Description

Due to a Memory Corruption vulnerability in Application Server ABAP for SAP NetWeaver and ABAP Platform, an unauthenticated attacker could send specially crafted requests to the application. If processed by the application, these requests could trigger a memory corruption condition in the parsing routine, which could cause the affected processes to crash and restart. By repeatedly sending such requests, the attacker could cause a sustained denial of service, leading to a high impact on availability. Confidentiality and integrity remain unaffected.

Detection & mitigation playbook

Vulnerability

  1. Detect

    Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

  2. Remediation status

    The records we use list no fixed release for CVE-2026-76970. Check the upstream advisory for a patched version, and apply the exposure-reduction steps below in the meantime.

  3. Mitigate without a patch

    Stop feeding it untrusted input: reject or quarantine files and payloads from unverified sources until you can upgrade, restrict accepted formats to the ones you actually need, and run the parsing or decoding step in a least-privileged sandbox or short-lived worker so a crash or corrupted read cannot reach the rest of the process.
