CVE-2025-46390
📋 TL;DR
CVE-2025-46390 is an observable response discrepancy vulnerability (CWE-204) that allows attackers to infer sensitive information by analyzing differences in system responses. This affects systems that leak information through timing differences, error messages, or other observable variations. Organizations using vulnerable software versions are potentially affected.
💻 Affected Systems
- Unknown - specific products not identified in provided reference
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).
🔒 Custom verification scripts are available for registered users. Sign up free to download automated test scripts.
- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Attackers could enumerate valid users, infer internal system state, bypass authentication, or extract sensitive data through side-channel analysis.
Likely Case
Information disclosure allowing user enumeration, system fingerprinting, or partial data leakage through observable differences in responses.
If Mitigated
Limited information leakage with proper input validation, uniform error responses, and rate limiting in place.
🎯 Exploit Status
CWE-204 vulnerabilities are often easy to exploit with basic tools like curl or custom scripts to analyze response differences.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.gov.il/en/departments/dynamiccollectors/cve_advisories_listing?skip=0
Restart Required: No
Instructions:
1. Monitor vendor advisory for patch availability
2. Apply vendor-recommended patches when released
3. Test patches in non-production environment first
🔧 Temporary Workarounds
Implement uniform error responses
allEnsure all error conditions return identical response timing, format, and content
Add response timing normalization
allImplement artificial delays to make all response times uniform
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to normalize responses
- Add rate limiting and monitoring for enumeration attempts
🔍 How to Verify
Check if Vulnerable:
Test with different inputs and analyze response timing, content, and error messages for observable differencesCheck Version:
Check software version against vendor advisory when availableVerify Fix Applied:
Verify that all responses (valid and invalid) have identical timing, format, and content📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts with different response times
- Patterns of sequential user enumeration attempts
Network Indicators:
- Unusual patterns of similar requests with slight variations
- High volume of error responses
