The version of IBM BigFix Remote Control running on the remote host is prior to 9.1.3. It is, therefore, affected by the multiple vulnerabilities :

  • Multiple integer overflow conditions exist in the bundled version of OpenSSL in files s3_srvr.c, ssl_sess.c, and t1_lib.c due to improper use of pointer arithmetic for heap-buffer boundary checks. An unauthenticated, remote attacker can exploit this to cause a denial of service. (CVE-2016-2177)

  • An information disclosure vulnerability exists in the bundled version of OpenSSL in the dsa_sign_setup() function in dsa_ossl.c due to a failure to properly ensure the use of constant-time operations. An unauthenticated, remote attacker can exploit this, via a timing side-channel attack, to disclose DSA key information. (CVE-2016-2178)

  • A vulnerability exists, known as SWEET32, in the bundled version of OpenSSL in the 3DES and Blowfish algorithms due to the use of weak 64-bit block ciphers by default.
    A man-in-the-middle attacker who has sufficient resources can exploit this vulnerability, via a ‘birthday’ attack, to detect a collision that leaks the XOR between the fixed secret and a known plaintext, allowing the disclosure of the secret text, such as secure HTTPS cookies, and possibly resulting in the hijacking of an authenticated session. (CVE-2016-2183)

  • An information disclosure vulnerability exists due to the inclusion of sensitive information in error logs. An authenticated, remote attacker can exploit this to disclose information. (CVE-2016-2928)

  • An information disclosure vulnerability exists due to the transmission of information in cleartext. A man-in-the-middle attacker can exploit this to disclose sensitive information. (CVE-2016-2931)

  • An unspecified flaw exists that allows an unauthenticated, remote attacker to inject arbitrary XML content. (CVE-2016-2932)

  • An information disclosure vulnerability exists due to a flaw that allows traversing outside of a restricted path. An authenticated, remote attacker can exploit this, via a specially crafted request, to disclose arbitrary files. (CVE-2016-2933)

  • A cross-site scripting (XSS) vulnerability exists due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user’s browser session. (CVE-2016-2934)

  • An unspecified flaw exists that allows an unauthenticated, remote attacker to submit invalid HTTP requests, resulting in a denial of service condition for the broker application. (CVE-2016-2935)

  • An information disclosure vulnerability exists due to the storage of information in log files in plaintext. A local attacker can exploit this to disclose sensitive information. (CVE-2016-2943)

  • A flaw exists in the bundled version of OpenSSL in the ssl_parse_clienthello_tlsext() function in t1_lib.c due to improper handling of overly large OCSP Status Request extensions from clients. An unauthenticated, remote attacker can exploit this, via large OCSP Status Request extensions, to exhaust memory resources, resulting in a denial of service condition. (CVE-2016-6304)

  • An out-of-bounds read error exists the bundled version of OpenSSL in the certificate parser that allows an unauthenticated, remote attacker to cause a denial of service via crafted certificate operations.
    (CVE-2016-6306)

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