Description

SAP NetWeaver does not perform necessary authorization checks and lacks sufficient input validation in certain remote-enabled functionality. An attacker with low privileges could send specially crafted input through a remote interface to inject and execute arbitrary code within the affected system. Successful exploitation could extend the attacker's reach beyond the vulnerable component, resulting in a high impact on confidentiality, integrity and availability.

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-2026-109795. Check the upstream advisory for a patched version, and apply the exposure-reduction steps below in the meantime.

  3. Mitigate without a patch

    Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
