CVE-2024-21262 is a medium-severity vulnerability affecting Oracle MySQL Connectors, specifically the Connector/ODBC component. This vulnerability allows unauthenticated attackers with network access to exploit vulnerabilities in MySQL Connectors, impacting versions 9.0.0 and prior. The CVSS 3.1 base score for this vulnerability is 6.5, indicating moderate risk. Exploitation can lead to unauthorized updates, inserts, or deletions of accessible data, as well as partial denial of service (partial DOS). Organizations should prioritize patching immediately.
The risk to organizations includes unauthorized access to sensitive data and potential disruption of services due to the denial of service capabilities. Given the exploitability of this vulnerability, it is crucial for organizations using affected versions to take immediate action to mitigate risks.
This vulnerability has been assigned a CVSS vector of (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L), indicating low attack complexity and no required privileges or user interaction. The urgency for defenders is heightened as successful exploitation can lead to significant operational risks.
Organizations should assess their exposure and implement the necessary patches to safeguard their MySQL Connectors from potential attacks.
Vulnerability Details
This vulnerability allows unauthenticated attackers with network access via multiple protocols to compromise Oracle MySQL Connectors. Supported versions that are affected are 9.0.0 and prior. The CVSS 3.1 base score of 6.5 reflects its impact on integrity and availability.
The integrity impact is classified as low, while the availability impact is also low, indicating that while the effects may not be catastrophic, they can still compromise the integrity of the data and services.
The vulnerability was published on October 15, 2024, and is classified under CWE-863, which pertains to inappropriate authorization. Organizations are encouraged to review their systems for compliance and apply necessary patches.
Technical Analysis
The root cause of CVE-2024-21262 pertains to a flaw in the authorization mechanisms of MySQL Connectors, which does not sufficiently restrict unauthenticated network access. This vulnerability can be exploited remotely, requiring no privileges or user interaction, making it particularly concerning.
The attack vector is network-based, allowing potential attackers to exploit the vulnerability from anywhere with access to the network. The attack complexity is low, meaning that even less sophisticated attackers may successfully exploit the vulnerability. The impacts on confidentiality are non-existent, while the integrity and availability impacts are classified as low.
Organizations should consider implementing strict network controls to limit access to vulnerable systems and regularly monitor for unusual activity that could indicate exploitation attempts.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2024-21262 is significant. Organizations using affected versions of MySQL Connectors must understand the potential for unauthorized data manipulation and service disruptions. The blast radius includes any system relying on these connectors, making it critical to address.
Given the CVSS score of 6.5, the urgency for organizations is medium. It is imperative that affected organizations prioritize patching during their next update cycle to mitigate the risk of exploitation.
