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: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
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: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to 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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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 26 Oct 2026.

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. Immediate network-level controls: Restrict network access to MySQL Connectors by implementing firewall rules and network segmentation to limit exposure only to trusted hosts and internal networks. 2. Monitor and log all database connector traffic for unusual update, insert, or delete operations to detect potential exploitation attempts early. 3. Apply principle of least privilege on database accounts used by connectors to minimize the impact of unauthorized data manipulation. 4. Disable or restrict unused MySQL Connector protocols and interfaces to reduce the attack surface. 5. Stay updated with Oracle’s security advisories and apply patches as soon as they become available. 6. Conduct thorough security assessments and penetration testing focused on MySQL Connectors to identify and remediate any configuration weaknesses. 7. Employ intrusion detection/prevention systems (IDS/IPS) tuned to detect anomalous MySQL Connector activities. 8. Educate IT and security teams about this vulnerability and ensure incident response plans include scenarios involving database connector compromise. 9. Consider deploying Web Application Firewalls (WAFs) or database activity monitoring tools that can enforce stricter access controls and detect suspicious queries. 10. Review and update backup and recovery procedures to ensure rapid restoration in case of data integrity compromise or DoS incidents.

Description

Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/ODBC). Supported versions that are affected are 9.0.0 and prior. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise MySQL Connectors. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of MySQL Connectors accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of MySQL Connectors. CVSS 3.1 Base Score 6.5 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L).

Impact

For European organizations, the vulnerability poses a risk of unauthorized data manipulation—such as unauthorized updates, inserts, or deletions—potentially compromising the integrity of business-critical data. This can lead to corrupted records, inaccurate reporting, or compromised transactional systems. The partial denial of service can disrupt application availability, affecting business continuity and service delivery. Sectors such as finance, healthcare, manufacturing, and public administration, which often rely on MySQL databases and connectors for backend data operations, are particularly vulnerable. The unauthenticated nature of the attack and network accessibility increase the risk of exploitation by external threat actors, including cybercriminals and state-sponsored groups. Given the interconnected nature of European IT infrastructures and regulatory requirements like GDPR, data integrity issues could also lead to compliance violations and reputational damage. The medium severity score reflects moderate but tangible risks that require prompt attention to avoid escalation or chained attacks.

CWE-863Incorrect Authorization (opens in a new tab)
Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #17OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
