SQL injection in the aaa-idm-store-h2 (deleteDomain 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/DomainStore.java (deleteDomain function).

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

However, in line 197, the domainid(escaped) is a string. If the user calls the api interface /auth/v1/domains/ to add a malicious domain, and then calls the deleteDomain function to delete the domain, it will cause SQL injection.

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

' or 1=1--+

Then call the api interface /auth/v1/domains/' or 1=1--+ with DELETE method, it will call the deleteDomain function to delete the domain. And the SQL query is:

DELETE FROM AAA_DOMAINS WHERE domainid = ‘’ or 1=1—+’

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

Please consider fixing this security vulnerability as soon as possible.

Best wishes,

Chunyang Han
