CVE-2023-39073Network attack vector

Arbitrary system-file deletion via crafted requests

Published Sep 12, 2023 · Updated Sep 26, 2024

Path traversal in SNMP Web Pro 1.1 allows remote attackers to delete system files through crafted unauthenticated web requests. The web server accepts a request-controlled file reference and performs deletion without confining the path, although the proof of concept is not public. The attack requires no privileges or user interaction; deleted system files leave dependent management functions unavailable.
