CVE-2023-39593:
MariaDB Server vulnerability analysis and mitigation
Overview
A vulnerability identified as CVE-2023-39593 affects MariaDB v10.5, specifically in the sys_exec function. The vulnerability allows authenticated attackers to execute arbitrary commands with elevated privileges. However, this vulnerability is disputed by the MariaDB Foundation, which states that no privilege boundary is crossed (NVD, Red Hat).
Technical details
The vulnerability is related to insecure permissions in the sys_exec function of MariaDB v10.5. According to the CVSS v3.1 scoring by CISA-ADP, the vulnerability has a base score of 5.6 (MEDIUM) with the following vector: CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:L/A:L. The vulnerability is classified under CWE-94 (Improper Control of Generation of Code) (NVD).
Impact
If exploited, the vulnerability could allow authenticated attackers to execute arbitrary commands with elevated privileges in certain configurations. The potential impact includes unauthorized command execution and system compromise, though this is limited by the requirement of authentication and the disputed nature of the privilege escalation (Red Hat).
Mitigation and workarounds
Currently, specific mitigation information is not widely available. The disputed nature of the vulnerability suggests that proper configuration and access control measures may be sufficient to prevent exploitation. Organizations should carefully evaluate their MariaDB deployments and ensure proper access controls are in place (NVD).
