Synopsis
The remote database server is affected by multiple vulnerabilities.
Description
The version of MySQL running on the remote host is 5.5.x prior to 5.5.55. It is, therefore, affected by multiple vulnerabilities :
- A use-after-free error exists in the mysql_prune_stmt_list() function in client.c that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2017-3302)
- An authentication information disclosure vulnerability, known as Riddle, exists due to authentication being performed prior to security parameter verification. A man-in-the-middle (MitM) attacker can exploit this vulnerability to disclose sensitive authentication information, which the attacker can later use for authenticating to the server. (CVE-2017-3305)
- Multiple unspecified flaws exist in the DML subcomponent that allow an authenticated, remote attacker to cause a denial of service condition. (CVE-2017-3308, CVE-2017-3456)
- Multiple unspecified flaws exist in the Optimizer subcomponent that allow an authenticated, remote attacker to cause a denial of service condition.
(CVE-2017-3309, CVE-2017-3453)
- An unspecified flaw exists in the Thread Pooling subcomponent that allows an unauthenticated, remote attacker to update, insert, or delete data contained in the database. (CVE-2017-3329)
- Multiple unspecified flaws exist in the 'Security: Privileges' subcomponent that allow an authenticated, remote attacker to cause a denial of service condition. (CVE-2017-3461, CVE-2017-3462, CVE-2017-3463)
- An unspecified flaw exists in the DDL subcomponent that allows an authenticated, remote attacker to update, insert, or delete data contained in the database.
(CVE-2017-3464)
- An unspecified flaw exists in the 'Client mysqldump' subcomponent that allows an authenticated, remote attacker to execute arbitrary code. (CVE-2017-3600)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to MySQL version 5.5.55 or later.
