Plain English Summary

AI-powered analysis for quick understanding

This vulnerability allows an attacker to send specially crafted requests to an SAP Web Dispatcher, which can trick the connected back-end server into executing harmful commands. The attacker does not need to be authenticated, but they may need to send multiple requests to successfully exploit the issue.

Technical Description

SAP Web Dispatcher versions - 7.49, 7.53, 7.77, 7.81, KRNL64NUC - 7.22, 7.22EXT, 7.49, KRNL64UC -7.22, 7.22EXT, 7.49, 7.53, KERNEL - 7.22, 7.49, 7.53, 7.77, 7.81, 7.83 processes allow an unauthenticated attacker to submit a malicious crafted request over a network to a front-end server which may, over several attempts, result in a back-end server confusing the boundaries of malicious and legitimate messages. This can result in the back-end server executing a malicious payload which can be used to read or modify any information on the server or consume server resources making it temporarily unavailable.
