CVE-2025-67279
📋 TL;DR
This vulnerability in TIM BPM Suite & TIM FLOW allows remote attackers to escalate privileges by exploiting weak MD5 password hashes stored by the application. Organizations using affected versions of these business process management tools are at risk of unauthorized administrative access.
💻 Affected Systems
- TIM BPM Suite
- TIM FLOW
📦 What is this software?
Tim Flow by Tim Solutions
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain administrative control over the BPM system, potentially accessing sensitive business processes, data, and connected systems.
Likely Case
Attackers with initial access can escalate privileges to perform unauthorized actions within the application.
If Mitigated
With proper network segmentation and access controls, impact is limited to the application layer only.
🎯 Exploit Status
Requires initial access to the application but MD5 hash cracking is trivial with modern hardware.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 9.1.2
Vendor Advisory: https://tim-doc.atlassian.net/wiki/spaces/eng/pages/230981636/Release+Notes
Restart Required: Yes
Instructions:
1. Download TIM BPM Suite/TIM FLOW version 9.1.2 or later from official sources. 2. Backup current installation and data. 3. Stop all TIM services. 4. Install the updated version. 5. Restart services and verify functionality.
🔧 Temporary Workarounds
Enforce Strong Password Policies
allRequire complex passwords to make MD5 hash cracking more difficult
Network Segmentation
allIsolate TIM applications from critical systems and limit network access
🧯 If You Can't Patch
- Implement multi-factor authentication for all TIM application access
- Monitor for unusual privilege escalation attempts and hash cracking activities
🔍 How to Verify
Check if Vulnerable:
Check application version in admin interface or configuration files. Versions below 9.1.2 are vulnerable.Check Version:
Check TIM application admin panel or consult application documentation for version checking.Verify Fix Applied:
Verify version is 9.1.2 or higher and check that password storage mechanism has been updated.📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts followed by successful admin access
- Unusual privilege escalation events in application logs
Network Indicators:
- Unusual authentication traffic patterns to TIM applications
- External connections attempting to access password-related endpoints
