**Name of the Vulnerable Software and Affected Versions**
Kiteworks Totemomail versions 7.x through 8.2.1
**Description**
The issue allows for directory traversal, enabling unauthenticated file read and delete operations, as well as write operations, through the `/responsiveUI/EnvelopeOpenServlet` endpoint, specifically with the `messageId` parameter, and the `displayLoginChunkedImages` and `storeLoginChunkedImages` variables.
**Recommendations**
For Kiteworks Totemomail versions 7.x through 8.2.1, update to version 8.3.0 or later to resolve the issue.
As a temporary workaround, consider restricting access to the `/responsiveUI/EnvelopeOpenServlet` endpoint until a patch is available.
Avoid using the `messageId` parameter in the affected endpoint until the issue is resolved.
Restrict the use of `displayLoginChunkedImages` and `storeLoginChunkedImages` variables to minimize the risk of exploitation.
