CVE-2022-46973
📋 TL;DR
CVE-2022-46973 is a Server-Side Request Forgery (SSRF) vulnerability in Report v0.9.8.6 that allows attackers to make unauthorized requests from the vulnerable server to internal or external systems. This affects any organization using the vulnerable version of Report software. Attackers can potentially access internal services, perform port scanning, or interact with cloud metadata services.

Aj Report by Anji Plus
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of internal network resources, data exfiltration from internal services, cloud metadata exploitation leading to privilege escalation, and lateral movement within the network.
Likely Case
Unauthorized access to internal HTTP services, port scanning of internal networks, and potential data leakage from internal APIs or services.
If Mitigated
Limited to external resource interaction only, with no access to internal systems due to proper network segmentation and egress filtering.
🎯 Exploit Status
SSRF vulnerabilities are commonly exploited and weaponized. The public GitHub references demonstrate the vulnerability exists.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v0.9.8.7 or later
Vendor Advisory: https://github.com/anji-plus/report/issues/15
Restart Required: Yes
Instructions:
1. Backup current configuration and data. 2. Download the latest version from the official repository. 3. Stop the Report service. 4. Replace the vulnerable version with the patched version. 5. Restart the Report service. 6. Verify the service is running correctly.
🔧 Temporary Workarounds
Network Segmentation and Egress Filtering
linuxImplement network controls to restrict outbound connections from the Report server to only necessary external services.
iptables -A OUTPUT -p tcp --dport 80 -j ACCEPT
iptables -A OUTPUT -p tcp --dport 443 -j ACCEPT
iptables -A OUTPUT -j DROP
Input Validation and URL Whitelisting
allImplement input validation to reject URLs pointing to internal IP ranges (RFC 1918, localhost, etc.) and only allow specific whitelisted domains.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate the Report server from sensitive internal systems
- Deploy a web application firewall (WAF) with SSRF protection rules to block malicious requests
🔍 How to Verify
Check if Vulnerable:
Check the Report version by examining the application files or configuration. If version is exactly v0.9.8.6, the system is vulnerable.Check Version:
Check the application's version file or configuration, typically found in the installation directory.Verify Fix Applied:
After patching, verify the version shows v0.9.8.7 or later. Test SSRF functionality with controlled test cases to ensure internal requests are blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual outbound HTTP requests from the Report server to internal IP addresses
- Requests to cloud metadata endpoints (169.254.169.254, etc.)
- Multiple failed connection attempts to various internal ports
Network Indicators:
- Unexpected HTTP traffic from Report server to internal services
- Port scanning patterns originating from the Report server
- Requests to restricted internal endpoints
