Summary0027495: CVE-2020-28413: SQL injection in the parameter "access" on the mc_project_get_users function throught the API SOAP.

Throught the function mc_project_get_users on the API SOAP, it's possible to inject SQL commands in the parameter "access". So, creating an union select query, it's possible generate a blind sql using the IF funcion on the database to discover the different data on the application like passwords hash. Also, it's possible to exploit it using SQLMap.

Steps To Reproduce

1- start up burp suite
2- start up soap ui , configure proxy and create new soap project
3- open the mc_project_get_users function and insert "username", "password", "project_id" could be 0 and "access" let it emply
4- send request and look the SQL error
5- save the request on burp
6- insert the request file in sqlmap to read the databases sqlmap -r burp_file --dbs --batch

Also, you can make it manually
5- now, insert a SQL query on the "access" input (0 or 1=1) and send request
6- now, insert a SQL union select query on the "access" input (0 union all select 900,2,3,4 order by id desc) and send request

Additional Information

According cvss 3.1

The CVE is Reserved.

The solution more closer is make a parametrization in the SQL queries and evade to insert parameters directly on the query.

TagsNo tags attached.

Many thanks for your report and responsible disclosure.

I believe that the vulnerability you discovered, should be fixed in the current master branch (2.25.0-dev since commit MantisBT master 682a182d ).

Would you be able to test again to confirm, using the latest nightly build ?

The code in project API allowing the SQL injection by not using query parameters exists at least since 1.0.0.a1.

The exploitable vulnerability via SOAP API described here, exists since 1.1.0a4.

@ethicalhcop waiting for your confirmation that code in master branch is no longer vulnerable (as far as I can tell, it is not).

let me tell you that I retest the app again in the bb10211 compilation and the vulnerability was fixed successfully.

So, remember that I will make the public divulgation at December 11.
The mantisbt team have any protocol to make public the vulnerability for pentesters?

Regularly I do a walkthrought and write a script to exploit the vulnerability , I don't know if do you have some protocol.

Not sure what you mean by protocol.
When a patch for a security issue is ready, we just release a new version including the fix and announce it via our usual channels, referencing the CVE ID if applicable.

@ethicalcop, I'm sorry, but the December 11 deadline you set might turn out to be a little short, as I have a series of other security issues that I'm still working on, and I'm not 100% sure at this time, that I'll have everything ready by Friday.

Would you mind postponing your going public by a few days ? I'll give you the green light as soon as I'm done.

@ethicalhcop Thanks for your understanding. I'll ping you here as soon as I'm ready.

next saturday december 26, I will to participate on a little security meetup where I will to talk about the CVE !

Thanks for the heads up. I was hoping to finalize fixing the other issues last week-end but unfortunately didn't have enough time.

So now there are a few options (in my order of preference / feasibility):

  1. when you make your presentation, you make it clear that the issue is has not yet been fully disclosed to the public and so it should be kept confidential
  2. I release 2.24.4 with only some of the other issues fixed, and plan for another 2.24.5 (probably best, but takes some effort on my end)
  3. I manage to finalize fixes and release 2.24.4 with everything as planned initially before 26th (unlikely)

Let me know your thoughts.

Fix SQL injection in Project API

The query's where clause in project_get_all_user_rows() was built by
concatenating an unsanitized variable, allowing SQL injection via
SOAP API's mc_project_get_users() function using a crafted request.

Relying on DbQuery object ensures use of query parameters, making the
SQL injection impossible.

Partial backport from commit 682a182d4b2ae9abd2edb9c2ed40eb80723988b1.
