CVE-2023-52970 is a vulnerability in MariaDB Server that affects versions 10.4 through 10.5.*, 10.6 through 10.6.*, 10.7 through 10.11.*, 11.0 through 11.0.*, and 11.1 through 11.4.*. This vulnerability allows the server to crash due to a flaw in the Item_direct_view_ref::derived_field_transformer_for_where function. With a CVSS score of 4.9, it is classified as medium severity, indicating that while it may not be critical, it still poses a significant risk to service availability.
The vulnerability is particularly concerning because it has been classified under CWE-1038, which relates to inappropriate handling of data types. As a result, it can lead to service disruptions, impacting the availability of the database service. Organizations using affected versions should be aware of the potential impact on their operations.
Currently, there is no known exploit for this vulnerability, and it has not been added to the Known Exploited Vulnerabilities (KEV) catalog. However, the medium severity and the potential for crashes mean that organizations should remain vigilant.
Given the availability impact associated with this vulnerability, organizations should prioritize monitoring for updates and patches related to MariaDB Server. Organizations are advised to address this vulnerability in their regular patch management processes.
Vulnerability Details
The official description of CVE-2023-52970 states that it affects MariaDB Server versions 10.4 through 10.5.*, 10.6 through 10.6.*, 10.7 through 10.11.*, 11.0 through 11.0.*, and 11.1 through 11.4.*. The vulnerability occurs in the Item_direct_view_ref::derived_field_transformer_for_where function, leading to server crashes.
The CVSS score of 4.9 indicates a medium severity, with the following metrics: attack vector is NETWORK, attack complexity is LOW, privileges required are HIGH, and the user interaction is NONE. The impact on availability is HIGH, while there are no impacts on confidentiality or integrity.
Technical Analysis
The root cause of this vulnerability lies in incorrect handling of certain data types within the MariaDB Server. When certain derived tables are processed, it can lead to conditions where the server experiences crashes. The attack vector is through the network, which means an attacker could potentially exploit this vulnerability remotely, albeit with high privileges required.
Attack complexity is low, and no user interaction is required for the attack to succeed, making it a significant concern for database administrators. While the integrity and confidentiality impacts are non-existent, the availability impact is severe, as it could disrupt database operations and lead to downtime.
Risk & Impact Analysis
Risk to organizations includes potential service disruptions and availability issues due to server crashes. This vulnerability could be particularly impactful in environments that rely heavily on MariaDB for operational processes, leading to interruptions in service delivery.
A medium CVSS score indicates that organizations should schedule remediation in their patch cycles. Although it has not been classified as actively exploited, the potential for service disruption makes it essential for organizations to monitor their systems closely and prepare for any forthcoming patches.
