CVE-2023-32165
Published: 03 May 2024
Summary
CVE-2023-32165 is a critical-severity Path Traversal (CWE-22) vulnerability in Dlink D-View 8. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 2.8% 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 TftpReceiveFileHandler class that permits remote code execution. The flaw stems from insufficient validation of user-supplied paths before they are used in file operations, allowing an unauthenticated attacker to write or execute files on the target system. The issue was originally reported as ZDI-CAN-19497 and carries a CVSS 3.0 score of 9.8.
Remote attackers can exploit the vulnerability over the network without authentication or user interaction to achieve arbitrary code execution in the context of the SYSTEM account. Successful exploitation grants full control over the affected D-View installation, including the ability to install programs, view or modify data, and create new accounts.
D-Link has published security announcement SAP10332 and the Zero Day Initiative has released advisory ZDI-23-716, both of which address the issue. The current EPSS score of 0.3532, with a recorded peak of 0.4344, indicates measurable post-disclosure exploitation interest.
