Weaver E-cology 8.0 SQL Injection File Read via SignatureDownLoad

Published Aug 11, 2026 · corrected/updated Aug 11, 2026 · Weaver Network Co., Ltd. E-cology 8.0 · evidence confidence very high

Weaver (Fanwei) E-cology 8.0 contains a SQL injection vulnerability in the SignatureDownLoad servlet that allows unauthenticated remote attackers to read arbitrary files by injecting a UNION SELECT payload into the markId GET parameter, which is concatenated unsanitized into a SQL query. Attackers can control the markPath value returned by the query to supply an attacker-controlled filesystem path, causing the servlet to read and stream back arbitrary files accessible to the application server process, including sensitive configuration files containing database credentials.
