This vulnerability allows MariaDB Server versions 10.4 through 10.5.*, 10.6 through 10.6.*, 10.7 through 10.11.*, and 11.0 through 11.0.* to crash unexpectedly, resulting in an empty backtrace log. The root cause may relate to functions such as make_aggr_tables_info and optimize_stage2. The vulnerability has been assigned a CVSS score of 4.9, indicating a medium severity level, which necessitates prompt attention from organizations using affected versions.
Risk to organizations includes potential downtime and disruption of database services, which can hinder operational capabilities. The crash behavior, if exploited, could lead to significant availability issues for affected systems. Given the exploitability score of 1.2, this vulnerability should not be overlooked.
Organizations should prioritize patching immediately. Ensuring that MariaDB servers are updated to the latest versions can mitigate the risk associated with this vulnerability.
Currently, no public exploit has been confirmed, but organizations must remain vigilant and monitor for updates regarding this vulnerability.
Vulnerability Details
The official CVE description states that MariaDB Server can crash under certain conditions, leading to empty backtrace logs. This issue directly impacts availability, as systems may become unresponsive without adequate logging to diagnose the failure.
This vulnerability falls under the CWE-1038 classification, which denotes a risk related to incorrect handling of function calls. The CVSS score of 4.9 indicates a medium severity vulnerability, which is critical for organizations relying on stable database operations.
Organizations using affected versions of MariaDB Server should ensure they are aware of this vulnerability and take appropriate actions to mitigate potential risks.
Technical Analysis
The root cause of this vulnerability appears to be related to specific database operations that lead to crashes. The attack vector is classified as network, meaning that it can be exploited remotely. The complexity of the attack is low, and it requires high privileges to exploit, indicating that while it is not easily accessible, the potential impact is significant.
No user interaction is required to trigger this vulnerability, which increases the risk it poses to organizations. The confidentiality impact is none, while the integrity impact is also none; however, the availability impact is high, as the crash can lead to a complete denial of service.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is significant, especially for organizations that heavily rely on database services for their operations. The potential for cascading failures affecting dependent systems heightens the urgency for remediation.
Organizations should consider the blast radius of this vulnerability, as the impact could extend beyond the immediate database service to other integrated applications and systems.
Based on the CVSS score, this vulnerability should be addressed in the priority patch cycle. Given the medium severity level, organizations should not delay in implementing fixes.
