System crashes and information disclosure via memory-management errors
Published Jul 11, 2023 · Updated Oct 23, 2024
Memory corruption in SAP Web Dispatcher allows remote attackers to disclose information or crash systems through unauthenticated requests. Logical errors in the dispatcher's memory management permit an out-of-bounds write while processing untrusted network input. SAP has not publicly identified the affected request path or function; successful exploitation can corrupt memory, expose limited information, or terminate the service.
