Weaver E-cology contains an unauthenticated SQL injection vulnerability that allows remote attackers to execute arbitrary SQL queries by submitting malicious input through the userIdentifiers GET parameter in the mobile plugin endpoint. Attackers can bypass space-based filter controls by wrapping SQL keywords in parentheses to perform UNION-based injection and extract sensitive data including administrator credential hashes from the database. Exploitation evidence was first observed by the Shadowserver Foundation on 2022-07-28.
