A deserialization vulnerability exists in the H2O-3 REST API (POST /99/ImportSQLTable) that affects all versions up to 3.46.0.7. This vulnerability allows remote code execution (RCE) due to improper validation of JDBC connection parameters when using a Key-Value format. The vulnerability is present in the MySQL JDBC Driver version 8.0.19 and JDK version 8u112. The issue is resolved in version 3.46.0.8.

Buffer overflow in getsaltfrompassword from sqlacl.cc for MySQL 4.0.14 and earlier, and 3.23.x, allows attackers with ALTER TABLE privileges to execute arbitrary code via a long Password field.

Multiple format string vulnerabilities in the dispatchcommand function in libmysqld/sqlparse.cc in mysqld in MySQL 4.0.0 through 5.0.83 allow remote authenticated users to cause a denial of service (daemon crash) and possibly have unspecified other impact via format string specifiers in a database name in a (1) COMCREATEDB or (2) COMDROPDB request. NOTE: some of these details are obtained from third party information.

WriteFreely through 0.15.1, when MySQL is used, allows local users to discover credentials by reading config.ini.

The installation scripts in the Gentoo dev-db/mysql, dev-db/mariadb, dev-db/percona-server, dev-db/mysql-cluster, and dev-db/mariadb-galera packages before 2017-09-29 have chown calls for user-writable directory trees, which allows local users to gain privileges by leveraging access to the mysql account for creation of a link.

Stack-based buffer overflow in the websql CGI program in MySQL MaxDB 7.5.00 allows remote attackers to execute arbitrary code via a long password parameter.

MySQL 3.x before 3.23.59, 4.x before 4.0.19, 4.1.x before 4.1.2, and 5.x before 5.0.1, checks the CREATE/INSERT rights of the original table instead of the target table in an ALTER TABLE RENAME operation, which could allow attackers to conduct unauthorized activities.

Security Fix: Replication: It was possible when using statement-based replication to subvert the MySQL privilege system on a slave with a higher server release version number than that of the master by using version-specific comments in statements run on the master.

A more detailed explanation follows:

In MySQL, a version-specific comment is an SQL comment of the form /!nnnnn sql / where nnnnn represents a MySQL release version number and sql represents a string of SQL, or a portion of a string of SQL, that should be executed by the MySQL Server only if the server version is at least version n.nn. (For additional information and an example, see Section 8.6, “Comment Syntax”.)

In MySQL replication, the slave SQL thread executes with the SUPER privilege, regardless of the privileges with which statements are originally executed on the master. Specific to this issue, when using statement-based replication it was possible, when the slave was of a higher MySQL version than the master, to run statements that would have failed on the master due to insufficient privileges, except that these statements were wrapped in version-specific comments where the encoded version was greater than the MySQL server version of the master. However, if the MySQL release version of the slave was equal to or greater than the version encoded in the comment, the same statements could execute on this slave whose MySQL release version was less than the version number used in the comment.

Suppose that a master running MySQL 5.1.48 replicated to a slave running MySQL 4.1.49, and that a user user1 had privileges to run UPDATE statements on database db1 but no privileges at all on the mysql system database, so that the first of the following two statements succeeded, but the second statement failed, and thus the first statement was written to the binary log, but the second statement was not:

UPDATE db1.tb1 SET db1.tbl1.col1=2; UPDATE mysql.user SET mysql.user.Superpriv='Y' WHERE mysql.user.User='user1';

However, the text of the second statement could be wrapped in version-specific comments and thus “hidden” within the text of the first statement so that this new version of the first statement succeeded, and was written in its entireity to the binary log. The new statement containing the necessary portions of the statement affecting the “mysql.user” table wrapped within version-specific comments is shown here:

UPDATE db1.tbl1 /!514900 ,mysql.user / SET db1.tbl1.col1=2 /!514900 ,mysql.user.Superpriv='Y' WHERE mysql.user.User='user1'/;

Thus, a 5.1.48 master would see this statement as identical to the first of the original two statements shown previously (UPDATE db1.tb1 SET db1.tbl1.col1=2). However, the version-specific comments within the statement just shown, when run on the MySQL 5.1.49 slave, were ignored; thus the slave SQL thread would execute the statement, as shown here, with the SUPER privilege, on the slave:

UPDATE db1.tbl1,mysql.user SET db1.tbl1.col1=2,mysql.user.Superpriv='Y' WHERE mysql.user.User='user1';

To fix this issue, the ! (exclamation) character is now stripped from comments prior to statements containing them being applied on replication slaves; thus, version-specific comments that are not applied on the master are treated as normal comments on the slave and also not applied there.

Additional info:

Buffer overflow in the opentable function in sqlbase.cc in MySQL 5.0.x up to 5.0.20 might allow remote attackers to execute arbitrary code via crafted COMTABLEDUMP packets with invalid length values.

MySQL before 5.0.25 and 5.1 before 5.1.12 evaluates arguments of suid routines in the security context of the routine's definer instead of the routine's caller, which allows remote authenticated users to gain privileges through a routine that has been made available using GRANT EXECUTE.

Directory traversal vulnerability in MySQL 5.0 through 5.0.91 and 5.1 before 5.1.47 allows remote authenticated users to bypass intended table grants to read field definitions of arbitrary tables, and on 5.1 to read or delete content of arbitrary tables, via a .. (dot dot) in a table name.

MySQL Server 5.1.x before 5.1.23 and 6.0.x before 6.0.4 does not check the rights of the entity executing BINLOG, which allows remote authorized users to execute arbitrary BINLOG statements.

Multiple SQL injection vulnerabilities in MySQL Eventum 1.5.5 and earlier allow remote attackers to execute arbitrary SQL commands via the (1) isCorrectPassword or (2) userExist function in class.auth.php, getCustomFieldReport function in (4) customfields.php, (5) customfieldsgraph.php, or (6) class.report.php, or the insert function in (7) releases.php or (8) class.release.php.

The mysqlchangedb function in MySQL 5.0.x before 5.0.40 and 5.1.x before 5.1.18 does not restore THD::dbaccess privileges when returning from SQL SECURITY INVOKER stored routines, which allows remote authenticated users to gain privileges.

Buffer overflow in MySQL 5.0 through 5.0.91 and 5.1 before 5.1.47 allows remote authenticated users to execute arbitrary code via a COMFIELDLIST command with a long table name.
