CVE-2022-50997: SQL injection vulnerability

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. Attackers can send a single crafted GET request with UNION-based injection payloads through the unsanitized id parameter to retrieve arbitrary data from the Microsoft SQL Server backend. This vulnerability is potentially remediated in software version 10.53 or 10.54. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-18 (UTC).
