Q4What can hackers do? (Privileges/Data)
๐ป **Attacker Capabilities**:
1. **Bypass Authentication**: Gain access without valid credentials. ๐
2. **SSRF Attacks**: Force the server to make requests to internal or external resources. ๐
3.โฆ
๐ **Public Exploit**: **YES**. A Nuclei template exists on GitHub (projectdiscovery/nuclei-templates). It detects vulnerability by triggering **external DNS lookups** via the `SERVER` parameter.โฆ
