Studio 42 elFinder 2.1.64 is vulnerable to Incorrect Access Control. Copying files with an unauthorized extension between server directories allows an arbitrary attacker to expose secrets, perform RCE, etc.

Studio-42 eLfinder 2.1.62 is vulnerable to Remote Code Execution (RCE) as there is no restriction for uploading files with the .php8 extension.

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

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.

The package studio-42/elfinder before 2.1.58 are vulnerable to Remote Code Execution (RCE) via execution of PHP code in a .phar file. NOTE: This only applies if the server parses .phar files as PHP.

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.

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

Studio 42 elFinder before 2.1.36 has a directory traversal vulnerability in elFinder.class.php with the zipdl() function that can allow a remote attacker to download files accessible by the web server process and delete files owned by the account running the web server process.

Studio 42 elFinder before 2.1.37 has a directory traversal vulnerability in elFinder.class.php with the zipdl() function that can allow a remote attacker to download files accessible by the web server process and delete files owned by the account running the web server process. NOTE: this issue exists because of an incomplete fix for CVE-2018-9109.

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.

elFinder is an open-source file manager for web, written in JavaScript using jQuery UI. Prior to 2.1.67, elFinder contains a command injection vulnerability in the resize command. The bg (background color) parameter is accepted from user input and passed through image resize/rotate processing. In configurations that use the ImageMagick CLI backend, this value is incorporated into shell command strings without sufficient escaping. An attacker able to invoke the resize command with a crafted bg value may achieve arbitrary command execution as the web server process user. This vulnerability is fixed in 2.1.67.

A Server Side Request Forgery (SSRF) vulnerability in elFinder before 2.1.46 could allow a malicious user to access the content of internal network resources. This occurs in getremotecontents() in php/elFinder.class.php.

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

Studio-42 eLfinder 2.1.62 contains a filename restriction bypass leading to a persistent Cross-site Scripting (XSS) vulnerability.

php/elFinder.class.php in elFinder before 2.1.45 leaks information if PHP's curl extension is enabled and safemode or openbasedir is not set.

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