SAP NetWeaver AS Java CVE-2019-0391 Information Disclosure Vulnerability


### Description SAP NetWeaver AS Java is prone to an information-disclosure vulnerability. Attackers can exploit this issue to obtain sensitive information that may aid in launching further attacks. SAP NetWeaver AS Java versions 7.10, 7.20, 7.30, 7.31, 7.4 and 7.5 are vulnerable. ### Technologies Affected * SAP NetWeaver AS Java 7.10 * SAP NetWeaver AS Java 7.20 * SAP NetWeaver AS Java 7.30 * SAP NetWeaver AS Java 7.31 * SAP NetWeaver AS Java 7.4 * SAP NetWeaver AS Java 7.5 ### Recommendations **Block external access at the network boundary, unless external parties require service.** If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of successful exploits. **Run all software as a nonprivileged user with minimal access rights.** To reduce the impact of latent vulnerabilities, run all applications with the minimal amount of privileges required for functionality. **Deploy network intrusion detection systems to monitor network traffic for malicious activity.** Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include suspicious URI sequences. Updates are available. Please see the references or vendor advisory for more information.
