ISS X-Force Database: mysql-myisam-symlink-security-bypass(45649): MySQL MyISAM symlink security bypass

MySQL MyISAM symlink security bypass

mysql-myisam-symlink-security-bypass (45649)

Medium Risk

Description:

MySQL could allow a local attacker to bypass security restrictions. By calling CREATE TABLE on a MyISAM table with modified DATA DIRECTORY or INDEX DIRECTORY arguments that are originally associated with pathnames without symlinks, and that can point to tables created at a future time at which a pathname is modified to contain a symlink to a subdirectory of the MySQL home data directory, an attacker could bypass certain privilege checks.

CVE-2008-4098: MySQL before 5.0.67 allows local users to bypass certain privilege checks by calling CREATE TABLE on a MyISAM table with modified (1) DATA DIRECTORY or (2) INDEX DIRECTORY arguments that are originally associated with pathnames without symlinks, and that can point to tables created at a future time at which a pathname is modified to contain a symlink to a subdirectory of the MySQL home data directory. NOTE: this vulnerability exists because of an incomplete fix for CVE-2008-4097.
