According to its banner, the version of OpenSSL on the remote host is version 1.1.0 prior to 1.1.0d and is affected by multiple vulnerabilities :

  • A NULL pointer dereference flaw exists in ‘ssl/statem/statem_clnt.c’ that is triggered during the handling of parameters for the DHE or ECDHE key exchanges. This may allow a remote attacker to crash a process linked against the library. (CVE-2017-3730)
  • An out-of-bounds read flaw exists in ‘crypto/evp/e_chacha20_poly1305.c’ that is triggered during the handling of packets when using the CHACHA20/POLY1305 cipher. This may allow a remote attacker to crash a process linked against the library. (CVE-2017-3731)
  • A carry propagating flaw exists in the Montgomery squaring procedure in ‘crypto/bn/asm/x86_64-mont5.pl’. This may cause ‘BN_mod_exp’ to produce incorrect results, which may potentially allow an attacker to derive information regarding private keys. (CVE-2017-3732)
