CVE-2024-33603
Published: 30 October 2024
Summary
CVE-2024-33603 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor (CWE-200) vulnerability in Level1 Wbr-6012 Firmware. Its CVSS base score is 5.3 (Medium).
Operationally, ranked in the top 5.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
The LevelOne WBR-6012 router contains an information disclosure vulnerability in its web application. Unauthenticated remote users can retrieve a verbose system log page that exposes sensitive internal details such as memory addresses and the IP addresses of recent login attempts.
An attacker with network access to the device can exploit the flaw without credentials or user interaction to collect this data. Because the router uses IP address as part of its authentication mechanism, the obtained information may enable session hijacking or further targeted attacks against the device.
The associated EPSS score has remained flat at 0.1378 since disclosure, indicating no material increase in observed exploitation interest.

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.
