CVE-2025-58587
📋 TL;DR
This vulnerability allows attackers to perform brute-force attacks against authentication systems by attempting multiple login attempts without rate limiting. It affects any application or system that doesn't implement proper account lockout or throttling mechanisms. Users of affected SICK products with exposed authentication interfaces are at risk.

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain unauthorized access to administrative accounts, potentially compromising entire systems, stealing sensitive data, or disrupting operations.
Likely Case
Attackers compromise user accounts with weak passwords, leading to unauthorized access to user data and potential lateral movement within the network.
If Mitigated
With proper rate limiting and account lockout policies, attackers cannot guess credentials within reasonable timeframes, reducing risk to acceptable levels.
🎯 Exploit Status
Brute-force attacks are well-understood and easily automated; no special tools required beyond standard password guessing scripts.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in provided references; consult vendor advisory
Vendor Advisory: https://www.sick.com/.well-known/csaf/white/2025/sca-2025-0010.json
Restart Required: No
Instructions:
1. Check vendor advisory for affected products. 2. Apply vendor-provided patches or updates. 3. Verify authentication controls are properly implemented.
🔧 Temporary Workarounds
Implement Rate Limiting
allConfigure web server or application to limit authentication attempts per IP/user
# Example for nginx: limit_req_zone $binary_remote_addr zone=auth:10m rate=5r/m;
# Then apply to auth endpoints
Enable Account Lockout
allConfigure temporary account lockout after failed attempts
# Application-specific configuration required
🧯 If You Can't Patch
- Implement network-level controls like WAF rules to block brute-force patterns
- Enforce strong password policies and multi-factor authentication
🔍 How to Verify
Check if Vulnerable:
Attempt multiple failed logins from same IP/user within short timeframe; if not blocked or throttled, system is vulnerable.Check Version:
Application-specific; consult vendor documentationVerify Fix Applied:
After applying controls, attempt brute-force attack; verify requests are blocked/throttled after configured limit.📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts from same source IP
- Rapid sequence of login failures for same username
Network Indicators:
- High volume of POST requests to login endpoints
- Pattern of failed HTTP 401 responses
SIEM Query:
sourceIP=* AND (eventType="authentication_failure") | stats count by sourceIP, username | where count > 10🔗 References
