Denial of service via malformed HTTP/2 requests in NetScaler ADC and NetScaler Gateway if HTTP/2 is enabled in HTTP Profile and associated with the virtual server (of type LB, CS, VPN) or the service configured on NetScaler
Update NetScaler/ADC to 72.61; NetScaler/Gateway to 72.61 if you use the affected versions. Test the change in a non-production environment first.
Local check
hol-guard supply-chain scanDenial of service via malformed HTTP/2 requests affects NetScaler/ADC (generic), NetScaler/Gateway (generic). Severity is high. Denial of service via malformed HTTP/2 requests in NetScaler ADC and NetScaler Gateway if HTTP/2 is enabled in HTTP Profile and associated with the virtual server (of type LB, CS, VPN) or the service configured on NetScaler
AI coding agents often install or upgrade packages automatically in generic. A high vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
