The Java software platform provides a number of features designed for improving the security of Java applications. This includes enforcing runtime constraints through the use of the Java Virtual Machine (JVM), a security manager that sandboxes untrusted code from the rest of the operating system, and a suite of security APIs that Java developers can utilise.

An example of how you can see code injection first-hand is to use your browser's developer tools. Code injection vulnerabilities are recorded by the National Institute of Standards and Technology (NIST) in the National Vulnerability Database as CWE-94. Code injection peaked in 2008 at 5.66% as a percentage of all recorded vulnerabilities. [4]
This type of vulnerability would be bad enough if it was limited to just one product or brand. But because Log4j is such a ubiquitous technology, the effect of this will be exponentially higher.

Exploits are not to be confused with vulnerabilities. An Exploit is an automated or manual attack that utilises the vulnerability. It is not a listing of a vulnerability found in a particular product for example. Follow-On Attacks; Follow-on attacks are any other attacks that may be enabled by this particular attack pattern.
