CVE-2024-47516
📋 TL;DR
This vulnerability in Pagure allows remote code execution through argument injection in Git operations. Attackers can exploit this by manipulating repository history retrieval to execute arbitrary commands on the Pagure server. All Pagure instances using vulnerable versions are affected.
💻 Affected Systems
- Pagure
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Full compromise of the Pagure server allowing attacker to execute arbitrary commands with the privileges of the Pagure service account, potentially leading to data theft, system takeover, or lateral movement.
Likely Case
Remote code execution leading to unauthorized access, data exfiltration, or deployment of malware/backdoors on the Pagure instance.
If Mitigated
Limited impact if proper network segmentation, least privilege, and monitoring are in place, though RCE still poses significant risk.
🎯 Exploit Status
Exploitation requires access to manipulate Git repository operations in Pagure. The argument injection vulnerability makes exploitation relatively straightforward once access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Red Hat advisory for specific fixed versions
Vendor Advisory: https://access.redhat.com/security/cve/CVE-2024-47516
Restart Required: Yes
Instructions:
1. Check the Red Hat advisory for the specific fixed version. 2. Update Pagure to the patched version. 3. Restart the Pagure service. 4. Verify the fix is applied.
🔧 Temporary Workarounds
Disable Git repository functionality
linuxTemporarily disable Git repository operations in Pagure to prevent exploitation
# Modify Pagure configuration to disable Git repo functionality
# Specific commands depend on your Pagure deployment method
Network segmentation
linuxRestrict network access to Pagure instances
# Use firewall rules to limit access
iptables -A INPUT -p tcp --dport <pagure_port> -s <trusted_ips> -j ACCEPT
iptables -A INPUT -p tcp --dport <pagure_port> -j DROP
🧯 If You Can't Patch
- Implement strict access controls to limit who can perform Git operations in Pagure
- Deploy network segmentation and monitoring to detect exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Check your Pagure version against the vulnerable versions listed in the Red Hat advisoryCheck Version:
# Check Pagure version - method depends on installation: rpm -q pagure or check package managerVerify Fix Applied:
Verify you're running a patched version of Pagure and test that Git repository operations work without allowing argument injection📡 Detection & Monitoring
Log Indicators:
- Unusual Git command executions in Pagure logs
- Suspicious process spawns from Pagure service account
- Unexpected command-line arguments in Git operations
Network Indicators:
- Unusual outbound connections from Pagure server
- Traffic patterns indicating exploitation attempts
SIEM Query:
Example: source="pagure.log" AND ("git" AND "exec" OR "spawn" OR suspicious arguments)
