If CVE-2020-11107 is a vulnerability of the past, is a critical, high-risk (CVSS 9.8) vulnerability that is still very relevant today. It represents a new generation of XAMPP exploits that are even more severe because they do not require local access; they can be triggered remotely.
Lateral Movement: Using the compromised server as a foothold to attack other systems within the same network. Mitigation and Prevention
: When an unsuspecting administrator needs to check a log file to debug a server issue and clicks the "Logs" button in the XAMPP Control Panel, the XAMPP application launches what it thinks is the text editor. Instead, it launches the attacker's batch file or executable with the administrator's elevated privileges.

By staying informed and taking proactive measures, you can safeguard your XAMPP installation and prevent similar exploits from affecting your system.
XAMPP versions prior to 7.4.4 (which extended directly into unpatched dependencies packaged within version 7.4.6 distributions) suffer from a flaw where unprivileged users can modify the global configuration file ( xampp-control.ini ). This allows low-privilege actors to hijack system logs or administrative interactions to run malicious files with elevated privileges.
: The user identifies that they can modify xampp-control.ini . XAMPP 7
The most effective defense against these exploits is to completely replace the outdated stack.
Tell me which safe option you prefer.
: When an administrative user opens a log file through the panel, the system executes the attacker’s malicious payload instead of Notepad, inheriting high-level system privileges. 2. Underlying PHP 7.4 Runtime Vulnerabilities
