Published: 04 April 2024
Summary
CVE-2024-3274 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor (CWE-200) vulnerability in Dlink (inferred from references). Its CVSS base score is 5.3 (Medium).
Operationally, ranked in the top 1.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The vulnerability CVE-2024-3274 is an information disclosure flaw (CWE-200) affecting the unsupported D-Link DNS-320L, DNS-320LW, and DNS-327L network-attached storage devices up to 20240403. It exists in an unknown function of the /cgi-bin/info.cgi file inside the HTTP GET Request Handler component; manipulation of requests to this endpoint exposes sensitive data.
An unauthenticated remote attacker can trigger the issue over the network with no user interaction required, achieving limited confidentiality impact as reflected in its CVSS 5.3 score. Public exploit code has already been released, allowing straightforward remote information gathering against any exposed instances of these end-of-life products.
D-Link’s advisory SAP10383 and vendor statements confirm the devices are no longer supported, explicitly advising that they should be retired and replaced rather than patched.
The associated EPSS score is 0.5787 with no material post-disclosure rise, while the public proof-of-concept is hosted on GitHub.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Automated marking applies security attributes to system outputs, making it harder for attackers to exploit unmarked sensitive information leading to unauthorized exposure.
Proper attribute retention and permitted-value enforcement limits unauthorized actors from accessing sensitive information lacking correct labels.
Prevents unauthorized exposure of sensitive information by prohibiting untrusted external systems from processing or storing it.
By enforcing authorization matching prior to sharing, the control reduces the risk of exposing sensitive information to unauthorized actors.
Review and removal of nonpublic information from publicly accessible systems directly prevents exposure of sensitive data to unauthorized actors.
Data mining protection mechanisms detect and block unauthorized bulk extraction of sensitive data, directly mitigating exposure to unauthorized actors.
Literacy training teaches users to recognize and avoid actions that result in unauthorized exposure of sensitive information.
Retaining and monitoring training records confirms personnel have completed privacy and security awareness training on handling sensitive data, reducing the chance of unauthorized exposure due to lack of knowledge.
