AI-suggested

Organizations should immediately assess their IBM InfoSphere Information Server deployments to identify affected versions (11.7.0.0 through 11.7.1.6). In the absence of an official patch, implement strict input validation and sanitization on HTTP headers at the network perimeter using web application firewalls (WAFs) or reverse proxies to block malicious HOST header values. Monitor HTTP traffic for anomalous header patterns indicative of injection attempts. Restrict access to the InfoSphere server to trusted networks and enforce HTTPS to protect header integrity during transmission. Regularly review and update security policies related to HTTP header handling. Engage with IBM support for updates on patches or hotfixes and apply them promptly once available. Conduct security awareness training for administrators to recognize signs of exploitation and respond swiftly. Finally, implement comprehensive logging and alerting to detect and investigate suspicious activities related to HTTP header manipulation.

Description

IBM InfoSphere Information Server 11.7.0.0 through 11.7.1.6 is vulnerable to HTTP header injection, caused by improper validation of input by the HOST headers. This could allow an attacker to conduct various attacks against the vulnerable system, including cross-site scripting, cache poisoning or session hijacking.
