CVE-2023-35175

Code execution via Web Service Eventing SSRF

Published Jun 30, 2023 · Updated Dec 4, 2024

SSRF in HP LaserJet Pro firmware before 002_2322C allows physically proximate attackers to execute code through Web Service Eventing. HP identifies the Web Service Eventing model as the vulnerable locus but has not published the endpoint, request field, or failed destination-validation operation. No privileges or user interaction are required, and successful exploitation permits code execution or information disclosure on the printer.
