**Name of the Vulnerable Software and Affected Versions** OpenPLC version 3 **Description** The software contains an authenticated remote code execution issue. An attacker with valid credentials can inject malicious code through the hardware configuration interface. This allows for the upload of a custom hardware layer containing reverse shell code, which establishes a network connection to a specified IP and port, enabling remote command execution. The vulnerable interface is the hardware configuration interface. Attackers can upload a custom hardware layer with embedded reverse shell code. The reverse shell code establishes a network connection to a specified IP and port, enabling remote command execution. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Shopp WordPress plugin versions 1.4 and earlier **Description** The issue concerns the lack of security measures in the `shopp upload file` AJAX action, allowing both unauthenticated and authenticated users to upload malicious files, such as PHP files, without restriction. This can lead to remote code execution (RCE) as unauthenticated users can upload arbitrary files. **Recommendations** For Shopp WordPress plugin versions 1.4 and earlier, as a temporary workaround, consider disabling the `shopp upload file` AJAX action until a patch is available. Restrict access to file upload functionality to minimize the risk of exploitation. Avoid using the file upload feature in the affected plugin until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** WordPress Simple Ecommerce Shopping Cart Plugin- Sell products through Paypal plugin versions 2.2.5 and earlier **Description** The issue allows any file, such as PHP, to be uploaded by an administrator due to a lack of checks for uploaded Downloadable Digital product files. Additionally, the absence of CSRF protection enables attackers to make a logged-in admin upload a malicious PHP file, leading to remote code execution (RCE). **Recommendations** For WordPress Simple Ecommerce Shopping Cart Plugin- Sell products through Paypal plugin versions 2.2.5 and earlier, update to a version later than 2.2.5 to resolve the issue. As a temporary workaround, consider restricting file uploads to only necessary file types and implementing CSRF protection to minimize the risk of exploitation.

This can lead to malicious script execution when the page is accessed. **Recommendations** For OpenPLC runtime versions V3 through 2016-03-14, consider restricting access to the "Add New Device" page until a fix is available. As a temporary workaround, avoid using the `Device Name` field in the web server's Add New Device page to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
