DescriptionCVE.org

Certain HP DeskJet All in One devices may be vulnerable to remote code execution caused by a buffer overflow when specially crafted Web Services for Devices (WSD) scan requests are improperly validated and handled by the MFP.

WSD Scan is a Microsoft Windows-based network scanning protocol that allows a PC to discover scanners (and MFPs) on a network and send scan jobs to them without requiring vendor specific drivers or utilities.
