CVE-2025-55057
📋 TL;DR
This CVE describes a Cross-Site Request Forgery (CSRF) vulnerability that allows attackers to trick authenticated users into performing unintended actions on web applications. It affects systems with web interfaces that lack proper CSRF protections. Users who access vulnerable applications while authenticated are at risk.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could perform administrative actions like changing configurations, creating new accounts, or modifying data on behalf of authenticated users.
Likely Case
Attackers trick users into changing their own settings or performing limited actions within their privilege scope.
If Mitigated
Proper CSRF tokens and same-origin policies prevent exploitation, limiting impact to theoretical.
🎯 Exploit Status
CSRF attacks typically require user interaction (visiting malicious page while authenticated) but are technically simple to implement.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified
Vendor Advisory: https://www.gov.il/en/departments/dynamiccollectors/cve_advisories_listing?skip=0
Restart Required: No
Instructions:
1. Check the provided advisory link for specific vendor patches. 2. Apply vendor-recommended updates if available. 3. For custom applications, implement CSRF tokens and validate same-origin headers.
🔧 Temporary Workarounds
Implement CSRF Tokens
allAdd unique, unpredictable tokens to all state-changing forms and validate them server-side
SameSite Cookie Attribute
allSet SameSite=Strict or Lax on session cookies to prevent cross-site requests
Set-Cookie: session=abc123; SameSite=Strict; Secure; HttpOnly
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to detect and block CSRF patterns
- Require re-authentication for sensitive operations and use multi-step confirmation for state changes
🔍 How to Verify
Check if Vulnerable:
Test web forms for missing CSRF tokens using browser developer tools or automated scanners like OWASP ZAPCheck Version:
Check application version through admin interface or version files specific to the softwareVerify Fix Applied:
Verify that all POST/PUT/DELETE requests include validated CSRF tokens and check cookie SameSite attributes📡 Detection & Monitoring
Log Indicators:
- Multiple failed state-changing requests from same user with missing/rejected tokens
- Unusual parameter patterns in form submissions
Network Indicators:
- State-changing requests (POST/PUT/DELETE) lacking Referer headers or CSRF tokens
- Requests originating from unexpected domains
SIEM Query:
web_requests method=POST AND (NOT csrf_token=*) OR (referer NOT CONTAINS "yourdomain.com")
