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 7.0.0.43, 8.0 prior to 8.0.0.13, 8.5 prior to 8.5.5.11, or 9.0 prior to 9.0.0.2. It is, therefore, affected by multiple vulnerabilities : - A remote code execution vulnerability exists due to improper sanitization user-supplied input when deserializing Java objects. An authenticated, remote attacker can exploit this, via a crafted serialized object, to execute arbitrary Java code. (CVE-2016-5983) - An information disclosure vulnerability exists due to improper handling of responses. An unauthenticated, remote attacker can exploit this to disclose sensitive server identification information. (CVE-2016-5986)
