## Technical details

An unrestricted file upload vulnerability (CWE-434) exists in Metasoft MetaCRM 6.4.0 within the 'develop/systparam/softlogo/upload.jsp' file. The application fails to properly validate file types or extensions during the upload process. A remote attacker with low-level privileges can exploit this by sending a specially crafted request to upload a malicious file (such as a JSP web shell).
