PHPStudy development environment versions 2016 through 2018 contain an embedded backdoor that executes arbitrary PHP code from HTTP request headers. The backdoor listens for base64-encoded payloads in the Accept-Charset header, decodes and executes them without any authentication, providing complete remote code execution on any server running the compromised PHPStudy.
An unauthenticated remote code execution vulnerability exists in Remote for Mac, a macOS remote control utility developed by Aexol Studio, in versions up to and including 2025.7. When the application is configured with authentication disabled (i.e., the "Allow unknown devices" option is enabled), the /api/executeScript endpoint is exposed without access control. This allows unauthenticated remote attackers to inject arbitrary AppleScript payloads via the X-Script HTTP header, resulting in code execution using do shell script. Successful exploitation grants attackers the ability to run arbitrary commands on the macOS host with the privileges of the Remote for Mac background process.
A command injection vulnerability exists in IGEL OS versions prior to 11.04.270 within the Secure Terminal and Secure Shadow services. The flaw arises due to improper input sanitization in the handling of specially crafted PROXYCMD commands on TCP ports 30022 and 5900. An unauthenticated attacker with network access to a vulnerable device can inject arbitrary commands, leading to remote code execution with elevated privileges. NOTE: IGEL OS v10.x has reached end-of-life (EOL) status.
Arbitrary file upload vulnerability in AiBud WP plugin for WordPress versions up to 1.8.5 allows authenticated attackers with high privileges to upload web shells, leading to remote code execution on the web server. Proof-of-concept exploit code is publicly available, but no active exploitation is confirmed (not in CISA KEV) and EPSS indicates low exploitation probability.
