Name of the Vulnerable Software and Affected Versions Flamingo (aka FlamingoIM) through 2020-09-29

Description The issue allows for ../ directory traversal. This is possible because the only unpredictable part of a file-transfer request, an MD5 computation, occurs on the client side. Since the product's source code is available, the computation details can be easily determined, enabling the traversal.

Recommendations For Flamingo (aka FlamingoIM) through 2020-09-29, consider restricting file-transfer requests until a patch is available. As a temporary workaround, avoid using the MD5 computation for file-transfer requests. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
