration Server 10.15
- IBM webMethods Integration Server versions through IS_10.15_Core_Fix2411.1
- IBM webMethods Integration Server versions up to IS_11.1_Core_Fix8

Technical Details for CVE-2025-14150
Vulnerability Analysis
The vulnerability exists within IBM webMethods Integration Server, where the application inadvertently includes sensitive user information in server responses. This information disclosure flaw requires network access and low-level authentication to exploit, but once exploited, it provides high impact to data confidentiality.
The vulnerability does not require user interaction to exploit, and while it affects confidentiality significantly, it does not directly impact system integrity or availability. The attack can be conducted remotely over the network, making it accessible to any authenticated user who can reach the vulnerable service.
Root Cause
The root cause is improper handling of sensitive information in server responses (CWE-497). The IBM webMethods Integration Server fails to adequately sanitize or restrict sensitive user data from being included in responses sent to clients. This exposure of system information to unauthorized control spheres allows authenticated attackers to harvest user data that should remain protected.
Attack Vector
The attack is network-based and requires low-level privileges to execute. An attacker with valid credentials can send requests to the Integration Server and receive responses containing sensitive user information that should not be disclosed. The attack does not require any user interaction and can be automated once the attacker has network access and authentication credentials.
The exploitation mechanism involves:
- Establishing a network connection to the vulnerable IBM webMethods Integration Server
- Authenticating with low-privilege credentials
- Issuing requests that trigger responses containing sensitive user information
- Extracting and analyzing the disclosed data for further exploitation
For technical details on the vulnerability mechanism, refer to the IBM Security Advisory.
Detection Methods for CVE-2025-14150
Indicators of Compromise
- Unusual patterns of API requests to Integration Server endpoints from authenticated users
- Increased volume of server response data being transmitted to specific client addresses
- Authentication logs showing repeated access by low-privilege accounts to sensitive endpoints
- Network traffic analysis revealing sensitive data patterns in server responses
Detection Strategies
- Monitor Integration Server access logs for anomalous request patterns targeting user-related endpoints
- Implement network traffic inspection to identify potential data exfiltration through server responses
- Deploy intrusion detection rules to flag responses containing unexpected sensitive data patterns
- Review authentication logs for accounts making excessive requests to information-rich endpoints
Monitoring Recommendations
- Enable detailed logging on IBM webMethods Integration Server for all authentication and data access events
- Configure SIEM rules to correlate multiple requests from the same authenticated session to sensitive endpoints
- Implement baseline analysis for normal server response sizes and flag anomalies
- Monitor for known exploitation patterns associated with information disclosure vulnerabilities
How to Mitigate CVE-2025-14150
Immediate Actions Required
- Apply the latest security patches from IBM for webMethods Integration Server immediately
- Review and restrict network access to the Integration Server to only necessary clients
- Audit user accounts with access to the Integration Server and remove unnecessary privileges
- Enable enhanced logging to detect potential exploitation attempts
Patch Information
IBM has released security updates to address this vulnerability. Organizations running affected versions (IS_10.15 through IS_10.15_Core_Fix2411.1 to IS_11.1_Core_Fix8) should apply the latest available patches immediately.
For detailed patch information and download links, consult the IBM Security Advisory.
Workarounds
- Implement network segmentation to limit access to the Integration Server from untrusted networks
- Apply strict access controls to restrict which authenticated users can access sensitive endpoints
- Deploy a Web Application Firewall (WAF) to filter and monitor traffic to the Integration Server
- Consider implementing additional response filtering at the reverse proxy level to sanitize sensitive data
For environments where immediate patching is not feasible, IBM recommends consulting the security advisory for vendor-approved temporary mitigations while scheduling patch deployment.
