elFinder is an open-source file manager for web, written in JavaScript using jQuery UI. Several vulnerabilities affect elFinder 2.1.58. These vulnerabilities can allow an attacker to execute arbitrary code and commands on the server hosting the elFinder PHP connector, even with minimal configuration. The issues were patched in version 2.1.59. As a workaround, ensure the connector is not exposed without authentication.

A File Upload vulnerability exists in Studio-42 elFinder 2.0.4 to 2.1.59 via connector.minimal.php, which allows a remote malicious user to upload arbitrary files and execute PHP code.

elFinder before 2.1.48 has a command injection vulnerability in the PHP connector.

_joinPath in elFinderVolumeLocalFileSystem.class.php in elFinder before 2.1.62 allows path traversal in the PHP LocalVolumeDriver connector.

In Studio-42 elFinder 2.1.60, there is a vulnerability that causes remote code execution through file name bypass for file upload.

connector.minimal.php in std42 elFinder through 2.1.60 is affected by path traversal. This allows unauthenticated remote attackers to read, write, and browse files outside the configured document root. This is due to improper handling of absolute file paths.

Studio 42 elFinder through 2.1.31 allows XSS via an SVG document.

This affects all versions of package elFinder.NetCore. The Path.Combine(...) method is used to create an absolute file path. Due to missing sanitation of the user input and a missing check of the generated path its possible to escape the Files directory via path traversal

This affects all versions of package elFinder.NetCore. The ExtractAsync function within the FileSystem is vulnerable to arbitrary extraction due to insufficient validation.

This affects the package elFinder.AspNet before 1.1.1. The user-controlled file name is not properly sanitized before it is used to create a file system path.
