What is CVE-2021-42954?

The Zoho Remote Access Plus Server has a vulnerability stemming from improper access control mechanisms. Specifically, its Windows Desktop Binary allows unauthorized users to gain excessive permissions due to misconfigured access control lists (ACLs) in the installation directory. This flaw can enable non-admin and guest users full control of system files, providing a pathway for privilege escalation. Attackers may exploit this vulnerability to reset passwords without authorization, access sensitive data, view plaintext credentials, manipulate configuration files, and even alter registry values. This weakness highlights the importance of stringent file permission settings to safeguard user data and prevent unauthorized access.
