CVE-2024-12973
📋 TL;DR
This CVE describes an origin validation error in Akinsoft OctoCloud that allows HTTP response splitting attacks. Attackers can inject malicious headers into HTTP responses, potentially leading to cache poisoning, cross-site scripting, or session hijacking. This affects OctoCloud installations from version s1.09.01 up to (but not including) v1.11.01.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could poison web caches, perform cross-site scripting attacks, hijack user sessions, or redirect users to malicious sites by injecting arbitrary HTTP headers into responses.
Likely Case
Cache poisoning leading to users receiving malicious content or session hijacking through crafted responses.
If Mitigated
Limited impact with proper input validation and output encoding in place, though the vulnerability still exists at the application layer.
🎯 Exploit Status
Exploitation requires understanding of HTTP response splitting techniques and ability to craft malicious requests. No public exploit code is known at this time.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v1.11.01 or later
Vendor Advisory: https://www.usom.gov.tr/bildirim/tr-25-0203
Restart Required: No
Instructions:
1. Download OctoCloud v1.11.01 or later from official Akinsoft sources. 2. Backup current installation and configuration. 3. Install the updated version following vendor instructions. 4. Verify the update was successful.
🔧 Temporary Workarounds
Implement Web Application Firewall (WAF)
allConfigure WAF rules to detect and block HTTP response splitting attempts by filtering malicious header injection patterns.
Input Validation Filtering
allImplement strict input validation on all user-supplied data, particularly for CR and LF characters that enable header injection.
🧯 If You Can't Patch
- Isolate OctoCloud instances behind reverse proxies with strict header validation
- Implement network segmentation to limit access to OctoCloud services
🔍 How to Verify
Check if Vulnerable:
Check OctoCloud version via admin interface or configuration files. If version is between s1.09.01 and v1.11.01 (exclusive), the system is vulnerable.Check Version:
Check OctoCloud admin panel or configuration files for version informationVerify Fix Applied:
Verify version is v1.11.01 or later. Test with controlled HTTP response splitting attempts to confirm mitigation.📡 Detection & Monitoring
Log Indicators:
- Unusual HTTP requests containing CR/LF sequences in headers or parameters
- Multiple failed attempts with malformed headers
- Unexpected HTTP response headers in logs
Network Indicators:
- HTTP requests with encoded newline characters (%0D%0A, %0A, %0D)
- Responses with multiple Content-Type or Location headers
- Abnormal cache behavior patterns
SIEM Query:
http.request.uri contains "%0D%0A" OR http.request.uri contains "%0A" OR http.request.uri contains "%0D"
