Advisory

SAP takes the security of its vast product portfolio very seriously and thus releases security fixes for vulnerabilities reported by external researchers and their customers every second Tuesday of the month.

SAP Note 3765424 was released on 13.10.2026 and deals with "3765424 - [CVE-2026-58249 ] Memory Corruption vulnerability in SAP NetWeaver and SAP Web Dispatcher (Internet Communication Manager)" within Kernel, HANA platform, Web Dispatcher. We advice you to follow the instructions, to resolve memory corruption with a high potential for exploitation in component BC-CST-IC.

According to SAP Security Advisory team a workaround exists. It is advisable to implement the correction as monthly patch process.

Risk specification

SAP NetWeaver and SAP Web Dispatcher allow an unauthenticated attacker to send a specially crafted request to an internal protocol component, triggering a memory-handling error that causes the affected process to crash and renders the application unavailable.

Solution

The affected protocol component now correctly validates the relevant request fields, preventing the memory-handling error that previously caused the process to crash.
Alternativly, the consulting team has proposed the following: "Disable HTTP/2 support by setting the profile parameter `icm/HTTP/support_http2` to `FALSE`. Disabling HTTP/2 does not affect functionality but may reduce browser UI performance. Refer to the Workaround section for more information.". The suggestion may be considered, as a workaround or compensating mitigation. We recommend installing/applying the correction wherever possible and as soon as possible. Base your decision on whether or not to apply the patch on your companies and systems risk perspective and consider the provided CVSS 7.5 score.
