| Command Execution | If mysqld (<5.0) is running as root AND you compromise a DBA account you can execute OS commands by uploading a shared object file into /usr/lib (or similar). The .so file should contain a User Defined Function (UDF). raptor_udf.c explains exactly how you go about this. Remember to compile for the target architecture which may or may not be the same as your attack platform. |
