CVE-2025-57700
📋 TL;DR
CVE-2025-57700 is a stored cross-site scripting (XSS) vulnerability in DIAEnergie energy management software that allows attackers to inject malicious scripts into web pages. When users view compromised pages, the scripts execute in their browsers, potentially stealing session cookies or performing unauthorized actions. Organizations using vulnerable DIAEnergie installations are affected.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, hijack user sessions, deface the application, or redirect users to malicious sites, potentially leading to complete system compromise.
Likely Case
Attackers steal session cookies to impersonate users, perform unauthorized actions within the application, or deploy credential harvesting pages.
If Mitigated
With proper input validation and output encoding, malicious scripts are neutralized before reaching users, preventing exploitation.
🎯 Exploit Status
Exploitation requires ability to inject malicious scripts into stored content that other users will view; typically requires some level of access to the application.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Consult Delta advisory for specific patched versions
Vendor Advisory: https://filecenter.deltaww.com/news/download/doc/Delta-PCSA-2025-00012_DIAEnergie%20Cross-Site%20Scripting%20Vulnerabilities.pdf
Restart Required: No
Instructions:
1. Download the security patch from Delta's official website. 2. Apply the patch according to vendor instructions. 3. Verify the fix by testing XSS payloads in previously vulnerable fields.
🔧 Temporary Workarounds
Implement Web Application Firewall (WAF)
allDeploy a WAF with XSS protection rules to filter malicious script payloads before they reach the application.
Content Security Policy (CSP)
allImplement strict CSP headers to restrict script execution sources and prevent inline script execution.
Content-Security-Policy: default-src 'self'; script-src 'self'
🧯 If You Can't Patch
- Implement network segmentation to isolate DIAEnergie systems from untrusted networks
- Disable unnecessary user input fields or implement client-side input validation as temporary measure
🔍 How to Verify
Check if Vulnerable:
Test input fields for XSS by injecting basic script payloads like <script>alert('XSS')</script> and checking if they execute when viewed.Check Version:
Check DIAEnergie version through web interface or consult application documentation for version identification.Verify Fix Applied:
After patching, retest XSS payloads in all user input fields to ensure they are properly sanitized and do not execute.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests containing script tags or JavaScript code in parameters
- Multiple failed login attempts followed by successful login from same IP
Network Indicators:
- HTTP requests with suspicious parameters containing script elements
- Outbound connections to unknown domains from user browsers
SIEM Query:
source="web_logs" AND (uri="*<script>*" OR param="*javascript:*" OR param="*onerror=*" OR param="*onload=*")
