Advisory

On 09.06.2020 a security relevant correction has been released by SAP SE. The manufacturer resolves an issue within SAP Success Factors.

SAP Note 2933282 addresses "[CVE-2020-6279] Missing Authorization Check in SAP SuccessFactors Recruiting" to prevent missing authorization check with a high risk for exploitation.

A workaround does not exist, according to SAP Security Advisory team. It is advisable to implement the correction as project, the team suggests.

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 specification

SAP SuccessFactors Recruiting(OData APIs and JobApplicationInterview and JobApplication export permissions) does not perform necessary authorization checks for an authenticated user, resulting in escalation of privileges.

Solution

Read/Write permissions for field and row level controls are added to the JobApplicationInterview in SuccessFactors Recruitment Management, 2005 release. Consequently Resumes have now exposed JobApplicationInterview entity with row and field level permissions. Users with read/write permissions are only allowed to view the Resumes.

The advisory is valid for

  • SFSF_RECRUITING_MGMT 2005

The advisories found within the ABEX security advisory are generated and continuously enriched by ABEX and affiliated security consultants, partners, customers of the SecurityBridge security suite, SAP support, and advisory groups.

There is no disclosure of zero-day vulnerabilities. In such case, the platform only provides details on which version or signature updates are available within the SecurityBridge platform in order to monitor or measure the vulnerability

In accordance with SAP guidelines, ABEX only discloses issues where the fixing security note has been released at least three months ago. The vulnerability platform makes no references to available exploits or Proof of Concepts (PoC). Advisories and vulnerabilities will always mention the fixing security note or hints to the corresponding SAP documentation.
