The remote NewStart CGSL host, running version MAIN 6.02, has mariadb-connector-c packages installed that are affected by multiple vulnerabilities:
Vulnerability in the MySQL Client product of Oracle MySQL (component: C API). Supported versions that are affected are 5.6.47 and prior, 5.7.29 and prior and 8.0.18 and prior. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise MySQL Client.
Successful attacks of this vulnerability can result in unauthorized read access to a subset of MySQL Client accessible data. CVSS 3.0 Base Score 3.7 (Confidentiality impacts). CVSS Vector:
(CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N). (CVE-2020-2922)
Vulnerability in the MySQL Client product of Oracle MySQL (component: C API). Supported versions that are affected are 5.6.47 and prior, 5.7.27 and prior and 8.0.17 and prior. Difficult to exploit vulnerability allows low privileged attacker with network access via multiple protocols to compromise MySQL Client.
Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Client. CVSS 3.0 Base Score 5.3 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H). (CVE-2020-2752)
Vulnerability in the MySQL Client product of Oracle MySQL (component: C API). Supported versions that are affected are 5.6.46 and prior, 5.7.28 and prior and 8.0.18 and prior. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise MySQL Client.
Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Client. CVSS 3.0 Base Score 5.9 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H). (CVE-2020-2574)
libmariadb/mariadb_lib.c in MariaDB Connector/C before 3.1.8 does not properly validate the content of an OK packet received from a server. NOTE: although mariadb_lib.c was originally based on code shipped for MySQL, this issue does not affect any MySQL components supported by Oracle. (CVE-2020-13249)
Vulnerability in the MySQL Client product of Oracle MySQL (component: C API). Supported versions that are affected are 5.6.47 and prior, 5.7.29 and prior and 8.0.19 and prior. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise MySQL Client.
Successful attacks of this vulnerability can result in unauthorized read access to a subset of MySQL Client accessible data. CVSS 3.1 Base Score 3.7 (Confidentiality impacts). CVSS Vector:
(CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N). (CVE-2021-2007)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
