CVE-2021-30463 (GCVE-0-2021-30463)

Vulnerability from cvelistv5 – Published: 2021-04-08 13:54 – Updated: 2024-08-03 22:32

Summary

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.

Severity

No CVSS data available.
