CVE-2023-42479Network attack vector

Information disclosure and modification via framed XSS

Published Dec 12, 2023 · Updated Nov 26, 2024

Cross-site scripting in SAP Biller Direct 635 and 750 allows remote attackers to alter or disclose non-sensitive information through a framed URL. A hidden frame loads a crafted Biller Direct URL that submits a cross-site-scripting request; SAP has not disclosed the affected parameter or code locus. Exploitation is unauthenticated but requires a user to load the attacker-supplied frame, and the reported consequence is limited to non-sensitive information.
