Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

| 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.
