An unauthenticated attacker in SAP Web Dispatcher - versions WEBDISP 7.49, WEBDISP 7.53, WEBDISP 7.54, WEBDISP 7.77, WEBDISP 7.81, WEBDISP 7.85, WEBDISP 7.88, WEBDISP 7.89, WEBDISP 7.90, KERNEL 7.49, KERNEL 7.53, KERNEL 7.54 KERNEL 7.77, KERNEL 7.81, KERNEL 7.85, KERNEL 7.88, KERNEL 7.89, KERNEL 7.90, KRNL64NUC 7.49, KRNL64UC 7.49, KRNL64UC 7.53, HDB 2.00, XS_ADVANCED_RUNTIME 1.00, SAP_EXTENDED_APP_SERVICES 1, can 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 information on the server or make it temporarily unavailable. • https://me.sap.com/notes/3233899 https://www.sap.com/documents/2022/02/fa865ea4-167e-0010-bca6-c68f7e60039b.html • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

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.

Esto puede resultar en que el servidor back-end ejecutar una carga útil maliciosa que puede ser usada para leer o modificar cualquier información en el servidor o consumir recursos del servidor haciéndolo temporalmente no disponible SAP Web Dispatcher suffers from an HTTP request smuggling vulnerability. • http://packetstormsecurity.com/files/166964/SAP-Web-Dispatcher-HTTP-Request-Smuggling.html http://seclists.org/fulldisclosure/2022/May/3 https://launchpad.support.sap.com/#/notes/3080567 https://wiki.scn.sap.com/wiki/pages/viewpage.action?pageId=585106405 • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
