The version of F5 Networks BIG-IP installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the K53225395 advisory.
A flaw was found in c-ares library, where a missing input validation check of host names returned by DNS (Domain Name Servers) can lead to output of wrong hostnames which might potentially lead to Domain Hijacking. The highest threat from this vulnerability is to confidentiality and integrity as well as system availability. (CVE-2021-3672)
Node.js before 16.6.0, 14.17.4, and 12.22.4 is vulnerable to Remote Code Execution, XSS, Application crashes due to missing input validation of host names returned by Domain Name Servers in Node.js dns library which can lead to output of wrong hostnames (leading to Domain Hijacking) and injection vulnerabilities in applications using the library. (CVE-2021-22931)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
