CVE-2025-53619
📋 TL;DR
An out-of-bounds read vulnerability in Grassroot DICOM's JPEGBITSCodec::InternalCode function allows attackers to leak sensitive information by providing specially crafted DICOM files. This affects systems using Grassroot DICOM 3.024 for medical imaging processing. The vulnerability can be exploited without authentication to read memory contents.
💻 Affected Systems
- Grassroot DICOM
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Sensitive patient data, system memory contents, or authentication credentials could be exfiltrated from medical imaging systems, potentially violating HIPAA/medical privacy regulations.
Likely Case
Information disclosure of medical image metadata, partial memory contents, or system information that could aid further attacks.
If Mitigated
Limited information leakage with proper input validation and memory protection controls in place.
🎯 Exploit Status
Exploitation requires crafting a malicious DICOM file but doesn't require authentication if file processing is accessible.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://talosintelligence.com/vulnerability_reports/TALOS-2025-2210
Restart Required: No
Instructions:
1. Monitor Grassroot DICOM vendor for security updates. 2. Check if newer versions address CWE-119 issues. 3. Apply patches when available from official sources.
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict validation of DICOM files before processing with Grassroot DICOM library
Memory Protection
allEnable ASLR and DEP/Control Flow Guard on systems using the vulnerable library
# Windows: Enable DEP via System Properties > Advanced > Performance Settings
# Linux: Check ASLR status: sysctl kernel.randomize_va_space
🧯 If You Can't Patch
- Isolate systems using Grassroot DICOM from untrusted networks and limit file upload sources
- Implement application-level firewalls to monitor and block suspicious DICOM file processing patterns
🔍 How to Verify
Check if Vulnerable:
Check if Grassroot DICOM version 3.024 is installed and used for DICOM file processingCheck Version:
# Check library version in application dependencies or package managerVerify Fix Applied:
Verify updated version is installed and test with known safe DICOM files📡 Detection & Monitoring
Log Indicators:
- Multiple failed DICOM file parsing attempts
- Unusual memory access patterns in application logs
- Large out-of-bounds read errors
Network Indicators:
- Unusual DICOM file uploads to medical imaging systems
- Multiple failed C-STORE requests with malformed files
