✅ Official Fix
Patch Version: News module 5.3.3 or later
Vendor Advisory: https://typo3.org/security/advisory/typo3-ext-sa-2017-006/
Restart Required: No
Instructions:
1. Update TYPO3 News module to version 5.3.3 or later. 2. Clear TYPO3 cache. 3. Verify the patch is applied by checking module version.
🔧 Temporary Workarounds
Disable News Module
allTemporarily disable the vulnerable News module if immediate patching isn't possible.
# In TYPO3 Extension Manager, disable 'news' extension
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns targeting the News module.
# Configure WAF to block requests containing SQL injection patterns to NewsController.php endpoints
🧯 If You Can't Patch
- Implement strict network segmentation to isolate vulnerable TYPO3 instances
- Deploy database monitoring to detect unusual SQL queries from the web application
🔍 How to Verify
Check if Vulnerable:
Check if News module version is 5.3.2 or earlier in TYPO3 Extension Manager or by examining ext_emconf.php in the news extension directory.Check Version:
grep -r 'version' typo3conf/ext/news/ext_emconf.php | grep -o '[0-9]\+\.[0-9]\+\.[0-9]\+'Verify Fix Applied:
Verify News module version is 5.3.3 or later. Test vulnerable endpoints with SQL injection payloads to confirm they're blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in web server logs
- HTTP requests to NewsController.php with SQL keywords in parameters
- Multiple failed login attempts following SQL injection attempts
Network Indicators:
- HTTP POST/GET requests containing SQL injection patterns to news-related endpoints
- Unusual database connections from web server IP
SIEM Query:
source="web_logs" AND (uri="*NewsController*" AND (param="*order*" OR param="*OrderByAllowed*") AND (param="*SELECT*" OR param="*UNION*" OR param="*OR 1=1*"))
