CVE-2025-62687
📋 TL;DR
A cross-site request forgery (CSRF) vulnerability in LogStare Collector allows attackers to trick authenticated users into performing unintended operations. When logged-in users visit malicious web pages, attackers can force actions like configuration changes or data deletion. This affects all LogStare Collector users with web interface access.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through configuration changes leading to data loss, service disruption, or secondary attacks via modified settings.
Likely Case
Unauthorized configuration changes, data manipulation, or service disruption through crafted requests.
If Mitigated
Limited impact with proper CSRF protections, though some risk remains if other vulnerabilities exist.
🎯 Exploit Status
Exploitation requires user authentication but is trivial with basic web development skills; CSRF attacks are well-understood and easily weaponized.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 3.2.1
Vendor Advisory: https://www.logstare.com/vulnerability/2025-001/
Restart Required: Yes

1. Download LogStare Collector 3.2.1 from official vendor site. 2. Stop the collector service. 3. Backup configuration files. 4. Install the update. 5. Restart the service. 6. Verify functionality.
🔧 Temporary Workarounds
CSRF Token Implementation
allAdd custom CSRF tokens to all state-changing requests if patching isn't immediately possible.
# Requires custom middleware implementation; no single command
SameSite Cookie Enforcement
allConfigure session cookies with SameSite=Strict attribute to limit cross-origin requests.
# Set in web server configuration or application settings
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to detect and block CSRF patterns
- Restrict web interface access to trusted networks only using firewall rules
🔍 How to Verify
Check if Vulnerable:
Check if version is below 3.2.1 via web interface or configuration file; test for missing CSRF tokens in POST requests.Check Version:
logstare-collector --versionVerify Fix Applied:
Verify version is 3.2.1 or higher; test that all state-changing requests include CSRF tokens.📡 Detection & Monitoring
Log Indicators:
- Unexpected configuration changes
- Multiple failed authentication attempts followed by successful state changes
- Requests missing expected CSRF tokens
Network Indicators:
- HTTP POST requests from unexpected referrers
- State-changing requests without corresponding GET requests
