Network Scanner Tool Lite
Monthly
Sharp Corporation's Network Scanner Tool and Network Scanner Tool Lite expose unauthenticated, unlimited file upload endpoints by default, enabling two distinct attack outcomes against any PC running the software in its initial configuration. An unauthenticated network attacker can flood the host with uploaded files to exhaust disk or system resources, causing a denial-of-service condition; separately, a threat actor can stage malicious executables that a local PC user may be socially engineered into running, enabling downstream attacks against other systems. No public exploit code has been identified at time of analysis, and no CISA KEV listing exists, though the default-insecure nature and zero authentication requirement lower the barrier to exploitation significantly.
