CVE-2025-67282
📋 TL;DR
Multiple authorization bypass vulnerabilities in TIM BPM Suite/TIM FLOW allow low-privileged users to access sensitive data and modify restricted content. This affects all users of these workflow automation platforms up to version 9.1.2. Attackers can download password hashes, access other users' work items, modify workflows, change application logos, and manipulate user profiles.
💻 Affected Systems

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of user accounts through password hash cracking leading to privilege escalation, unauthorized workflow modifications causing business process disruption, and data exfiltration of sensitive work items.
Likely Case
Unauthorized access to sensitive work items and user data, potential credential theft through password hash exposure, and unauthorized modifications to workflows and application settings.
If Mitigated
Limited impact with proper network segmentation, strong authentication controls, and monitoring of unusual user activities.
🎯 Exploit Status
Exploitation requires low-privileged user access. The vulnerabilities are in authorization logic, making exploitation straightforward once authenticated.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 9.1.3 or later
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 9.1.3 or later from official vendor sources. 2. Backup current configuration and data. 3. Stop the application services. 4. Install the updated version. 5. Restart application services. 6. Verify functionality.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to TIM applications to only trusted users and systems
Enhanced Monitoring
allImplement detailed logging and monitoring for authorization failures and unusual user activities
🧯 If You Can't Patch
- Implement strict network segmentation and firewall rules to limit access to TIM applications
- Enforce strong authentication mechanisms and regularly audit user permissions and activities
🔍 How to Verify
Check if Vulnerable:
Check application version in admin interface or configuration files. Versions 9.1.2 and earlier are vulnerable.Check Version:
Check application admin panel or configuration files for version informationVerify Fix Applied:
Verify version is 9.1.3 or later and test authorization controls for proper enforcement.📡 Detection & Monitoring
Log Indicators:
- Multiple authorization failures from same user
- Unusual access patterns to user management endpoints
- Unexpected modifications to workflow configurations
Network Indicators:
- Unusual API calls to user/profile endpoints
- Multiple requests to password/hash related endpoints
