CVE-2021-35064 is a local privilege escalation vulnerability in KramerAV VIAWare affecting all tested versions. The issue is caused by an unsafe sudo configuration that permits execution of multiple dangerous commands with elevated privileges. Reported examples include unzip, systemctl, and dpkg. Because these programs can be abused to invoke privileged file writes, package operations, service manipulation, or command execution pathways, a local user with access to the affected system may be able to escalate privileges to root through the overly permissive sudoers policy.

This repository provides an operational exploit for CVE-2021-35064, targeting VIA Collaboration Hub devices. The main exploit script (CVE-2021-35064.py) is written in Python and automates the process of exploiting a file upload vulnerability in the device's web interface. The exploit works by sending a specially crafted POST request to the /ajaxPages/writeBrowseFilePathAjax.php endpoint, which writes a PHP script to the web server's document root. This PHP script, when executed, downloads and saves a more advanced PHP web shell (pwny.php) from a remote GitHub repository. The exploit then verifies the presence of the shell and provides instructions for privilege escalation using the RPM Lua interface. The repository also includes search dorks for Shodan and Zoomeye to help identify vulnerable devices on the internet. The structure is straightforward: one main exploit script, a README with usage instructions and search dorks, and two text files containing the dorks. The exploit is operational, providing a working web shell and clear post-exploitation steps.
