Esta herramienta permite un análisis rápido de una base de datos SAP para identificar usuarios o roles configurados con permisos peligrosos o combinaciones de permisos. Es similar a Bloodhound para Active Directory.
Puede usar pipx :
$ pipx install git+https://github.com/synacktiv/bissap.git
O, usando pip :
$ git clone https://github.com/synacktiv/bissap
$ python3 -m venv .venv && . .venv/bin/activate # Optional: Install in a venv
$ pip install .
O, si prefiere usar paquetes Debian:
# apt install python3-click python3-colorlog python3-sqlalchemy python3-frozendict python3-rich python3-openpyxl python3-typing-extensions
$ PYTHONPATH=src/ python3 src/bissap/commands/__init__.py
bissap funciona en 3 pasos:
$ bissap collect -t sybase
Copy this command, set the appropriate variables and execute the command. Copy the file `/tmp/dump_bissap.csv` to your host.
Call bissap -d DATABASE.sqlite import -i dump_bissap.csv to continue.
isql -X -w9999999999 -s'|' -U$USER -P$PASSWORD -H$HOST -S$SYSTEM -o /tmp/dump_bissap.csv << EOF
...
GO

$ ... # Manually execute the script
$ scp host:/tmp/dump_bissap.csv npl.csv
$ LOG_LEVEL=debug bissap -d npl.sqlite import -i npl.csv
INFO:src.file_import:Importing the database. Be patient, it may take 5 minutes or more.

DEBUG:src.file_import:Denormalizing the database.
$ bissap -d npl.sqlite -m 001 audit
BWDEVELOPER is vulnerable to 9 RCE(s).
BWDEVELOPER can read 17 sensitive tables.
BWDEVELOPER can execute 20 "juicy" transactions. (SE16, RSUDO, SM49, SE38, SE11, SM69, SU10, SU01, PFCG, SA38, SU01D, SM59, SU03, SU20, AL11, ST04, SUIM, SM01, DB02, SM04)
...
TEST2 can execute 1 "juicy" transactions. (SE11)
$ bissap -d npl.sqlite -m 1 audit -u 'SAP*'
SAP* is vulnerable to 9 RCE(s).
# CG3Z+SM36
> Go to CG3Z (File upload)
> Then create a new external command or edit an existing one
> Then set and save the OS command that you want to run
> Finally execute it using SM36 (Simple job selection/scheduler)
...
$ bissap -d npl.sqlite -m 1 audit --roles
ZDEVELOPER is vulnerable to 1 RCE(s).
ZDEVELOPER can execute 3 "juicy" transactions. (SU01, PFCG, SE38)
$ bissap -d npl.sqlite -m 1 audit --roles -u DEVELOPER
ZDEVELOPER is vulnerable to 1 RCE(s).
ZDEVELOPER can execute 3 "juicy" transactions. (SU01, PFCG, SE38)
(Dado que el usuario DEVELOPER tiene solo un rol, que además es el único rol vulnerable, es normal que la salida sea la misma.)
$ bissap -d npl.sqlite -m 1 audit -r ZDEVELOPER
ZDEVELOPER is vulnerable to 1 RCE(s).
# SE38
Go to SE38 (ABAP editor - create/edit/run ABAP program)
> Create a new ABAP program (but you will need a developer key if you don't have a "developer" account)
> Then execute it using SE38.
