Log4j is a Java-based logging utility. It is not typically exploited directly, but rather, it can be used by an attacker to gain access to sensitive information or to execute malicious code. Here are some ways in which log4j might be exploited: Information leakage: An attacker might be able to access sensitive information by reading log files that are generated by log4j. For example, if log4j is configured to log database queries and the queries include sensitive data, an attacker could potentially access that data through the log files. Code injection: If an attacker is able to modify the logging configuration for log4j, they might be able to execute arbitrary code by injecting it into the logging statements. For example, an attacker might be able to inject malicious Java code into a log message that is then executed when the log message is processed by log4j. Denial of service: An attacker might be able to cause a denial of service (DoS) attack by causing log4j to generate a la...
