CVE-2021-30463

Public Exploit

Description

VestaCP through 0.9.8-24 allows attackers to gain privileges by creating symlinks to files for which they lack permissions. After reading the RKEY value from user.conf under the /usr/local/vesta/data/users/admin directory, the admin password can be changed via a /reset/?action=confirm&user=admin&code= URI. This occurs because chmod is used unsafely.
