SQL injection in the aaa-idm-store-h2 (deleteUser function)

Hello,

I am writing to report a vulnerability in one of the components of Opendaylight, aaa.

With this bug, attackers can SQL inject the component's database(SQLite).

The bug is in /aaa-idm-store-h2/src/main/java/org/opendaylight/aaa/datastore/h2/UserStore.java (deleteUser function).

As we can see, the aaa concats userid information to build a delete SQL query, and it executes the query in SQLite.

However, in line 235, the userid(escaped) is a string. If the user calls the api interface /auth/v1/users/ to add a malicious user, and then calls the deleteUser function to delete the user, it will cause SQL injection.

For example, he can call the api interface /auth/v1/users/ with POST method, it will call the createUser function to add a user. If the user name is:

' or 1=1--+

Then call the api interface /auth/v1/users/' or 1=1--+@DOMAIN_ID with DELETE method, it will call the deleteUser function to delete the user. And the SQL query is:

DELETE FROM AAA_USERS WHERE userid = ‘’ or 1=1—+’@DOMAIN_ID

And all the elements in the AAA_USERS table are removed due to this malicious query.

Please consider fixing this security vulnerability as soon as possible.

Best wishes,

Chunyang Han
