"The IBM WebSphere Application Server running on the remote host is
version 7.0 prior to 7.0.0.39, 8.0 prior to 8.0.0.11, or 8.5 prior to
8.5.5.6. It is, therefore, potentially affected by multiple
vulnerabilities :

  - A security feature bypass vulnerability, known as FREAK
    (Factoring attack on RSA-EXPORT Keys), exists in the IBM
    Global Security Kit (GSKit) due to the support of weak
    EXPORT_RSA cipher suites with keys less than or equal to
    512 bits. A man-in-the-middle attacker may be able to
    downgrade the SSL/TLS connection to use EXPORT_RSA
    cipher suites which can be factored in a short amount of
    time, allowing the attacker to intercept and decrypt the
    traffic. (CVE-2015-0138)

  - An information disclosure vulnerability exists due to a
    flaw in the Bleichenbacher countermeasure implementation 
    in Apache WSS4J. A remote attacker can exploit this, via
    a crafted message, to determine where an encryption
    failure to place, allowing the attacker to gain access
    to the plaintext symmetric key. (CVE-2015-0226)

  - An XML External Entity (XXE) vulnerability exists due to
    an incorrectly configured XML parser that accepts XML
    external entities from an untrusted source. A remote
    attacker can exploit this, via specially crafted XML
    data, to gain access to arbitrary files. (CVE-2015-0250)

  - A privilege escalation vulnerability exists due to a
    flaw that occurs in 'full' profile and 'liberty' profile
    when using an OAuth grant password. A remote attacker
    can exploit this to gain elevated privileges.
    (CVE-2015-1885)

  - A privilege escalation vulnerability exists due to
    incorrect settings in the serveServletsbyClassname
    functionality. A remote attacker can exploit this to
    gain elevated privileges. (CVE-2015-1927)

  - An information disclosure vulnerability exists that
    allows an unauthenticated, remote attacker to identify
    the proxy server software by reading the HTTP 'Via'
    header. (CVE-2015-1932)

  - An unspecified flaw exists in the administrative console
    that allows a remote attacker, via the 'JSESSIONID'
    parameter, to hijack a user's session. (CVE-2015-1936)

  - A privilege escalation vulnerability exists due to an
    unspecified flaw that occurs when handling user roles.
    A local attacker can exploit this to gain elevated
    privileges. (CVE-2015-1946)
  
  - A security feature bypass vulnerability exists, known as
    Bar Mitzvah, due to improper combination of state data
    with key data by the RC4 cipher algorithm during the
    initialization phase. A man-in-the-middle attacker can
    exploit this, via a brute-force attack using LSB values,
    to decrypt the traffic. (CVE-2015-2808)

  - An unspecified flaw exists that allows an
    unauthenticated, remote attacker to spoof servlets or
    disclose sensitive information. (CVE-2015-4938)");

or 8.5 prior to 8.5.5.7. It is, therefore, potentially affected by
multiple vulnerabilities :

  - An overflow condition exists in the XML_GetBuffer()
    function in xmlparse.c due to improper validation of
    user-supplied input when handling compressed XML
    content. An attacker can exploit this to cause a buffer
    overflow, resulting in the execution of arbitrary code.
    (CVE-2015-1283)

  - A denial of service vulnerability exists when processing
    an ECParameters structure due to an infinite loop that
    occurs when a specified curve is over a malformed binary
    polynomial field. A remote attacker can exploit this to
    perform a denial of service against any system that
    processes public keys, certificate requests, or
    certificates. This includes TLS clients and TLS servers
    with client authentication enabled. (CVE-2015-1788)

  - An information disclosure vulnerability exists that
    allows an unauthenticated, remote attacker to identify
    the proxy server software by reading the HTTP 'Via'
    header. (CVE-2015-1932)

  - A flaw exists in the chunked transfer coding
    implementation due to a failure to properly parse chunk
    headers. A remote attacker can exploit this to conduct
    HTTP request smuggling attacks. (CVE-2015-3183)

  - An unspecified flaw exists that allows an
    unauthenticated, remote attacker to spoof servlets or
    disclose sensitive information. (CVE-2015-4938)

  - An overflow condition exists in the Administration
    Server due to improper validation of user-supplied
    input. An attacker can exploit this, via a specially
    crafted request, to cause a stack-based buffer overflow,
    resulting in a denial of service condition or the
    execution of arbitrary code. (CVE-2015-4947)
