Description
The Epson Stylus SX510W embedded web management service fails to properly handle consecutive ampersand characters in query parameters when accessing /PRESENTATION/HTML/TOP/INDEX.HTML. A remote attacker can send a malformed request that triggers improper input parsing or memory handling, resulting in the printer process shutting down or powering off, causing a denial of service condition.
