What is CVE-2021-30463?

VestaCP versions prior to 0.9.8-24 are susceptible to a local privilege escalation vulnerability. Attackers can exploit this weakness by creating symbolic links to files, allowing them to manipulate user permissions. Specifically, through an improperly secured access process, an attacker can read sensitive configuration values, such as the RKEY from user.conf located in the /usr/local/vesta/data/users/admin directory. This enables them to reset the admin password via a targeted URI request. The use of the chmod command inappropriately creates a security loophole that can be exploited for unauthorized access.
