Description

Hello 3APA3A!

I want to warn you about security vulnerabilities in MODx. This is the first part of the vulnerabilities in this CMS (the first 19 vulnerabilities).

These are Brute Force and Full path disclosure vulnerabilities in MODx. It's about 0.x and 1.x (Evolution) versions of MODx CMS. In 2.x (Revolution) versions of MODx there are part of these holes and part of new holes - I've wrote separate advisory concerning it.


Affected products:

Vulnerable are MODx 1.0.6 and previous versions.


Details:

Brute Force (WASC-11):

In login form (http://site/manager/) there is not reliable protection from Brute Force attacks.

At that at some web sites the blocking is used after multiple unsuccessful attempts. But it's ineffective - the password can be picked up before blocking will trigger (as it was during my pentest), it's short-term and it works for concrete account, i.e. it's possible to pickup passwords to other unblocked accounts.

Full path disclosure (WASC-13):

Some of these FPD holes concern engine and some concern plugins to it.


Timeline:

2012.06.27 - announced at my site. 2012.06.28 - informed developers about the first part of vulnerabilities. 2012.06.30 - informed developers about the second part of vulnerabilities. 2012.07.28 - informed developers about vulnerabilities in MODx Revolution and reminded about previous two letters. 2012.07.28-2012.10.31 - during conversation with developers about MODx Revolution, I was constantly reminding them, that I've sent them info about holes in Evolution and I can resent them, because it was clear that they missed it (they only were answering concerning Revolution). 2012.11.02 - after developers said they want to see this information (missed by them in June), I've resent the first two letters to the developers. 2012.11.17 - disclosed at my site (http://websecurity.com.ua/5926/).
