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).","state":0,"publishedAt":"2026-08-11T17:11:18.484+00:00","modifiedAt":"2026-09-30T17:19:46.861+00:00","affected":[{"ecosystem":"Vendor product","name":"E-cology 9.0","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"Weaver Network Co., Ltd.\",\n                    \"product\": \"E-cology 9.0\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"10.53\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"10.54\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"E-cology 8.0","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"Weaver Network Co., Ltd.\",\n                    \"product\": \"E-cology 8.0\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"10.53\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"10.54\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5,"severity":"HIGH"}],"references":["https://www.weaver.com.cn/cs/securityDownload.html#","https://www.weaver.com.cn/cs/ecology_full_log_en.html","https://peiqi.wgpsec.org/wiki/oa/%E6%B3%9B%E5%BE%AEOA/%E6%B3%9B%E5%BE%AEOA%20E-Cology%20HrmCareerApplyPerView.jsp%20SQL%E6%B3%A8%E5%85%A5%E6%BC%8F%E6%B4%9E.html","https://cn-sec.com/archives/1211578.html","https://www.vulncheck.com/advisories/weaver-e-cology-sql-injection-via-hrmcareerapplyperview-jsp"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2022-50997","license":"CVE Program Terms of Use","key":"cve-program:CVE-2022-50997","identifiers":["CVE-2022-50997"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
