18 The vulnerability would enable an attacker to remotely obtain sensitive information from a NetScaler appliance configured as a Gateway or AAA virtual server via a very commonly connected Web interface, and without requiring authentication. This bug is nearly identical to the Citrix Bleed vulnerability (CVE-2023-4966), except it is less likely to return highly sensitive information to an attacker. https://github.com/projectdiscovery/nuclei-templates/blob/main/http/vulnerabilities/citrix/citrix-oob-memory-read.yaml POC详情
