Improper Verification of Cryptographic Signature in SAP NetWeaver Application Server ABAP and ABAP Platform
CVE-2026-44748 affects SAP NetWeaver Application Server ABAP and ABAP Platform. According to the provided advisory content, an authenticated attacker with normal privileges can obtain a valid signed message and then submit modified signed XML documents to the verifier. The issue results in acceptance of tampered identity information, indicating improper verification of the XML signature or signed message contents during verification. This is consistent with CWE-347 (Improper Verification of Cryptographic Signature). Successful exploitation can allow altered identity assertions or related signed XML data to be treated as valid by the target application.
