How to Fix CVE-2021-41251

To remediate this vulnerability, upgrade all affected @sap cloud sdk/core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@sap-cloud-sdk/core fixed: 1.52.0 
npm install @sap-cloud-sdk/core@1.52.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @sap-cloud-sdk/core

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2021-41251, inspect your project dependencies using npm:

npm ls @sap-cloud-sdk/core

Analyze the terminal output to locate any version of @sap cloud sdk/core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.52.0), your application is affected.

Note: The npm ls @sap-cloud-sdk/core command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In @sap cloud sdk/core, 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 This affects applications on SAP Business Technology Platform that use the SAP Cloud SDK and enabled caching of destinations. In some cases, when user information was missing, destinations were cached without user information, allowing other users to retrieve the same destination with its permissions. By default, destination caching is disabled. If it is enabled the maximum lifetime is 5 minutes which limits the attack vector. ### Patches The problem was fixed by #1769 and #1770. The security for caching has been increased. The changes are released in version 1.52.0. ### Workarounds Disable destination caching (it is disabled by default). ### References [destination cache API docs](https://sap.github.io/cloud-sdk/api/1.51.0/modules/sap_cloud_sdk_core#destinationCache) ### For more information If you have any questions or comments about this advisory: * Open an issue in https://github.com/SAP/cloud-sdk-js
