Issue
- Liferay does not restrict a URL that has a 'sleepy user agent' query appended to it like:
https://domain/page?1%2b(select*from(select(sleep(x)))a)%2b=1
Resolution
- Sleepy user agent payload gets a page in sleep mode(inactive) for x seconds of time, which is not the observed behavior on the Liferay portal.
- There would be the addition of an SQL query in the User-agent header of the page, which is also False in this case.
- Hence, this vulnerability is not present on Liferay.
