7.8 · HIGHOverview
CVE-2021-30463 is a high-severity vulnerability affecting vestacp control_panel. It was published on April 8, 2021 and has a CVSS 3.1 base score of 7.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical 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.
Remediation
Check the references section for vendor advisories and patches from vestacp. Update control_panel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
