Exploitation Summary
EIP tracks 2 public exploits for CVE-2020-15261. PoCs published by Víctor García.
AI-analyzed exploit summary This is a writeup describing an unquoted service path vulnerability in Veyon 4.4.1. The vulnerability could allow local privilege escalation if an attacker can place an executable in a path that is executed due to improper quoting.
Description
On Windows the Veyon Service before version 4.4.2 contains an unquoted service path vulnerability, allowing locally authenticated users with administrative privileges to run malicious executables with LocalSystem privileges. Since Veyon users (both students and teachers) usually don't have administrative privileges, this vulnerability is only dangerous in anyway unsafe setups. The problem has been fixed in version 4.4.2. As a workaround, the exploitation of the vulnerability can be prevented by revoking administrative privileges from all potentially untrustworthy users.
