Is this vulnerability remotely exploitable?

Yes. As long as the vulnerable `ping.php` endpoint is reachable over the network, an attacker can exploit it remotely by sending crafted requests containing malicious `ping` or `socket` parameter values.

What level of access does an attacker need to exploit this issue?

The attacker typically only needs network access to the Pinger 1.0 application; no prior authentication is necessarily required unless the endpoint is restricted by the deployment. The commands execute with the privileges of the web server or PHP process.

What is the safest general fix pattern for this vulnerability?

The most robust fix is to remove shell-based command execution entirely and implement the required functionality using safe, language-native APIs for network probing. If external commands must be used, they should be invoked without a shell, with strict allowlist validation on inputs and arguments passed as separate parameters rather than concatenated strings.
