CVE-2024-11122Public exploitNetwork attack vector

Authenticated arbitrary file upload via unchecked file parameter

Published Nov 12, 2024 · Updated Nov 12, 2024

Unrestricted file upload in Lingdang CRM 8.6.4.0 through 8.6.4.3 allows remote authenticated users to upload files via file. The upload operation in /crm/wechatSession/index.php accepts the file parameter without restricting dangerous file types. A low-privileged account is required; successful exploitation places attacker-chosen content on the CRM server, while server-side execution is not established.
