CVE-2022-33151Network attack vector

Browser script execution via undisclosed parameters

Published Aug 18, 2022 · Updated Aug 3, 2024

Cross-site scripting in specific Cybozu Office 10.0.0 through 10.8.5 parameters allows remote attackers to inject arbitrary script. The vendor has not disclosed the affected parameters or the input-handling operation that permits script injection and withholds reproduction steps to limit abuse. Exploitation requires a logged-in user to interact with attacker-controlled input, after which script runs in that user's browser and can read or modify data in that session.
