Vulnerability Details
MariaDB Server v10.9 and below was discovered to contain a segmentation fault via the component sql/item_cmpfunc.cc. This vulnerability allows an attacker to potentially disrupt services, leading to availability issues.
The CVSS score for this vulnerability is 7.5, indicating a high severity level. The vulnerability has a CVSS vector string of CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H, with the following characteristics:
Characteristic | Value |
|---|---|
Attack Vector | Network |
Attack Complexity | Low |
Privileges Required | None |
User Interaction | None |
Availability Impact | High |
Technical Analysis
The root cause of CVE-2022-27452 lies within the MariaDB Server's handling of SQL functions. A segmentation fault occurs due to improper handling of certain conditions in the sql/item_cmpfunc.cc component. This fault can be triggered by sending specially crafted requests to the server, which may lead to a denial of service.
The attack vector is network-based, meaning an attacker does not need physical access to the server to exploit this vulnerability. With low attack complexity and no required user interaction, this vulnerability poses a significant risk to organizations running affected versions of MariaDB.
In terms of impacts, the vulnerability primarily affects availability, which can disrupt services and operations. Confidentiality and integrity impacts are reported as none, indicating that this vulnerability does not expose sensitive information or compromise data integrity.
Risk & Impact Analysis
The risk to organizations includes potential downtime, which can lead to significant operational disruptions. Given the high severity and availability score of this vulnerability, organizations should assess their exposure and implement necessary mitigations.
With an EPSS score of 0.00138, indicating a low probability of exploitation, organizations should still be proactive, as the impact of a successful exploit could be severe. The CVSS score of 7.5 also indicates that this vulnerability should be addressed as part of the priority patch cycle.
Organizations relying on MariaDB should monitor their systems for abnormal behavior and apply patches as soon as they are available. The potential blast radius of this vulnerability necessitates an immediate response to mitigate risks.
