Security readout for executives and security teams
CVE-2021-31537 is a cross-site scripting issue in SIS SIS-REWE Go versions before 7.7 SP17. If the affected web pages are reachable, an attacker may be able to make a user’s browser execute unwanted script in the application context. The source bundle does not provide CVSS scoring or confirmed exploitation. Exposure is most likely where SIS-REWE Go before 7.7 SP17 is deployed and its REWE Go web interface is reachable by users, partners, or the internet. The provided affected-product metadata is sparse, so confirm actual product ownership and version locally. Treat this as a moderate-priority web application risk unless the interface is internet-facing or used with privileged sessions, in which case prioritize faster remediation. The main business concern is browser-side compromise through trusted application pages. Mitigation focus: Upgrade SIS-REWE Go to 7.7 SP17 or later where supported.; Check SIS Informatik and SEC Consult guidance before applying production changes.; Restrict access to the REWE Go web interface to trusted networks..
