The version of cacti installed on the remote host is prior to 1.1.19-5.23. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1862 advisory.
Cacti is an open source operational monitoring and fault management framework. In Cacti 1.2.24, under certain conditions, an authenticated privileged user, can use a malicious string in the SNMP options of a Device, performing command injection and obtaining remote code execution on the underlying server. The lib/snmp.php
file has a set of functions, with similar behavior, that accept in input some variables and place them into an exec
call without a proper escape or validation. This issue has been addressed in version 1.2.25. Users are advised to upgrade. There are no known workarounds for this vulnerability.
(CVE-2023-39362)
Cacti is an open source operational monitoring and fault management framework. In Cacti 1.2.24, users with console access can be redirected to an arbitrary website after a change password performed via a specifically crafted URL. The auth_changepassword.php
file accepts ref
as a URL parameter and reflects it in the form used to perform the change password. It’s value is used to perform a redirect via header
PHP function. A user can be tricked in performing the change password operation, e.g., via a phishing message, and then interacting with the malicious website where the redirection has been performed, e.g., downloading malwares, providing credentials, etc. This issue has been addressed in version 1.2.25. Users are advised to upgrade. There are no known workarounds for this vulnerability. (CVE-2023-39364)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
