CVE-2023-50165
📋 TL;DR
Pega Platform versions 8.2.1 through 23.1.0 contain a server-side request forgery (SSRF) vulnerability in the PDF generation functionality. This allows authenticated attackers to read arbitrary files from the server filesystem. Organizations using affected Pega Platform versions are at risk.
💻 Affected Systems
- Pega Platform
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of sensitive server files including configuration files, credentials, and application data leading to full system compromise.
Likely Case
Unauthorized access to sensitive files containing business data, configuration secrets, or personally identifiable information.
If Mitigated
Limited exposure of non-critical files if proper network segmentation and file permissions are enforced.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once authenticated.
