CVE-2024-8049
📋 TL;DR
This vulnerability in Progress Telerik Document Processing Libraries allows attackers to cause denial of service by submitting specially crafted documents with unsupported features. When processed, these documents trigger excessive resource consumption, making the application unavailable. Organizations using affected Telerik components in web applications or document processing systems are impacted.

- Progress Telerik Document Processing Libraries
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete application unavailability due to resource exhaustion, potentially affecting multiple services if the vulnerable component is shared across applications.
Likely Case
Application denial of service affecting document processing functionality, with potential cascading effects on dependent services.
If Mitigated
Limited impact with proper input validation and resource monitoring in place, though some performance degradation may occur.
🎯 Exploit Status
Exploitation requires only the ability to submit documents to vulnerable endpoints, making it accessible to attackers with minimal technical skill.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2024 Q4 (2024.4.1106) or later
Vendor Advisory: https://docs.telerik.com/devtools/document-processing/knowledge-base/excessive-allocation-cve-2024-8049
Restart Required: Yes
Instructions:
1. Update all Telerik Document Processing Libraries to version 2024.4.1106 or later. 2. Rebuild and redeploy applications using the updated libraries. 3. Restart application services to ensure new versions are loaded.
🔧 Temporary Workarounds
Implement document validation
allAdd server-side validation to reject documents with unsupported features before processing
Resource limiting
linuxConfigure application or container resource limits to prevent complete exhaustion
docker run --memory=512m --cpus=1 your_app_container
🧯 If You Can't Patch
- Implement strict input validation for document uploads, rejecting files with unexpected features
- Deploy rate limiting and monitoring on document processing endpoints to detect and block abuse
🔍 How to Verify
Check if Vulnerable:
Check application dependencies for Telerik Document Processing Libraries version below 2024.4.1106Check Version:
Check package manager (nuget, npm, etc.) or assembly version in deployed applicationVerify Fix Applied:
Confirm Telerik Document Processing Libraries version is 2024.4.1106 or higher in application dependencies📡 Detection & Monitoring
Log Indicators:
- High CPU/memory usage spikes during document processing
- Application crashes or hangs when processing documents
- Repeated failed document import attempts
Network Indicators:
- Unusually large document uploads to processing endpoints
- High volume of document uploads from single sources
