CriticalCVSS 9.1Summary
IBM Common Licensing Agent 9.0, 9.0.0.1, 9.0.0.2 and ART 9.0, 9.0.0.1, 9.0.0.2 allow a remote attacker to redirect users to an arbitrary domain due to improper validation of the HTTP Host header.
Risk Assessment
An attacker could exploit this to conduct phishing or redirect users to malicious sites, potentially leading to credential theft.
Recommendation
Upgrade IBM Common Licensing Agent and ART to a patched version and enforce Host header validation at the proxy level.
