CVE-2022-24048 is a high-severity vulnerability associated with the MariaDB CONNECT Storage Engine. This vulnerability allows local attackers to escalate privileges on affected installations of MariaDB. The flaw arises from improper validation of the length of user-supplied data during SQL query processing, leading to a stack-based buffer overflow. Successful exploitation requires authentication, enabling attackers to execute arbitrary code in the context of the service account.
The CVSS score for this vulnerability is 7.8, indicating a high severity level, with potential impacts on confidentiality, integrity, and availability being rated as high. Organizations should assess their exposure to this vulnerability and take immediate action to patch affected installations.
Currently, there is no known public exploit available for CVE-2022-24048. However, the lack of effective remediation could lead to significant risks, especially in environments where MariaDB is deployed.
Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability.
Vulnerability Details
The vulnerability allows local attackers to escalate privileges on affected installations of MariaDB. The specific flaw exists within the processing of SQL queries. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer.
The official CVSS 3.1 vector for this vulnerability is: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating that the attack vector is local, the complexity is low, and a low level of privileges is required. The impacts on confidentiality, integrity, and availability are all rated as high.
The affected products are versions of MariaDB prior to 10.2.42, 10.3.33, 10.4.23, 10.5.14, 10.6.6, and 10.7.2, along with version 10.8.0. Additionally, certain versions of Fedora (34, 35, and 36) are also impacted by this vulnerability.
Technical Analysis
The root cause of CVE-2022-24048 is a stack-based buffer overflow due to inadequate validation of user input length. The vulnerability can be exploited by local attackers who can execute SQL queries on the affected MariaDB installations.
The attack vector is local, meaning that the attacker must have access to the system where MariaDB is running. The complexity of the attack is low, requiring only low privileges. User interaction is not required for this vulnerability to be exploited. If successful, the attacker could potentially gain high privileges, leading to significant impacts on confidentiality, integrity, and availability.
Risk & Impact Analysis
Risk to organizations includes the potential for attackers to escalate privileges and execute arbitrary code, which could compromise sensitive data and disrupt services. Given that the attack vector is local, organizations with physical or remote access to the systems running MariaDB should be particularly vigilant.
The urgency for remediation is high, as the potential for an attacker to exploit this vulnerability is significant. The CVSS score reflects a serious risk, and organizations operating vulnerable versions must take immediate action to patch and secure their systems.
