Multiple vulnerabilities have been reported in SAP NetWeaver, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerabilities are caused due to boundary errors in msg_server.exe when handling packages with opcode 0x43 and sub-opcode 0x4 and can be exploited to cause stack-based buffer overflows via an overly long parameter name or parameter value string in the package sent to TCP port 3900.
Successful exploitation may allow execution of arbitrary code.
Solution: Apply updates. Please contact the vendor for more information.
