- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-10-13 · Updated: 2026-10-13

## Affected

- SAP\_SE SAP NetWeaver and SAP Web Dispatcher (Internet Communication Manager): HDB 2.00, KRNL64UC 7.53, WEBDISP 7.53, 7.54, 7.77, 7.93, 9.16, XS\_ADVANCED\_RUNTIME 1.00, SAP\_EXTENDED\_APP\_SERVICES 1, CONTSERV 7.53, KERNEL 7.53, 9.18, 9.19, 9.20

## Description

SAP NetWeaver and SAP Web Dispatcher do not properly validate certain fields in specially crafted requests handled by an internal protocol component. An unauthenticated attacker could send a malicious request that triggers a memory-handling error, causing the affected process to crash. Successful exploitation can therefore result in a high impact on the availability of the affected application. There is no impact on the confidentiality or integrity of the application.
