elFinder: ZIP extraction bypasses uploadDeny MIME filter allowing PHP file upload (RCE)

elFinder is an open-source file manager for web, written in JavaScript using jQuery UI. Prior to 2.1.70, checkExtractItems() in php/elFinderVolumeDriver.class.php calls mimetypeInternalDetect() without passing the result through mimeTypeNormalize(). Because the .phtml, .phar, .php5, and .php3 extensions are absent from mime.types, the staticMimeMap entries that map them to text/x-php are not applied, and allowPutMime() permits extraction even when uploadDeny blocks text/x-php. An attacker with ZIP upload permission can extract PHP-executable files into a web-accessible files/ directory and achieve remote code execution when the server execute

elFinder: CSRF in netmount allows forced FTP mounts and server-side FTP connections

elFinder is an open-source file manager for web, written in JavaScript using jQuery UI. Prior to 2.1.70, the netmount command is omitted from elFinderConnector::$csrfProtectedCmds in php/elFinderConnector.class.php, so validateCsrfToken() is not called for this state-changing operation. In the shipped php/connector.minimal.php-dist configuration, FTP network mounts are enabled by default, and attacker-controlled protocol, host, path, port, user, pass, alias, and options arguments flow through elFinder::netmount() in php/elFinder.class.php to php/elFinderVolumeFTP.class.php. A cross-site request can therefore persist an attacker-chosen FTP mou

elFinder: SSRF protection bypass via DNS rebinding in the `fsock_get_contents()` fallback

elFinder is an open-source file manager for web, written in JavaScript using jQuery UI. Prior to 2.1.70, elFinder URL uploads in php/elFinder.class.php can bypass server-side request forgery protections when PHP cURL is unavailable because validate_address() validates $info['ip'], but get_remote_contents() selects fsock_get_contents(), which connects to $arr['host'] and performs a second DNS resolution. An attacker able to submit a URL upload can use DNS rebinding to have the first resolution return a public address and the connection resolution return a loopback or private address, causing the internal HTTP response body to be stored as an u

elFinder: SQL Injection MySQL Volume Driver (elFinderVolumeMySQL)

elFinder is an open-source file manager for web, written in JavaScript using jQuery UI. Prior to 2.1.68, 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. This vulnerability is fixed in 2.1.68.

elFinder: Command injection in resize background color parameter when using ImageMagick CLI

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.

CVE-2024-38909

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.

CVE-2023-35840

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

• Update to 2.1.62

CVE-2022-27115

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

• Update to 2.1.61

CVE-2021-43421

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.

• Update to 2.1.60

CVE-2022-26960

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.

• Update to 2.1.61

CVE-2021-45919

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

Multiple vulnerabilities leading to RCE

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.

• Update to 2.1.59

Remote Code Execution (RCE)

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.

• Update to 2.1.58

CVE-2019-9194

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

• Update to 2.1.48

CVE-2019-6257

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 get_remote_contents() in php/elFinder.class.php.

• Update to 2.1.49

CVE-2019-5884

CVE-2018-9110

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.

CVE-2018-9109

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.
