A recently identified vulnerability in the MySQL Server product of Oracle MySQL allows for significant risk to organizations relying on affected versions. This vulnerability allows high privileged attackers with network access via multiple protocols to compromise MySQL Server, specifically versions 8.0.0 through 8.0.42. The nature of this vulnerability is such that successful exploitation can result in a denial of service (DoS), causing the server to hang or crash. With a CVSS score of 4.9, this vulnerability has been classified as medium severity, but the implications for availability make it a pressing concern.
Organizations utilizing these versions should be aware that this vulnerability is easily exploitable, emphasizing the need for immediate action. Given its potential impact on system availability, organizations should prioritize patching as soon as possible to prevent unauthorized access and operational disruptions.
The urgency for defenders cannot be overstated. Organizations should closely monitor their environments for any signs of exploitation and ensure that they are applying the necessary patches to mitigate this risk. In light of the increasing sophistication of attacks, failing to address this vulnerability could lead to severe operational consequences.
In summary, CVE-2025-53023 presents a medium-severity risk that requires immediate attention. Organizations are urged to implement the provided patches and maintain vigilance in monitoring their MySQL Server environments.
Vulnerability Details
This vulnerability allows high privileged attackers with network access via multiple protocols to compromise MySQL Server. The affected versions are 8.0.0 to 8.0.42, and the vulnerability has been assigned a CVSS 3.1 Base Score of 4.9, indicating medium severity. The primary impact of this vulnerability is on availability, as it can lead to a denial of service.
The CWE classification for this vulnerability is CWE-400, indicating that it is a resource exhaustion issue. Organizations should be particularly cautious as exploitation could lead to critical service interruptions.
Technical Analysis
The root cause of this vulnerability stems from improper handling of network requests that can lead to resource exhaustion. The attack vector is network-based, meaning that an attacker does not need physical access to exploit this vulnerability. The complexity of the attack is rated as low, requiring high privileges, but no user interaction is needed to exploit it.
The impacts on confidentiality and integrity are rated as none, but the availability impact is high, which means successful exploitation can lead to significant service disruptions.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-53023 is moderate, with potential for widespread impact due to the commonality of MySQL Server usage in various applications. The blast radius of a successful attack could extend to all connected systems reliant on the MySQL Server, leading to extensive downtime and operational challenges.
Given the CVSS score of 4.9 and the absence of known exploitation in the KEV database, organizations should still treat this vulnerability as a priority due to its potential impact on availability. Immediate patching is essential to mitigate the risks associated with this vulnerability.
