The Roundcube project reports

steps/mail/sendmail.inc in Roundcube before 1.1.7 and 1.2.x before 1.2.3, when no SMTP server is configured and the sendmail program is enabled, does not properly restrict the use of custom envelope-from addresses on the sendmail command line, which allows remote authenticated users to execute arbitrary code via a modified HTTP request that sends a crafted e-mail message.

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8132-1 advisory.

    It was discovered that Roundcube Webmail did not properly sanitize

    certain HTML elements within the e-mail body. An attacker could possibly

    use this issue to cause a cross-site scripting attack. This issue was only

    addressed in Ubuntu 16.04 LTS. (CVE-2016-4068, CVE-2016-4069)

    It was discovered that Roundcube Webmail did not properly handle certain

    configuration parameters. An attacker could possibly use this issue to

    execute arbitrary code. This issue was only addressed in Ubuntu 16.04 LTS.

    (CVE-2016-9920)

    It was discovered that Roundcube Webmail did not properly sanitize CSS styles

    within SVG documents. An attacker could possibly use this issue to cause

    a cross-site scripting attack. This issue was only addressed in Ubuntu 16.04 LTS. (CVE-2017-6820)

    It was discovered that Roundcube Webmail did not properly restrict exec call in

    certain drivers of the password plugin. An authenticated user could possibly

    use this issue to perform arbitrary password resets. This issue was only addressed in

    Ubuntu 16.04 LTS. (CVE-2017-8114)

    It was discovered that Roundcube Webmail did not properly set file permissions within

    the Enigma plugin. An attacker could possibly use this issue to exfiltrate GPG private

    keys via network connectivity. (CVE-2018-1000071)

    It was discovered that Roundcube Webmail did not properly handle GnuPG MDC

    integrity-protection warnings. An attacker could possibly use this issue to obtain

    sensitive information from encrypted communications. (CVE-2018-19205)

    It was discovered that Roundcube Webmail did not properly sanitize <svg> and <style> tags within HTML     attachments. An attacker could possibly use this issue to cause a

    cross-site scripting attack. (CVE-2018-19206)

    It was discovered that Roundcube Webmail did not properly handle partially encrypted multipart messages.
    An attacker could possibly use this issue to cause

    leaking of the plaintext of encrypted messages via an email reply. (CVE-2019-10740)

    It was discovered that Roundcube Webmail did not properly sanitize a certain parameter

    within the archive plugin. An attacker could possibly use this issue to perform an

    IMAP injection attack. This issue was only addressed in Ubuntu 16.04 LTS. (CVE-2018-9846)

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

The remote host is affected by the vulnerability described in GLSA-201612-44 (Roundcube: Arbitrary code execution)

    Roundcube, when no SMTP server is configured and the sendmail program is       enabled, does not properly restrict the use of custom envelope-from       addresses on the sendmail command line.
  Impact :

    An authenticated remote attacker could possibly execute arbitrary code       with the privileges of the process, or cause a Denial of Service       condition.
  Workaround :

    Don&rsquo;t use a MTA (Mail Transfer Agent) in conjunction with Roundcube       which implements sendmail&rsquo;s &ldquo;-O&rdquo; or &ldquo;-X&rdquo; parameter, or       configure Roundcube to use a SMTP server as recommended by upstream.
