II. Public POCs for CVE-2023-6549
| # | POC Description | Source Link | Shenlong Link |
|---|---|---|---|
| 1 | 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/cves/2023/CVE-2023-6549.yaml | POC Details |
