Name of the Vulnerable Software and Affected Versions SAP NetWeaver AS JAVA versions 7.10 through 7.50

Description The issue is related to weaknesses in the authentication procedure of the ENGINEAPI component in the SAP NetWeaver Java Application Server. This can be exploited by a remote attacker to cause a denial of service. The vulnerability allows an attacker to send multiple payloads to a web service without authentication checks, leading to a complete denial of service.

Recommendations For SAP NetWeaver AS JAVA versions 7.10 through 7.50, consider restricting access to the ENGINEAPI component until a patch is available. As a temporary workaround, disabling the web service that allows unauthenticated access may help minimize the risk of exploitation.
