The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3571-1 advisory.

    It was discovered that the Erlang FTP module incorrectly handled certain CRLF sequences. A remote attacker     could possibly use this issue to inject arbitrary FTP commands. This issue only affected Ubuntu 14.04 LTS.
    (CVE-2014-1693)

    It was discovered that Erlang incorrectly checked CBC padding bytes. A remote attacker could possibly use     this issue to perform a padding oracle attack and decrypt traffic. This issue only affected Ubuntu 14.04     LTS. (CVE-2015-2774)

    It was discovered that Erlang incorrectly handled certain regular expressions. A remote attacker could     possibly use this issue to cause Erlang to crash, resulting in a denial of service, or execute arbitrary     code. This issue only affected Ubuntu 16.04 LTS. (CVE-2016-10253)

    Hanno Bck, Juraj Somorovsky and Craig Young discovered that the Erlang otp TLS server incorrectly     handled error reporting. A remote attacker could possibly use this issue to perform a variation of the     Bleichenbacher attack and decrypt traffic or sign messages. (CVE-2017-1000385)

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

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2018:0528 advisory.

    Erlang is a general-purpose programming language and runtime environment. Erlang has built-in support for     concurrency, distribution and fault tolerance.

    Security Fix(es):

    * An erlang TLS server configured with cipher suites using RSA key exchange, may be vulnerable to an     Adaptive Chosen Ciphertext attack (AKA Bleichenbacher attack) against RSA. This may result in plain-text     recovery of encrypted messages and/or a man-in-the-middle (MiTM) attack, despite the attacker not having     gained access to the servers private key itself. (CVE-2017-1000385)

The remote host is affected by an information disclosure vulnerability. The SSL/TLS service supports RSA key exchanges, and incorrectly leaks whether or not the RSA key exchange sent by a client was correctly formatted. This information can allow an attacker to decrypt previous SSL/TLS sessions or impersonate the server.

Note that this plugin does not attempt to recover an RSA ciphertext, however it sends a number of correct and malformed RSA ciphertexts as part of an SSL handshake and observes how the server responds.

This plugin attempts to discover the vulnerability in multiple ways, by not completing the handshake and by completing it incorrectly, as well as using a variety of cipher suites. Only the first method that finds the service to be vulnerable is reported.

This plugin requires report paranoia as some services will report as affected even though the issue is not exploitable.

An erlang TLS server configured with cipher suites using RSA key exchange, may be vulnerable to an Adaptive Chosen Ciphertext attack (AKA Bleichenbacher attack) against RSA, which when exploited, may result in plaintext recovery of encrypted messages and/or a Man-in-the-middle (MiTM) attack, despite the attacker not having gained access to the server's private key itself.

For Debian 7 'Wheezy', these problems have been fixed in version 15.b.1-dfsg-4+deb7u2.

We recommend that you upgrade your erlang packages.
