Script execution via weak output encoding
Published Sep 10, 2024 · Updated Sep 10, 2024
Reflected XSS in SAP S/4HANA eProcurement releases SAP_APPL 606, 617, 618 and S4CORE 102 through 108 allows remote attackers to run scripts. The eProcurement response applies weak encoding to user-controlled input, allowing that input to become executable browser script when reflected into an application page. No authentication is required, but a user must open the crafted request; the script can read or alter data available in that user's application context without interrupting service.
