CVE-2025-7775 is a critical memory overflow vulnerability in Citrix NetScaler ADC and NetScaler Gateway that can lead to remote code execution or denial of service. The flaw affects supported NetScaler branches in specific deployment modes rather than all default installations. Exposed configurations include appliances configured as Gateway services such as VPN virtual server, ICA Proxy, CVPN, or RDP Proxy, as well as AAA virtual servers. It also affects certain load-balancing virtual server deployments of type HTTP, SSL, or HTTP_QUIC when bound to IPv6 services, IPv6 service groups, DBS IPv6 services, or DBS IPv6 service groups, and cache redirection virtual servers of type HDX. The vulnerability is described as a memory overflow condition and has been reported as exploitable by unauthenticated remote attackers on affected appliances. Citrix stated that exploitation had been observed against unmitigated devices prior to or at disclosure.
