Verified Advisory
Zip slip remote code execution in efw4.X (CVE-2026-44257)
efw.file.FileManager.unZip extracts zip entries without validating canonical paths, allowing directory traversal via crafted entry names such as `../../../pwned.jsp`. Combined with the framework's multipart /uploadServlet, an unauthenticated remote attacker can write a JSP webshell to the servlet context root and execute arbitrary commands as the Tomcat process user.
Affected versions:
- <= 4.08.009
We recommend updating to: 4.08.010.
