Overview
In this blog post, we delve into a critical security vulnerability, identified as CVE-2025-11020, that affects MarkAny SafePC Enterprise. This serious flaw, with a CVSS severity score of 8.8, could allow an attacker to obtain sensitive server information and possibly exploit an unrestricted file upload vulnerability. It’s crucial to understand this vulnerability because it affects an extensive range of MarkAny SafePC Enterprise versions on both Windows and Linux platforms, leading to potential system compromise or data leakage.

How the Exploit Works
The vulnerability lies in the Path Traversal and the unrestricted file upload feature of the MarkAny SafePC Enterprise software. An attacker could exploit this flaw by sending a specifically crafted request to the server. This request would manipulate the file path to navigate out of the intended directory, typically leading to unauthorized access to files.
The attacker can then use this unauthorized access to conduct an SQL Injection attack. Through this method, they can manipulate the software’s SQL queries, potentially gaining unauthorized access to sensitive data within the database.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. In this HTTP request, the attacker is using a “..” sequence to navigate the directory structure and access unauthorized files (Path Traversal). They are then injecting a malicious SQL statement (SQL Injection) through the unrestricted file upload feature:
POST /upload_file/ HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data
--boundary
Content-Disposition: form-data; name="file"; filename="../etc/passwd"
Content-Type: text/plain
'; DROP TABLE users; --
--boundary--Mitigation
The most effective mitigation for this vulnerability is to apply the vendor-provided patch. If that’s not immediately possible, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation measure. It’s also recommended to restrict file uploads to only trusted and authenticated users and to validate all inputs rigorously to prevent SQL Injection.
