Vulnerability Details
The official description states that MariaDB Server v10.9 and below was discovered to contain a segmentation fault via the component sql/item_func.cc:148. The vulnerability is classified under the high severity category with a CVSS score of 7.5, indicating a serious threat to database availability.
This vulnerability is attributed to configurations within the MariaDB software where certain input can lead to a crash, impacting service availability. The affected versions include MariaDB Server versions prior to 10.3.35, from 10.4.0 to 10.4.25, from 10.5.0 to 10.5.16, from 10.6.0 to 10.6.8, and from 10.7.0 to 10.7.4.
This vulnerability falls under the category of availability issues with a high impact as it can lead to service downtime. The publication date of this vulnerability was April 14, 2022, and organizations are advised to take immediate steps to mitigate the risks associated with this threat.
Technical Analysis
The root cause of CVE-2022-27449 is a flaw in the MariaDB Server code that leads to a segmentation fault when the sql/item_func.cc component processes certain inputs. This vulnerability has a network attack vector, allowing remote attackers to exploit it without requiring physical access to the server.
The attack complexity is classified as low, meaning that attackers do not require advanced skills to exploit this vulnerability. No user interaction is needed, as the vulnerability can be triggered automatically by sending crafted requests to the server.
The vulnerability impacts availability, as successful exploitation can crash the database service, leading to significant disruptions. Confidentiality and integrity are not impacted, which means that data remains secure, but the system may become unavailable to legitimate users.
Risk & Impact Analysis
The real-world risk associated with CVE-2022-27449 is substantial, particularly for organizations relying heavily on MariaDB for critical database operations. The availability impact, categorized as high, suggests that the potential for service interruptions is significant. Organizations should assess the blast radius of this vulnerability, as the impact may extend beyond the affected database to other interconnected systems.
Given the attack vector and low complexity, the urgency for organizations to address this vulnerability is high. The CVSS score of 7.5 indicates that organizations should prioritize patching in their security cycles to mitigate potential risks.
