The duration function in the moment package before 2.11.2 for Node.js allows remote attackers to cause a denial of service (CPU consumption) via a long string, aka a "regular expression Denial of Service (ReDoS)."

The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4786-1 advisory.

    It was discovered that Moment.js mishandled certain regular expressions. An attacker could use this     vulnerability to cause a denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to its self-reported version, the Tenable Nessus application running on the remote host is prior to 8.3.0. It is, therefore, affected by:

  - An information disclosure vulnerability exists in OpenSSL. A     remote attacker may be able to obtain sensitive information,     caused by the failure to immediately close the TCP connection     after the hosts encounter a zero-length record with valid padding.
    (CVE-2019-1559)

  - A denial of service (DoS) vulnerability exists in the moment     module before 2.19.3 for Node.js. An unauthenticated, remote     attacker can exploit this issue, via regular expression of crafted     date string different than CVE-2016-4055 to cause the     CPU consumption. (CVE-2017-18214)

  - A denial of service (DoS) vulnerability exists in the duration     function in the moment package before 2.11.2 for Node.js. An     unauthenticated, remote attackers can exploit this issue,     via date string ReDoS which will cause CPU consumption.
    (CVE-2016-4055)

According to its self-reported version number, Moment.js is prior to 2.11.2. Therefore, it may be affected by a regular expression denial of service vulnerability when arbitrary user input is passed into moment.duration().

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

According to its self-reported version number, the Oracle Primavera Unifier installation running on the remote web server is 16.x prior to 16.2.15.0, 17.x prior to 17.12.7.0, or 18.x prior to 18.7.0.0. It is, therefore, affected by multiple vulnerabilities.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
