This detection rule targets web access logs to identify possible Java payloads that could indicate an attempted exploitation of vulnerabilities in web applications. Specifically, it looks for specific patterns in the requests that align with known Java injection techniques, particularly focusing on those that could exploit vulnerabilities in applications such as Confluence. The rule uses keywords that are characteristic of Java code execution attempts, leveraging specific strings that are likely to be used in malicious payloads. This includes sections of code typical for dynamic execution, such as the use of `getRuntime().exec()` and variable referencing through `${}` syntax, which may indicate attempts at remote code execution (RCE). By monitoring access logs for these patterns, security teams can better protect their environments from threats that seek to gain unauthorized access or control over systems through Java-based exploits.
