Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Command Injection

EUVDB-ID: #VU51645

Risk: High

CVSSv4.0: 8.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]

CVE-ID: CVE-2021-27928

CWE-ID: CWE-77 - Command injection

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to execute arbitrary commands on the target system.

The vulnerability exists due to improper input validation in the "wsrep_provider" and "wsrep_notify_cmd" parameters. A remote attacker can pass specially crafted data to the application and execute arbitrary commands on the target system.

Mitigation

Install updates from vendor's repository.

2) OS Command Injection

EUVDB-ID: #VU49122

Risk: High

CVSSv4.0: 7.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2020-15180

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.

The vulnerability exists due to improper input validation within the wsrep_sst_method method in the mysql-wsrep component of mariadb. A remote unauthenticated attacker can pass specially crafted data to the application and execute arbitrary OS commands on galera cluster node.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Install updates from vendor's repository.
