CVE-2025-71001
📋 TL;DR
A segmentation violation vulnerability in OneFlow's flow.column_stack component allows attackers to cause Denial of Service (DoS) through crafted input. This affects OneFlow v0.9.0 users who process untrusted data with the vulnerable function. The vulnerability can crash the application, disrupting services.
💻 Affected Systems
- OneFlow
📦 What is this software?
Oneflow by Oneflow
⚠️ Risk & Real-World Impact
Worst Case
Complete service disruption through application crashes, potentially affecting dependent systems and causing extended downtime.
Likely Case
Intermittent application crashes when processing malicious inputs, leading to partial service degradation.
If Mitigated
Minimal impact with proper input validation and error handling in place.
🎯 Exploit Status
Exploitation requires sending crafted input to the vulnerable function, which is straightforward for attackers with access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://github.com/Oneflow-Inc/oneflow/issues/10658
Restart Required: Yes
Instructions:
1. Monitor the GitHub issue for patches. 2. Upgrade to a fixed version when available. 3. Restart affected services after patching.
🔧 Temporary Workarounds
Input Validation
allImplement strict input validation for flow.column_stack inputs to reject malformed data.
Error Handling
allAdd robust error handling around flow.column_stack calls to prevent crashes from propagating.
🧯 If You Can't Patch
- Restrict access to systems using flow.column_stack to trusted users only.
- Implement network segmentation to isolate vulnerable systems from untrusted networks.
🔍 How to Verify
Check if Vulnerable:
Check if OneFlow version is 0.9.0 and if flow.column_stack is used in your codebase.Check Version:
python -c "import oneflow; print(oneflow.__version__)"Verify Fix Applied:
Verify the OneFlow version is updated beyond 0.9.0 when a patch is released.📡 Detection & Monitoring
Log Indicators:
- Segmentation fault errors
- Application crash logs
- Unexpected termination of OneFlow processes
Network Indicators:
- Unusual input patterns to services using flow.column_stack
SIEM Query:
source="application.logs" AND ("segmentation fault" OR "crash" OR "SIGSEGV") AND process="oneflow"
