Published: 03 May 2024
Summary
CVE-2023-32167 is a medium-severity Path Traversal (CWE-22) vulnerability in Dlink D-View 8. Its CVSS base score is 6.5 (Medium).
Operationally, ranked in the top 1.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
D-Link D-View contains a directory traversal vulnerability in the uploadMib function that permits remote attackers to create or delete arbitrary files on affected installations. The flaw stems from insufficient validation of a user-supplied path before it is used in file operations, allowing actions to occur in the context of the SYSTEM account. Authentication is required to reach the vulnerable code path, and the issue was originally reported as ZDI-CAN-19529.
An authenticated attacker with network access can supply a crafted path to uploadMib and thereby create or remove files anywhere on the system. Successful exploitation yields high impact on integrity and availability without requiring user interaction, corresponding to the CVSS 6.5 rating for this CWE-22 weakness.
Vendor advisories from D-Link (SAP10332) and the Zero Day Initiative (ZDI-23-718) address the issue and direct administrators to apply the patches or mitigations published in those announcements.
EPSS for the CVE rose from lower values to a peak of 0.6793 before settling at the current 0.5585, indicating increased exploitation interest after disclosure.
