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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
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 5 Jul 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 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 or the CVSS exploit maturity 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

Immediately restrict network access to the /api/admin/user endpoint using firewalls or network segmentation to limit exposure to trusted internal IP addresses only.
Implement strong authentication and authorization controls on the affected API endpoint, ensuring only authorized administrators can access user data.
Monitor API logs for unusual or unauthorized GET requests targeting /api/admin/user to detect potential exploitation attempts.
If possible, disable or remove the vulnerable API endpoint until a vendor patch or update is available.
Engage with the 14Finger vendor or software maintainers to obtain official patches or security updates addressing this vulnerability.
Conduct a thorough audit of all administrative APIs in the environment to verify that similar insecure permission issues do not exist elsewhere.
Educate development and security teams on secure API design principles, particularly enforcing authentication on all sensitive endpoints.
Prepare incident response plans to quickly address any detected exploitation attempts or data breaches related to this vulnerability.

Description

Insecure permissions in the component /api/admin/user of 14Finger v1.1 allows attackers to access all user information via a crafted GET request.

Impact

The primary impact of CVE-2024-37767 is a total breach of user data confidentiality. Attackers exploiting this vulnerability can access sensitive user information without any authentication, potentially leading to identity theft, privacy violations, and further targeted attacks such as phishing or social engineering. Organizations relying on 14Finger v1.1 risk exposure of their user databases, which can damage reputation, incur regulatory penalties (especially under data protection laws like GDPR or CCPA), and result in financial losses. Since the vulnerability does not affect integrity or availability, the system’s operation remains intact, but the data exposure alone is critical. The ease of exploitation (no authentication or user interaction required) increases the likelihood of attacks, especially from opportunistic threat actors scanning for vulnerable endpoints. The absence of known exploits in the wild currently limits immediate widespread impact, but the vulnerability remains a significant risk until remediated. Organizations in sectors handling sensitive user data such as healthcare, finance, and government are particularly vulnerable to the consequences of this data exposure.

Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #21OWASP Top 10 A07:2025: Authentication Failures (opens in a new tab)
The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.
Architecture and Design
Divide the software into anonymous, normal, privileged, and administrative areas. Identify which of these areas require a proven user identity, and use a centralized authentication capability.
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks…
Architecture and Design
Where possible, avoid implementing custom, "grow-your-own" authentication routines and consider using authentication capabilities as provided by the surrounding framework, operating system, or environment.
