# Tests fonctionnels du PoC BunkerWeb
|
||||
# Lance une série de requêtes légitimes et malveillantes au travers du
|
||||
# WAF et compare le code HTTP obtenu au comportement attendu.
|
||||
#
|
||||
# Usage : bwpoc-tests.sh [--direct] [--only <motif>]
|
||||
# --direct rejoue les attaques directement sur les applis, sans WAF
|
||||
# (nécessite apps_direct_access_sources, voir README)

||||
# --only ne lance que les tests dont le titre contient <motif>

# Variables (fichier bwpoc-tests.env à côté du script, ou environnement) :
|
||||
# WAF_IP, DOMAIN, APPS_IP, PORT_WWW, PORT_SHOP, PORT_API
|

#
|
||||
# ATTENTION : les derniers tests provoquent volontairement le
|
||||
# bannissement de votre IP sur api.<domaine> (BAD_BEHAVIOR_BAN_TIME).
