Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-269: Improper Privilege Management, where the product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. In Github.com/sap/cloud security client go, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact SAP BTP Security Services Integration Library ([Golang] github.com/sap/cloud-security-client-go) allows under certain conditions an escalation of privileges. On successful exploitation, an unauthenticated attacker can obtain arbitrary permissions within the application. ### Patches Upgrade to patched version >= 0.17.0 We always recommend to upgrade to the latest released version. ### Workarounds No workarounds ### References https://www.cve.org/CVERecord?id=CVE-2023-50424
