false positives are present when the values are set to 1 for utf and lookup. it's possible to raise this to ttp (direct finding) if removal of other_lookups occur and score is raised to 2 (down from 4).	t1133 t1190 t1505.003 web server splunk
false positives may be present with legitimate applications. attempt to filter by dest ip or use asset groups to restrict to servers.	t1133 t1190 t1505.003 web server splunk

limited false positives should occur as this pattern is highly specific to cve-2025-24813 exploitation. however, legitimate application errors that use similar cookie patterns and result in 500 status codes might trigger false positives. review the jsessionid cookie format and the associated request context to confirm exploitation attempts.	t1190 t1505.003 web application splunk
particular web applications may spawn a shell process legitimately	t1190 t1505 t1505.003 windows sigma
some legitimate applications might use put requests to create .session files, especially in custom implementations that leverage tomcat's session persistence mechanism. verify if the detected activity is part of a normal application flow or if it correlates with other suspicious behavior, such as subsequent get requests with manipulated jsessionid cookies.	t1190 t1505.003 web application splunk

the query is structured in a way that `action` (read, create) is not defined. review the results of this query, filter, and tune as necessary. it may be necessary to generate this query specific to your endpoint product.	t1133 t1190 t1505.003 t1566.001 endpoint splunk
there might be false positives associted with this detection since items like args as a web argument is pretty generic.	t1133 t1505.003 web server splunk
