## Affected

- StreamSoft PingTools Network Utilities: 4.64

## Description

PingTools Network Utilities 4.64 contains an OS command injection vulnerability in the Host field of a Watcher ICMP service. The application appends the attacker-controlled Host value to a ping command, serializes the command as a single string, and executes it through sh -c. A local attacker who can create or modify a Watcher service can inject shell syntax and execute arbitrary commands with the PingTools application UID and its granted Android permissions.
