Originally, as explained in an advisory from Wordfence, its only functionality was to upload photos, however a recent change saw the plugin augumented with new features including user login and registration.
Marc-Alexandre Montpas, from our research team, found a serious security vulnerability in the MailPoet WordPress plugin. This bug allows an attacker to upload any file remotely to the vulnerable website (i.e., no authentication is required).
[TRENDING] Remote Upload – WordPress Plugin
The problem I think is multi-layered. Many themes use this plugin and there is no real way of communicating issues of this nature. That is something that I think wordpress should look at including. A method that allows a plugin author to submit a warning, which triggers on their website and emails the webmaster.We were not emailed about this issue as it was part of a theme that was purchased from ThemeForrest.
Thank you for bringing this to our attention. I have disable this plugin for now. Can you please tell us what and where to look to be able to find if anyone inserted, or uploaded, something not wanted on our server. Is it all contained within their folder or could the person upload into other areas too?
The same for me, base64 encoded code in all of the PHP files on my server, apparently, the code is sended from remote to my site using the admin-post.php and wp-content/uploads/wysija/themes/mailp/index.php.
Firstly, sorry if I seem cocky, but after spending so much time and money to secure our server against vulnerabilities and other attacks, I am pleased to report that our customers are safe. We had one customer who used this plugin and the vulnerability was exploited and a file was uploaded. However, due to our other security measures, they were unable to use the vulnerability to do anything. The upload was checked and never went live. A full scan was completed (which automatically completes each night) to look for base64 and any other suspect items. We downloaded all files and manually checked them ourselves to ensure they were clean. We then notified the effected customer of the issue and informed them that they were fully protected and the exploits all failed. Naturally, we then changed all passwords just to be doubly sure.
There is an easily exploitable remote code execution vulnerability in a popular WordPress plugin that helps manage file downloads and researchers say the bug could be used by even a low-level attacker to run arbitrary code on a vulnerable site.
Today we will be diving into three different methods on how to install WordPress plugins on your website. This includes searching from within your WordPress dashboard, manually uploading a plugin via SFTP, and installing a plugin via WP-CLI. In these following examples, we are going to use the popular free Yoast SEO plugin, which is currently installed on more than 1 million WordPress sites.
Then via your FTP client, upload the plugin to your /public/wp-content/plugins directory. Note: You will need to grab the plugin folder within the named plugin folder. For example, under the wordpress-seo.3.5 folder there is another folder called wordpress seo. That is the folder you want to move over.
Vulnerabilities in WordPress Popular Posts plugin weaponized and productized. Exploitation of these vulnerabilities could allow an attacker to perform arbitrary file uploads and remote code execution.
Visual Studio Code is a popular Integrated Developer Environment (IDE) for developers. Its large selection of plugins, minimal design, and cross-platform support make it a great choice for developers of all levels. This tutorial focuses on using the Remote-SSH plugin to enable remote software development. With this plugin you can edit files on your local workstation, but run development tasks such as program execution, unit tests, or static analysis on a remote server.
Note: If you have any development extensions installed in Visual Studio Code, like the Python extension, you will have to reinstall these extensions on your server through the Extension Marketplace. If you have previously installed these plugins in Visual Studio Code, when you search for them again, the Marketplace will say Install on SSH: hostname. Always pay attention to what devlopment context you are in, because this is where Visual Studio Code will install your plugins and create your files. If you try to run your code without these plugins installed, error dialog boxes will appear in the bottom right-hand corner of the screen prompting you to install them on your remote server. After you have installed these they will likely require you to reload Visual Studio Code. When you relaunch it, it will continue working on the remote server without you having to manually reconnect.
Another issue you could potentially face is if a new plugin you recently installed is causing a conflict with UpdraftPlus. Deactivate any new plugins and try backing up again. Common causes of conflicts are plugins loading their own versions of JavaScript libraries or cloud storage APIs on the UpdraftPlus page. These can prevent UpdraftPlus from starting a backup or uploading the backup files to remote storage.
Aside from the above issues users of UpdraftPlus may encounter, such as not having the remote storage location properly setup, the most common technical reasons for a backup failing to complete is that you are trying to backup a file that is too large to upload or the file on the server is too large to process.
In the situation where the file is too large to upload, this can be caused by some plugins creating databases or files that are many hundreds of MB large. These large files can cause UpdraftPlus to time out and not complete the backup. You should always aim to reduce the backup archive split size to 100MG or lower if possible.
The plugin enables users to customize any type of products ranging from clothing articles to accessories and household items by uploading their own images or PDF files. It is used by a variety of platforms, including WordPress, WooCommerce and Shopify.
iThemes Sync will attempt to login using the details provided, and if successful, will automatically install the iThemes Sync WordPress Plugin so it can communicate with your WordPress website to remotely update its themes and plugins.
The first critical vulnerability, which has been issued a CVSS severity score of 9, was disclosed by cybersecurity researchers on December 22, 2020. Described as a PHP Object injection and found in the run_action() function of the software, this flaw made it possible for hackers to use the compromised plugin to upload a file and proceed to a Remote Code Execution (RCE).
The Total Upkeep plugin offers several options for storing WordPress Backups remotely. You have the option of storing them on the web server, your local computer, a remote FTP server, or even Google Drive or Amazon S3 if you are a Premium Connect Key user! The following guide will explain how to configure your Backup Plugin to store your WordPress backups remotely.
In December 2020, Unit 42 researchers observed attempts to exploit CVE-2020-25213, which is a file upload vulnerability in the WordPress File Manager plugin. Successful exploitation of this vulnerability allows an attacker to upload an arbitrary file with arbitrary names and extensions, leading to Remote Code Execution (RCE) on the targeted web server.
The vulnerability stems from the fact that the WordPress File Manager plugin renamed the file extension on the elFinder library's connector.minimal.php.dist file to .php so it could be executed directly. Since this file has no access restrictions, it can be executed by anyone browsing the web server. The file contains mechanisms to upload files to the web server without any authentication. Because of this flaw, allowing anyone to upload files, malicious actors started attacking it and uploading webshells, which can be used for further activities such as installing malware or cryptominers.
The reason for trying to download the image instead of looking for it locally is for the case that some plugin generates the image on the fly when the URL is visited. Take note here that no sanitization whatsoever is performed here. WordPress will simply concatenate the upload directory and the URL with the $src_file user input. Once WordPress has successfully loaded a valid image via wp_get_image_editor(), it will crop the image.
I am looking to overwrite the existing upload functionality to save the file on a remote storage service. The remote storage has an HTTP interface that allow me to post file and return an addressable URL back. The reason for doing this is that the remote storage service has large amount of space and is automatically replicated for high-availability.
