The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has postgresql packages installed that are affected by a vulnerability:

  • A vulnerability was found in libpq, the default PostgreSQL client library where libpq failed to properly reset its internal state between connections. If an affected version of libpq were used with host or hostaddr connection parameters from untrusted input, attackers could bypass client-side connection security features, obtain access to higher privileged connections or potentially cause other impact through SQL injection, by causing the PQescape() functions to malfunction.
    (CVE-2018-10915)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
