Advisory

SAP takes the security of its vast product portfolio very seriously and thus releases security fixes for vulnerabilities reported by external researchers and their customers every second Tuesday of the month.

SAP Note 2486446 was released on 14.07.2020 and deals with "Missing Authorization check in Pricat Inbound and Pricat Outbound" within ABAP. We advice you to follow the instructions, to resolve missing authorization check with a medium potential for exploitation in component IS-R-BD-PCT-IN.

According to SAP Security Advisory team a workaround does not exist. 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 specification

Pricat Inbound and Pricat Outbound does not perform necessary authorization checks for an authenticated user, resulting in escalation of privileges.

Solution

Pricat Inbound and Pricat Outbound have been extended to properly enforce the authorization checks.

Disclaimer

ABEX takes the security of SAP products very seriously. We very much encourage the responsible disclosure of security vulnerabilities. If you have detected a vulnerability in one of the SAP software products – either in the latest or in a former product version follow the guidelines and processes in accordance with the SAP portal page “Report a Security Vulnerability to SAP”.

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.

Secure code
Customer created code contains security risks. Use modern technologies to detect coding flaws mitigate unneccessary risks. Start to detect:

  • Open & Native SQL Injection
  • Potential backdoors
  • Insuffient authorization checks of user administration bypassed
  • Injections of operating system commands
  • and many more..
