CVE-2023-39437Network attack vector

Authenticated script execution via unneutralized web content

Published Aug 8, 2023 · Updated Oct 11, 2024

Cross-site scripting in SAP Business One 10.0 allows remote authenticated users to execute script in another user's client. SAP states that attacker-supplied code is inserted into web-page or application content and delivered to the client, but does not identify the affected endpoint, field, or encoding failure. Low-privileged access and victim interaction are required; exploitation exposes or modifies application data and can interrupt service.
