# Exploit Title: Joomla! Component Responsive Portfolio 1.6.1 - 'filter_order_Dir' SQL Injection
# Dork: N/A
# Date: 2018-09-25
# Exploit Author: Özkan Mustafa Akkuş (AkkuS)
# Vendor Homepage: https://extro.media/
# Software Link: https://extensions.joomla.org/extension/rpc-responsive-portfolio/

# Description : An attacker can execute SQL commands through parameters
# that contain vulnerable. An authorized user can use the filtering feature and can fully authorize
# the database or other server informations.
# "filter_type_id, filter_pid_id, filter_search" parameters have the same vulnerable.

# Affected Version: 10.6.1.ga
# Category: WebApps
# Tested on: Win7 Enterprise x86/Kali Linux 4.12 i686
# CVE : N/A
# Technical Description:
# iWay Data Quality Suite Web Console provides web services features. As there is no

# achieve the successful Remote Code Execution on the server
# Proof Of Concept:
> Access the iWay DQS Web Console application section.
> Create an entry for web service and form a sample SOAP request.
> Send below crafted request to the server to confirm the vulnerability

Since commit 615d6e8756c8 ("mm: per-thread vma caching", first in 3.15),
Linux has per-task VMA caches that contain up to four VMA pointers for
fast lookup. VMA caches are invalidated by bumping the 32-bit per-mm
sequence number mm->vmacache_seqnum; when the sequence number wraps,
vmacache_flush_all() scans through all running tasks and wipes the
VMA caches of all tasks that share current's mm.
In commit 6b4ebc3a9078 ("mm,vmacache: optimize overflow system-wide
flushing", first in 3.16), a bogus fastpath was added that skips the
invalidation on overflow if current->mm->mm_users==1. This means that
the following sequence of events triggers a use-after-free:
[A starts as a singlethreaded process]
A: create mappings X and Y (in separate memory areas
far away from other allocations)
A: perform repeated invalidations until
current->mm->vmacache_seqnum==0xffffffff and
current->vmacache.seqnum==0xfffffffe
A: dereference an address in mapping Y that is not
paged in (thereby populating A's VMA cache with
Y at seqnum 0xffffffff)
A: unmap mapping X (thereby bumping
current->mm->vmacache_seqnum to 0)
A: without any more find_vma() calls (which could
happen e.g. via pagefaults), create a thread B
B: perform repeated invalidations until
current->mm->vmacache_seqnum==0xfffffffe
B: unmap mapping Y (thereby bumping
current->mm->vmacache_seqnum to 0xffffffff)
A: dereference an address in the freed mapping Y
(or any address that isn't present in the
pagetables and doesn't correspond to a valid
VMA cache entry)
A's VMA cache is still at sequence number 0xffffffff from before the
overflow. The sequence number has wrapped around in the meantime, back
to 0xffffffff, and A's outdated VMA cache is considered to be valid.
I am attaching the following reproduction files:
vmacache-debugging.patch: Kernel patch that adds some extra logging for
VMA cache internals.
vma_test.c: Reproducer code
dmesg: dmesg output of running the reproducer in a VM
In a Debian 9 VM, I've tested the reproducer against a 4.19.0-rc3+
kernel with vmacache-debugging.patch applied, configured with
CONFIG_DEBUG_VM_VMACACHE=y.
Usage:
user@debian:~/vma_bug$ gcc -O2 -o vma_test vma_test.c -g && ./vma_test
Segmentation fault
Within around 40 minutes, I get the following warning in dmesg:

# Exploit:
# Simply replace "SecurityService.exe" with your preferred payload and wait for execution upon reboot.
1. Content process -> Privileged content process (first_stage.js)
When spawning a new Edge content process, its privilege is determined by its URL. This URL check is performed by the LCIEUrlPolicy::GetPICForPrivilegedInternalPage method in eModel.dll. The method calls several another methods to check the URL. One of them EdgeUrlUtils::IsAboutFlagsResUri is vulnerable. Since it only checks the scheme and whether the URL ends with "/edgehtml.dll/flags.htm", the following URL which will execute arbitrary JavaScript code will be considered to need to spawn a privileged content process.
res://apds.dll/redirect.html?target=javascript:alert(1)//edgehtml.dll/flags.htm
As a navigation triggered from JavaScript to the "res" scheme is not allowed, an additional renderer exploit is required. I used issue 1588 for it.
2. Privileged content process -> Internet Explorer (second_stage.js)
In a privileged content process, we can ask to the host to launch IE for some sites for compatibility. The host then redirects the request to the broker after checking whether the domain of the requested URL is in the IE compatibility view list. Since it only checks the domain, an arbitrary scheme like "file://" can be given.
For this part, a domain in the IE compatibility view list is required to host a samba server. I found that some domains were unregistered, but I just modified the hosts file for testing.
3. Internet Explorer
If the given URL has the "file://" scheme and it's a folder, IE will just open it using ShellExecuteExW. I managed to create a lnk file that bypasses the folder check and executes an arbitrary file. Please find lnk_bug.cc in the PoC.
To reproduce the PoC, you will need a remote machine hosting a samba server and a http server. Note that the PoC uses hardcoded offsets for "Build 17692.rs_prerelease.180609-1317".

# 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.
