CVE-2025-53075
📋 TL;DR
CVE-2025-53075 is a path traversal vulnerability in Samsung's rLottie animation library that allows attackers to read arbitrary files on the system. This affects any application using rLottie V0.2 to process malicious animation files. The vulnerability stems from improper input validation when handling file paths.
💻 Affected Systems
- Samsung rLottie
- Applications embedding rLottie library
📦 What is this software?
Rlottie by Samsung
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through arbitrary file read leading to credential theft, sensitive data exposure, and potential privilege escalation.
Likely Case
Unauthorized access to sensitive files including configuration files, credentials, and user data from applications using rLottie.
If Mitigated
Limited impact with proper file system permissions and sandboxing, though sensitive data may still be exposed.
🎯 Exploit Status
Exploitation requires providing a malicious animation file to the vulnerable application. No authentication needed if file processing is exposed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Fixed in commit 6b8c5a7 and later versions
Vendor Advisory: https://github.com/Samsung/rlottie/pull/571
Restart Required: Yes
Instructions:
1. Update rLottie to latest version from GitHub. 2. Rebuild applications using rLottie. 3. Restart affected services. 4. Verify fix with test cases.
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict validation on animation file paths before passing to rLottie
# Implement path sanitization in application code
# Example: validate file paths don't contain ../ or absolute paths
File Access Restrictions
linuxRun rLottie in sandboxed environment with restricted file system access
# Use containerization or chroot
# Example: docker run --read-only -v /safe/path:/data
🧯 If You Can't Patch
- Disable rLottie animation processing in affected applications
- Implement network segmentation to isolate systems using vulnerable rLottie version
🔍 How to Verify
Check if Vulnerable:
Check if application uses rLottie V0.2 via dependency check or version queryCheck Version:
Check rLottie version in build configuration or runtime library infoVerify Fix Applied:
Test with known malicious animation files to ensure path traversal is blocked📡 Detection & Monitoring
Log Indicators:
- Unusual file access patterns from animation processing
- Failed path traversal attempts in application logs
Network Indicators:
- Unexpected outbound data transfers after animation file upload
SIEM Query:
source="application_logs" AND ("../" OR "/etc/" OR "/root/") AND "animation" OR "rlottie"
