According to its self-reported version, the Tenable SecurityCenter application installed on the remote host is prior to 5.4.0. It is, therefore, affected by multiple vulnerabilities :
An arbitrary code execution vulnerability exists in the bundled version of libcurl due to using an insecure path to look for specific libraries, including the current working directory, which may not be under user control.
A remote attacker can exploit this to inject and execute arbitrary code in the context of the current user.
(CVE-2016-4802)
Multiple flaws exist in the bundled version of libssh due to a failure to securely generate Diffie-Hellman secret keys. A man-in-the-middle attacker can exploit these flaws to intercept and decrypt SSH sessions.
(CVE-2016-0739, CVE-2016-0787)
An integer overflow condition exists in the bundled version of libcurl due to improper validation of user-supplied input when handling ‘timeval’. An attacker can exploit this to have an unspecified impact.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
