While the cybersecurity analysts at Rapid7 marked the CVE-2023-3519 as the critical zero-day vulnerability among the three, enabling unauthenticated attackers to execute code on vulnerable Gateway systems remotely.
Since the CVE-2023-3519 is currently exploited in the wild, poses a significant risk. Due to the popularity of this product line among threat actors, Rapid7 advises immediate emergency updates instead of waiting for the regular patch cycle.
To exploit the security issue, hackers target vulnerable appliances configured as gateways (VPN virtual server, ICA Proxy, CVPN, RDP Proxy) or authentication virtual servers (AAA server).
The vulnerabilities impact the following supported versions of NetScaler ADC and NetScaler Gateway:-
