Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
Privileges Required: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 15 Oct 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

1. Restrict network access to MySQL servers, especially limiting high-privilege user connections to trusted hosts and networks only. 2. Enforce the principle of least privilege by auditing and minimizing high-privilege accounts that can access MySQL over the network. 3. Monitor telemetry data flows and logs for unusual access patterns or unauthorized read attempts. 4. Apply Oracle's security patches promptly once they are released for the affected MySQL versions. 5. Use network segmentation and firewall rules to isolate MySQL servers from untrusted networks. 6. Implement strong authentication and encryption for MySQL connections to reduce risk of credential compromise. 7. Regularly review and update MySQL server configurations to disable unnecessary telemetry features if possible. 8. Conduct internal penetration testing focusing on privilege escalation and network access controls around MySQL servers. 9. Maintain up-to-date asset inventories to identify all MySQL instances and their versions for targeted patching. 10. Educate administrators about the risks of high-privilege network access and encourage adherence to security best practices.

Description

Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Telemetry). Supported versions that are affected are 8.4.2 and prior and 9.0.1 and prior. Difficult to exploit vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized read access to a subset of MySQL Server accessible data. CVSS 3.1 Base Score 2.2 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:N/A:N).

Impact

For European organizations, the impact of CVE-2024-21244 is relatively low due to the limited confidentiality exposure and the high privilege and network access requirements for exploitation. However, organizations with critical MySQL Server deployments that handle sensitive telemetry or operational data could face unauthorized disclosure of some internal metrics or server data subsets. This could aid attackers in reconnaissance or lateral movement within a network. The lack of integrity or availability impact means business operations are unlikely to be disrupted directly by this vulnerability. Nonetheless, in sectors such as finance, healthcare, or critical infrastructure where MySQL is widely used, even limited data exposure can have compliance and reputational consequences under GDPR and other regulations. The difficulty of exploitation reduces the likelihood of widespread attacks, but targeted attacks against high-value assets remain a concern. European organizations should consider this vulnerability in their risk assessments, especially where MySQL servers are exposed to internal or external networks with users holding elevated privileges. The absence of known exploits in the wild currently lowers immediate risk but does not eliminate the need for vigilance.
