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.

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

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.

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.

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.

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.

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 allows stored XSS

elFinder before 2.1.59 contains multiple vulnerabilities leading to RCE

elFinder unsafe upload filtering leading to remote code execution

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

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.

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.
