Name of the Vulnerable Software and Affected Versions Weaver E-Office version 9.5

Description The issue is related to the absence of restrictions on file uploads in the App/Ajax/ajax.php?action=mobile upload save component of the Weaver E-Office platform. This allows a remote attacker to upload arbitrary files, potentially impacting the confidentiality, integrity, and availability of protected information. The manipulation of the upload quwan argument leads to unrestricted upload. The attack can be launched remotely.

Recommendations For Weaver E-Office version 9.5, as a temporary workaround, consider restricting access to the "App/Ajax/ajax.php?action=mobile upload save" endpoint to minimize the risk of exploitation. Avoid using the upload quwan argument in the affected endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
