What is CVE-2020-37020?

SonarQube version 8.3.1 contains an unquoted service path vulnerability, which poses a significant risk for local attackers. By exploiting this flaw, malicious users can manipulate the service executable path to replace the legitimate 'wrapper.exe' with a malicious executable. This can lead to code execution with SYSTEM-level privileges, especially upon service restart, allowing attackers to gain extensive control over the affected system. Organizations using SonarQube need to take immediate measures to mitigate this risk to safeguard their infrastructure.
