Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Security: Privileges). Supported versions that are affected are 5.6.44 and prior and 5.7.18 and prior. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of MySQL Server accessible data. CVSS 3.0 Base Score 2.7 (Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N).

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Security: Privileges).
    Supported versions that are affected are 5.6.44 and prior and 5.7.18 and prior. Easily exploitable     vulnerability allows high privileged attacker with network access via multiple protocols to compromise     MySQL Server. Successful attacks of this vulnerability can result in unauthorized update, insert or delete     access to some of MySQL Server accessible data. (CVE-2019-2730)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2886 advisory.

    MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon, mysqld,     and many client programs.

    The following packages have been upgraded to a later upstream version: rh-mysql57-mysql (5.7.19).

    Security Fix(es):

    * An integer overflow flaw leading to a buffer overflow was found in the way MySQL parsed connection     handshake packets. An unauthenticated remote attacker with access to the MySQL port could use this flaw to     crash the mysqld daemon. (CVE-2017-3599)

    * It was discovered that the mysql and mysqldump tools did not correctly handle database and table names     containing newline characters. A database user with privileges to create databases or tables could cause     the mysql command to execute arbitrary shell or SQL commands while restoring database backup created using     the mysqldump tool. (CVE-2016-5483, CVE-2017-3600)

    * It was discovered that the mysqld_safe script honored the ledir option value set in a MySQL     configuration file. A user able to modify one of the MySQL configuration files could use this flaw to     escalate their privileges to root. (CVE-2017-3291)

    * Multiple flaws were found in the way the mysqld_safe script handled creation of error log file. The     mysql operating system user could use these flaws to escalate their privileges to root. (CVE-2017-3312)

    * This update fixes several vulnerabilities in the MySQL database server. Information about these flaws     can be found on the Oracle Critical Patch Update Advisory pages listed in the References section.

    Bug Fix(es):

    * Prior to this update, the scl macros were not set for the rh-mysql57-mysqld@.service file, which     consequently made the service file unusable. This bug has been fixed, and rh-mysql57-mysqld@.service now     works as expected. (BZ#1452511)

    * Previously, the md5() function was blocked by MySQL in FIPS mode because the MD5 hash algorithm is     considered insecure. Consequently, the mysqld daemon failed with error messages when FIPS mode was     enabled. With this update, md5() is allowed in FIPS mode for non-security operations. Note that users are     able to use md5() for security purposes but such usage is not supported by Red Hat. (BZ#1452514)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Oracle reports :

This Critical Patch Update contains 45 new security fixes for Oracle MySQL. 4 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials.

The version of MySQL running on the remote host is 5.7.x prior to 5.7.19. It is, therefore, affected by multiple vulnerabilities :

  - An unspecified flaw exists in the UDF component that     allows an authenticated, remote attacker to cause a     denial of service condition. (CVE-2017-3529)

  - An unspecified flaw exists in the Memcached component     that allows an unauthenticated, remote attacker to     impact integrity and availability. (CVE-2017-3633)
