CAPEC-67: String Format Overflow in syslog()
Description
Extended Description
This attack first requires the adversary to trick the victim into installing a Trojan Horse application on their system, such as a malicious web browser plugin, which the adversary then leverages to mount the attack. The victim interacts with a web application, such as a banking website, in a normal manner and under the assumption that the connection is secure. However, the adversary can now alter and/or reroute traffic between the client application (e.g., web browser) and the coinciding endpoint, while simultaneously displaying intended transactions and data back to the user. The adversary may also be able to glean cookies, HTTP sessions, and SSL client certificates, which can be used to pivot into an authenticated intranet. Identifying AITB is often difficult because these attacks are successful even when security mechanisms such as SSL/PKI and multifactor authentication are present, since they still function as intended during the attack.
