CVE-2017-16691 — Sap Business Application Software Integrated Solution security vulnerability
SAP Note Assistant tool (SAP BASIS from 7.00 to 7.02, from 7.10 to 7.11, 7.30, 7.31,7.40, from 7.50 to 7.52) supports upload of digitally signed note file of type 'SAR'. The digital signature verification is done together with the extraction of note file contained in the SAR archive. It is possible to append a tampered file to the SAR archive using SAPCAR tool and during the extraction, digital signature verification fails but the tampered file is extracted.

Matched remediation archetype
Cryptography, certificate, signature, and channel validation
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Inventory affected algorithms, key uses, trust stores, certificate validation settings, random sources, and plaintext channels across clients and services.
- Determine which secrets, identities, signatures, or data protections depend on the affected primitive or validation path.
- Check debug, compatibility, fallback, and hostname or audience override settings in build and runtime configuration.
Remediate safely
- Use a maintained platform cryptographic API with approved algorithms, modes, parameters, randomness, and full peer identity validation.
- Remove insecure fallback and validation bypasses; separate keys by purpose and load them from managed secret storage.
- Plan rotation or reissuance for affected keys, certificates, tokens, hashes, or ciphertext and document compatibility sequencing.
