Summary

The administrative console in IBM WebSphere Application Server (WAS) 8.0.0 before 8.0.0.11 and 8.5 before 8.5.5.6, when the Security feature is disabled, allows remote authenticated users to hijack sessions via the JSESSIONID parameter.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Embedding Scripts within Scripts
    An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute scripts. The attacker leverages this capability to execute scripts to execute his/her own script by embedding it within other scripts that the target software is likely to execute. The attacker must have the ability to inject script into script that is likely to be executed. If this is done, then the attacker can potentially launch a variety of probes and attacks against the web server's local environment, in many cases the so-called DMZ, back end resources the web server can communicate with, and other hosts. With the proliferation of intermediaries, such as Web App Firewalls, network devices, and even printers having JVMs and Web servers, there are many locales where an attacker can inject malicious scripts. Since this attack pattern defines scripts within scripts, there are likely privileges to execute said attack on the host. Of course, these attacks are not solely limited to the server side, client side scripts like Ajax and client side JavaScript can contain malicious scripts as well. In general all that is required is for there to be sufficient privileges to execute a script, but not protected against writing.
  • Signature Spoofing by Key Theft
    An attacker obtains an authoritative or reputable signer's private signature key by theft and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

descriptionThe 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

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

    cipher suites which can be factored in a short amount of

  - 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)");
