An authenticated administrator can manipulate the `snmpget` configuration parameter to execute arbitrary system commands. When the `/about` endpoint is accessed, the application executes the configured binary path via `shell_exec()` without proper validation. This vulnerability leads to complete server compromise, allowing attackers to establish reverse shells, exfiltrate sensitive data, and maintain persistent access.\n\n**Severity:** High (CVSS 7.2)\n**Attack Vector:** Network\n**Privileges Required:** High (Administrator)\n**User Interaction:** None\n**Impact:** Complete system compromise with web server privileges\n\n---\n\n## Details\n\n### Vulnerable Code\n\n**File:** `app/Http/Controllers/AboutController.php`\n**Line:** 85\n\n```php\n'version_netsnmp' => str_replace('version: ', '', \n    rtrim(shell_exec(LibrenmsConfig::get('snmpget', 'snmpget') .
