A note with CVSS 7.1 for component GRC-SAC-EAM was released by SAP on 13.09.2022. The correction/advisory 3237075 was described with "[CVE-2022-39801] Insufficient Firefighter Session Expiration in SAP GRC Access Control Emergency Access Management" and affects the system type ABAP.
A workaround does not exist, according to SAP Security Advisory team. It is advisable to implement the correction as part of maintenance.
The vulnerability addressed is missing security function within ABAP.
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 specificationSAP GRC Access control Emergency Access Management allows an authenticated attacker to access a Firefighter session even after it is closed in Firefighter Logon Pad but only within the firewall.
The Applications have been updated to check SM04 and SM05.
