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.

| description | According to its self-reported version, the IBM WebSphere MQ server installed on the remote Windows host is version 7.0.1.x without patch APAR IT14385, 7.1.0.x prior to 7.1.0.9, 7.5.0.x prior to 7.5.0.8, 8.0.0.x prior to 8.0.0.6, or 9.0.0.x prior to 9.0.0.1. It is, therefore, affected by multiple vulnerabilities : - A flaw exists in the Java Message Service (JMS) in the JMSObjectMessage class due to improper sanitization of input when deserializing Java objects. An authenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2016-0360) - A flaw exists due to improper data conversion handling that allows an authenticated, remote attacker to crash the MQ channel. (CVE-2016-3013) - A flaw exists that under nonstandard configurations causes password data to be sent in cleartext over the network. A man-in-the-middle attacker can exploit this to disclose passwords. (CVE-2016-3052) - An unspecified flaw exists that allows an authenticated, remote attacker, who has access to the queue manager and queue, to cause a denial of service to other channels running under the same process. (CVE-2016-8915) - A flaw exists that allows an unauthenticated, remote attacker to have an unspecified impact. No other details are available. (CVE-2016-8971) - An unspecified flaw exists that allows an authenticated, remote attacker, who has access to the queue manager, to disrupt MQ channels using specially crafted HTTP requests, resulting in a denial of service condition. (CVE-2016-8986) - An unspecified flaw exists that allows an authenticated, remote attacker, who has authority to create cluster objects, to cause a denial of service condition in MQ clustering.
