CVE-2023-25913
📋 TL;DR
CVE-2023-25913 is an authentication flaw that allows attackers to generate web reports containing sensitive information like internal IP addresses, usernames, and store names. This affects systems running vulnerable versions of the software where authentication mechanisms are improperly implemented. Organizations using the affected software without proper access controls are at risk.
💻 Affected Systems
- Specific software not named in references; appears to be a web reporting application
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete exposure of internal network information, usernames, and sensitive business data leading to further attacks like credential theft, lateral movement, or data exfiltration.
Likely Case
Disclosure of internal IP addresses and usernames enabling reconnaissance for follow-up attacks.
If Mitigated
Limited to no impact if proper authentication and access controls are enforced.
🎯 Exploit Status
Exploitation requires no authentication and involves triggering web report generation to leak sensitive data.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified
Vendor Advisory: https://csirt.divd.nl/CVE-2023-25913
Restart Required: No
Instructions:
1. Monitor vendor advisory for patch release. 2. Apply patch when available. 3. Verify authentication mechanisms are properly implemented.
🔧 Temporary Workarounds
Disable web report generation
allTemporarily disable the vulnerable web report generation feature if not essential.
Feature-specific disable command not available; check software documentation
Implement strict access controls
allRestrict access to report generation functionality to authenticated users only.
Configure access control lists or firewall rules to limit access
🧯 If You Can't Patch
- Isolate affected systems from internet and restrict internal network access.
- Implement network segmentation and monitor for unauthorized report generation attempts.
🔍 How to Verify
Check if Vulnerable:
Test if unauthenticated users can generate web reports that disclose sensitive information.
Check Version:
Check software version via administrative interface or documentation.
Verify Fix Applied:
Verify that authentication is required for web report generation and no sensitive data is leaked.
📡 Detection & Monitoring
Log Indicators:
- Unauthenticated requests to report generation endpoints
- Unusual report generation activity
Network Indicators:
- HTTP requests to report endpoints without authentication headers
SIEM Query:
source="web_logs" AND (uri="/report/generate" OR uri CONTAINS "report") AND auth_status="failed"
