Second Order Code Injection Attacks
------------------------------------------------------------------------
SUMMARY
Presented below is an abstract for a whitepaper exploring the
possibilities in second order code injection attacks and their
applications.
DETAILS
Abstract
"Many forms of code injection targeted at web-based applications (for
instance cross-site scripting and SQL injection) rely upon the
instantaneous execution of the embedded code to carry out the attack (e.g.
stealing a user's current session information or executing a modified SQL
query). In some cases it may be possible for an attacker to inject their
malicious code into a data storage area that may be executed at a later
date or time. Depending upon the nature of the application and the way the
malicious data is stored or rendered, the attacker may be able to conduct
a second-order code injection attack.
A second-order code injection attack can be classified as the process in
which malicious code is injected into a web-based application and not
immediately executed, but instead is stored by the application (e.g.
temporarily cached, logged, stored in a database) and then later
retrieved, rendered and executed by the victim."
