The remote host is running a service that is affected by remote code
execution and information disclosure vulnerabilities.
The Advantech WebAccess software installed on the remote Windows host
includes an RPC service (webvrpcs.exe) that listens remotely on TCP
port 4592. It is affected by two vulnerabilities :
- An overflow condition exists due to improper validation
of user-supplied input. An unauthenticated, remote
attacker can exploit this, via a specially crafted
request, to execute arbitrary code.
- An information disclosure vulnerability exists that
allows an unauthenticated, remote attacker to obtain the
security code value that protects the SCADA node via a
long string in an RPC request to TCP port 4592.
