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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
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 2 Sep 2025
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

To mitigate this vulnerability, European organizations should: 1) Immediately review and restrict access to the CData API Server, ensuring that only trusted and necessary users have authentication credentials. 2) Apply the principle of least privilege to the NETWORK SERVICE account and related service accounts to minimize accessible data. 3) Monitor and audit API Server logs for unusual access patterns or file requests indicative of exploitation attempts. 4) Disable or reconfigure the MySQL client option that allows the server to request local files if possible, or apply vendor-provided patches once available. 5) Implement network segmentation to isolate the API Server from sensitive internal resources. 6) Conduct regular credential hygiene practices, including multi-factor authentication and periodic password changes, to reduce the risk of credential compromise. 7) Engage with CData support for updates or workarounds and stay informed about patch releases.

Description

CData API Server MySQL Misconfiguration Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of CData API Server. Authentication is required to exploit this vulnerability. The specific flaw exists within the usage of MySQL connections. When connecting to a MySQL server, the product enables an option that gives the MySQL server permission to request local files from the MySQL client. An attacker can leverage this vulnerability to disclose information in the context of NETWORK SERVICE. Was ZDI-CAN-23950.

Impact

For European organizations using CData API Server, this vulnerability poses a risk of sensitive data leakage from the server environment, particularly data accessible by the NETWORK SERVICE account. This could include configuration files, credentials, or other sensitive information stored locally. Such information disclosure could facilitate further attacks, including privilege escalation or lateral movement within the network. Organizations in sectors with stringent data protection regulations, such as finance, healthcare, and government, may face compliance risks if sensitive personal or business data is exposed. The requirement for authentication reduces the risk from external attackers but raises concerns about insider threats or compromised credentials. Given the widespread use of MySQL and API integration in European enterprises, the vulnerability could impact data confidentiality and trust in API services, potentially disrupting business operations and damaging reputations.
