Name of the Vulnerable Software and Affected Versions Facebook Thrift versions prior to 2019.05.06.00

Description The issue arises when Legacy C++ Facebook Thrift servers, using cpp instead of cpp2, fail to error upon receiving messages containing containers of fields of unknown type. This allows malicious clients to send short messages that take a long time for the server to parse, potentially leading to denial of service.

Recommendations For Facebook Thrift versions prior to 2019.05.06.00, update to version 2019.05.06.00 or later to resolve the issue. As a temporary workaround, consider restricting access to the server to minimize the risk of exploitation.
