SAP NetWeaver Application Server for Java is affected by a log injection vulnerability. SAP NetWeaver AS for Java - versions ENGINEAPI 7.50, SERVERCORE 7.50, J2EE-APPS 7.50, allows an unauthenticated attacker to craft a request over the network which can result in unwarranted modifications to a system log without user interaction. There is no ability to view any information or any effect on availability.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
