CVE-2022-21234Public exploitNetwork attack vector

Authenticated SQL injection via unsanitized sort order

Published Apr 14, 2022 · Updated Apr 15, 2025

SQL injection in Lansweeper 9.1.20.2 allows remote authenticated users to execute arbitrary SQL via a crafted EchoAssets.aspx request. The LsAgentRepository.GetAssetsByGroupId method concatenates the unsanitized order parameter directly into its ORDER BY clause. An account with proper permissions is required, and the published proof of concept discloses the database version through an error.
