Weaver E-cology 8.0 / 9.0 SQL Injection via HrmCareerApplyPerView.jsp
Summary
Weaver (Fanwei) E-cology 8.0 and 9.0 contains a SQL injection vulnerability in the HrmCareerApplyPerView.jsp endpoint that allows unauthenticated remote attackers to extract arbitrary data from the backend database by manipulating the id GET parameter.
