Vulnerability Title
Server Side Request Forgery in GravityZone Update Server Using Null Bytes (VA-12646)
Source: CVE Program / CVE List V5
Vulnerability Description
A server-side request forgery (SSRF) vulnerability exists in the Bitdefender GravityZone Update Server when operating in Relay Mode. The HTTP proxy component on port 7074 uses a domain allowlist to restrict outbound requests, but fails to properly sanitize hostnames containing null-byte (%00) sequences. By crafting a request to a domain such as evil.com%00.bitdefender.com, an attacker can bypass the allowlist check, causing the proxy to forward requests to arbitrary external or internal systems.
