Advisories for Composer/Studio-42/Elfinder package

elFinder provides uploadDeny and uploadAllow options in its connector configuration to restrict which MIME types may be uploaded. When uploadDeny includes text/x-php, direct upload of .php, .phtml, and .phar files is correctly blocked. However, the extract command (ZIP decompression) internally calls checkExtractItems(), which invokes mimetypeInternalDetect() directly without passing the result through mimeTypeNormalize(). Because phtml, phar, and similar PHP-executable extensions are absent from mime.types, they are not resolved to text/x-php at …

The PHP connector's CSRF gate protects many mutating commands, but it does not protect the netmount connector command. In the shipped minimal connector setup, FTP network mounting is enabled by default, so a cross-site request can force an elFinder instance to mount an attacker-chosen FTP endpoint in the victim's session and cause the server to initiate an outbound FTP connection without the X-elFinder-CSRF token that other state-changing commands require. This …

elFinder 2.1.69 is vulnerable to a Server-Side Request Forgery (SSRF) protection bypass when PHP cURL is unavailable and URL uploads use the fsock_get_contents() fallback. An attacker who can submit a URL for server-side upload can use an attacker-controlled DNS hostname that initially resolves to an allowed public IP address and subsequently resolves to a loopback or private IP address. The URL validation checks the first resolved IP, but fsock_get_contents() opens …

An authenticated SQL injection vulnerability in the elFinder MySQL volume driver (elFinderVolumeMySQL) allows any logged-in user, including users with read-only access to the affected volume, to inject SQL through a crafted target file hash. Successful exploitation can lead to unauthorized data disclosure and denial of service. This vulnerability only affects installations configured to use the MySQL volume driver. Installations using the default LocalFileSystem driver are not affected.

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 …

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 elFinder allows XSS via an SVG document.

elFinder is an open-source file manager for web, written in JavaScript using jQuery UI. Several vulnerabilities affect elFinder 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 As a workaround, ensure the connector is not exposed without authentication.

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

elFinder has a command injection vulnerability in the PHP connector.

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

php/elFinder.class.php in elFinder leaks information if PHP's curl extension is enabled and safe_mode or open_basedir is not set.

Studio elFinder 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.
