According to SAP Security Advisory team a workaround exists. It is advisable to implement the correction as monthly patch process.
Missing authority checks are still the most common security defect related to authorizations in custom code. Since SAP uses an explicit authorization model, an authority checks must be coded in order to be executed. If an explicit check is not coded, all users have access. This type of vulnerability not only exists in SAP standard it also exists in customer coding. Check your custom developments for vulnerabilities that pose a risk to your systems. SecurityBridge helps detect code vulnerabilities before they are implemented in production.
Risk specificationThis note has been re-released with minor textual changes in the 'Other Terms' section. SAP NetWeaver allows unauthenticated attacker to inject code that may expose sensitive data due to insufficient encoding of user data.
The URL parameters are now properly encoded to prevent a successful XSS attack. Alternativly, the consulting team has proposed the following: "Cross-site scripting/request forgery filter engine on IDS/IPS/firewall systems. ". The suggestion may be considered, as a workaround or compensating mitigation. We recommend installing/applying the correction wherever possible and as soon as possible. Base your decision on whether or not to apply the patch on your companies and systems risk perspective and consider the provided CVSS 4.7 score.
