Kerentanan Improper Link Resolution Before File Access ('Link Following') pada mariadb. Skor CVSS 3.1 7.8 (High) menurut NVD.

Deskripsi (NVD)

mysql_install_db in MariaDB 10.4.7 through 10.4.11 allows privilege escalation from the mysql user account to root because chown and chmod are performed unsafely, as demonstrated by a symlink attack on a chmod 04755 of auth_pam_tool_dir/auth_pam_tool. NOTE: this does not affect the Oracle MySQL product, which implements mysql_install_db differently.
