Summary
by MITRE • 03/25/2026
IBM InfoSphere Information Server 11.7.0.0 through 11.7.1.6 is vulnerable to server-side request forgery (SSRF). This may allow an authenticated attacker to send unauthorized requests from the system, potentially leading to network enumeration or facilitating other attacks.

IBM InfoSphere Information Server version 11.7.0.0 through 11.7.1.6 contains a server-side request forgery vulnerability that represents a critical security weakness in the platform's request handling mechanisms. This vulnerability falls under the Common Weakness Enumeration category CWE-918, which specifically addresses server-side request forgery flaws that enable attackers to manipulate the target system into making unauthorized requests to internal or external resources. The flaw exists in the application's processing of user-supplied input that is used to construct HTTP requests, creating an avenue for malicious actors to exploit the system's network connectivity.
The technical implementation of this vulnerability allows an authenticated attacker to craft specially formatted requests that bypass normal access controls and force the server to initiate connections to arbitrary destinations. This occurs when the application fails to properly validate or sanitize user input that is subsequently used in HTTP request construction. The vulnerability specifically impacts the server's ability to distinguish between legitimate and malicious request targets, enabling attackers to enumerate internal network services, access restricted resources, or potentially exfiltrate sensitive data through the compromised server's network connections.
Operational impact of this vulnerability extends beyond simple network enumeration as it provides attackers with a powerful primitive for further exploitation. An attacker could leverage the SSRF capability to probe internal network infrastructure, potentially discovering additional vulnerable systems, accessing internal APIs, or even facilitating more sophisticated attacks such as credential theft or lateral movement within the network. The authenticated nature of the vulnerability means that attackers would need valid credentials to exploit it, but once compromised, the attack surface expands significantly as the malicious requests would be executed with the privileges and network access of the compromised InfoSphere Information Server instance.
Mitigation strategies for this vulnerability should focus on implementing strict input validation and sanitization mechanisms throughout the application's request processing pipeline. Organizations should consider implementing network segmentation and firewall rules to limit the server's ability to communicate with unauthorized destinations. The implementation of a robust allowlist approach for outbound connections, combined with comprehensive monitoring of network traffic patterns, can help detect and prevent unauthorized requests. Additionally, regular security assessments and vulnerability scanning should be conducted to identify potential attack vectors and ensure that the system remains protected against similar vulnerabilities. This vulnerability aligns with ATT&CK technique T1071.004 for application layer protocol: DNS and T1566 for credential access through server-side request forgery, making it a significant concern for enterprise security posture management.
