Description
PDFPatcher thru 1.1.3.4663 executable's XML bookmark import functionality does not restrict XML external entity (XXE) references. The application uses .NET's XmlDocument class without disabling external entity resolution, enabling attackers to: Read arbitrary files from the victim's filesystem, exfiltrate sensitive data via out-of-band (OOB) HTTP requests, perform SSRF attacks against internal network resources, or cause a denial of service via entity expansion attacks.

Executive Summary

This vulnerability exists in PDFPatcher's XML bookmark import functionality, which does not restrict XML external entity (XXE) references. Because the application uses .NET's XmlDocument class without disabling external entity resolution, attackers can exploit this to read arbitrary files on the victim's filesystem, exfiltrate sensitive data via out-of-band HTTP requests, perform server-side request forgery (SSRF) attacks against internal network resources, or cause denial of service through entity expansion attacks.

Impact Analysis

The vulnerability can lead to unauthorized access to sensitive files on your system, data leakage through exfiltration of information, potential attacks on internal network resources via SSRF, and denial of service conditions caused by entity expansion attacks, all of which can compromise system security and availability.
