CVE-2025-14290 Overview
CVE-2025-14290 is a Server-Side Request Forgery (SSRF) vulnerability [CWE-918] affecting IBM webMethods Integration (on-prem) Integration Server. The flaw impacts versions 10.15 through IS_10.15_Core_Fix2611.1 and IS_11.1_Core_Fix10. An authenticated attacker can abuse the server to issue unauthorized HTTP requests to internal or external systems. This can enable internal network enumeration and pivot attacks against services not directly reachable from the internet.
Critical Impact
An authenticated attacker can leverage the Integration Server to send forged requests, exposing internal services and enabling reconnaissance of otherwise unreachable network resources.

Technical Details for CVE-2025-14290
Vulnerability Analysis
The vulnerability resides in request-handling logic within IBM webMethods Integration Server. The product does not adequately validate or restrict URLs used in server-initiated requests. An authenticated user can supply a crafted destination, causing the server to issue requests on their behalf. Because the server typically operates within a privileged network segment, these forged requests can reach internal services, metadata endpoints, or administrative interfaces that are not exposed externally.
The impact aligns with classic SSRF outcomes: limited confidentiality loss through information disclosure and limited integrity loss through unauthorized actions on reachable services. Authentication is required, which reduces the attacker pool but does not eliminate risk from compromised accounts, insider threats, or credential-stuffing scenarios.
Root Cause
The root cause is insufficient validation of user-controlled input that influences outbound HTTP request destinations. The application accepts destination URLs or host parameters without enforcing an allowlist of permitted targets or blocking access to internal address ranges such as 127.0.0.0/8, 10.0.0.0/8, 169.254.169.254, and other private network blocks.
Attack Vector
The attack is network-based and requires low privileges with no user interaction. An authenticated attacker submits crafted input through an integration endpoint or service definition that triggers the server to make an outbound request to a target of the attacker's choosing. The attacker can then enumerate internal hosts, scan ports by observing response timing and error differences, or interact with internal HTTP APIs.
No verified proof-of-concept code is publicly available for this vulnerability. Refer to the IBM Support Page for vendor-specific technical details.
Detection Methods for CVE-2025-14290
Indicators of Compromise
- Outbound connections from the Integration Server to internal IP ranges or cloud metadata endpoints such as 169.254.169.254 that do not match documented integration flows.
- Unexpected HTTP requests originating from the Integration Server process to non-standard internal ports.
- Repeated outbound connection attempts to sequential internal IPs indicative of network scanning behavior.
Detection Strategies
- Inspect Integration Server access logs for authenticated sessions submitting unusual URL parameters or hostnames.
- Correlate authenticated user activity with outbound network connections to identify users triggering anomalous server-initiated requests.
- Deploy network detection rules that flag outbound traffic from the Integration Server host to RFC1918 ranges outside the documented integration scope.
Monitoring Recommendations
- Forward Integration Server application logs and host network telemetry to a centralized analytics platform for behavioral baselining.
- Monitor authentication events for low-privilege accounts that suddenly generate elevated request volumes against integration endpoints.
- Alert on outbound DNS queries from the Integration Server resolving internal hostnames or cloud metadata domains.
How to Mitigate CVE-2025-14290
Immediate Actions Required
- Apply the fix referenced on the IBM Support Page for affected 10.15 and 11.1 Integration Server fix levels.
- Audit and rotate credentials for low-privilege Integration Server accounts that may have been exposed.
- Restrict egress traffic from the Integration Server to an allowlist of required external destinations.
Patch Information
IBM has published remediation guidance on the vendor advisory. Administrators should upgrade beyond IS_10.15_Core_Fix2611.1 and IS_11.1_Core_Fix10 to the patched fix level identified by IBM. Consult the IBM Support Page for exact fix package identifiers and installation steps.
Workarounds
- Place the Integration Server behind an egress proxy that enforces an allowlist of approved outbound destinations.
- Block Integration Server access to cloud instance metadata endpoints and internal management subnets using host or network firewalls.
- Review role-based access controls and remove permissions to integration features that accept user-supplied URLs for accounts that do not require them.
# Example egress restriction using iptables to block metadata endpoint access
iptables -A OUTPUT -d 169.254.169.254 -j DROP
iptables -A OUTPUT -d 10.0.0.0/8 -p tcp --dport 22 -j DROP
iptables -A OUTPUT -d 192.168.0.0/16 -p tcp --dport 3389 -j DROP
