CVE-2024-2975
📋 TL;DR
CVE-2024-2975 is a race condition vulnerability in Octopus Deploy that allows local privilege escalation. Attackers can exploit timing issues in certain configurations to gain elevated privileges. This affects Octopus Deploy Server installations with specific configuration settings.
💻 Affected Systems
- Octopus Deploy Server
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise where an attacker gains administrative control over the Octopus Deploy Server, potentially accessing sensitive deployment secrets and infrastructure credentials.
Likely Case
Privilege escalation allowing attackers to modify deployment configurations, access protected resources, or execute arbitrary code within the Octopus Deploy context.
If Mitigated
Limited impact with proper access controls and monitoring, though the vulnerability still presents a security risk that should be patched.
🎯 Exploit Status
Exploitation requires understanding of race conditions and timing attacks. Requires authenticated access to trigger the vulnerable code path.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2024.1 and later
Vendor Advisory: https://advisories.octopus.com/post/2024/sa2024-01/
Restart Required: Yes
Instructions:
1. Backup your Octopus Deploy configuration and database. 2. Download Octopus Deploy 2024.1 or later from the official website. 3. Run the installer and follow upgrade instructions. 4. Restart the Octopus Deploy service. 5. Verify the upgrade completed successfully.
🔧 Temporary Workarounds
Restrict Access Controls
allLimit user permissions and implement principle of least privilege to reduce attack surface
Network Segmentation
allIsolate Octopus Deploy Server from other critical systems to limit lateral movement
🧯 If You Can't Patch
- Implement strict access controls and audit all user permissions
- Monitor for unusual privilege escalation attempts and implement enhanced logging
🔍 How to Verify
Check if Vulnerable:
Check Octopus Deploy version in Administration → Configuration → About. If version is below 2024.1, the system is vulnerable.Check Version:
On Windows: Get-ItemProperty -Path 'HKLM:\SOFTWARE\Octopus\OctopusServer' -Name 'Version' | Select-Object VersionVerify Fix Applied:
After upgrading, verify version shows 2024.1 or later in Administration → Configuration → About.📡 Detection & Monitoring
Log Indicators:
- Unusual privilege escalation attempts
- Multiple rapid authentication requests
- Unexpected permission changes
Network Indicators:
- Multiple rapid API calls to privilege-related endpoints
- Unusual authentication patterns
