# Exploit Title: H2 Database 1.4.196 - Remote Code Execution
|
|
# Google Dork: N/A
|
|
# Date: 2018-09-24
|
|
# Exploit Author: h4ckNinja
|
|
# Vendor Homepage: https://www.h2database.com/
|
|
# Software Link: http://www.h2database.com/h2-2018-03-18.zip
|
|
# Version: 1.4.196 and 1.4.197
|
|
# Tested on: macOS/Linux
|
|
# CVE: N/A
|
|
|
|
# This takes advantage of the CREATE ALIAS RCE (https://www.exploit-db.com/exploits/44422/).
|
|
# When the test database has a password that is unknown, it is still possible to get the execution
|
|
# by creating a new database. The web console allows this by entering the name of the new database
|
|
# in the connection string. When the new database is created, the default credentials of
|
|
# username “sa” and password “” (blank) are created. The attacker is logged in automatically.
|
|
# The attached Python code, modified from 44422, demonstrates this.
