Another DoS in MS Publisher 2010

During last week I found few more NULL ptrs in MS Office Publisher (2010 for Windows 7).

Mail me if you want the poc (I already sent it to MS 3 months ago).

Maybe later I will post more details. For now it looks like a DoS only.

Cheers ;)

BrokenWebapps - CTF writeup

When I was looking for a new CTF, I found interesting website with multiple CTFs ISO and VM images, prepared (vulnerable) to hack. I decided to try OWASP Project called BrokenWebapps (VM I’ve tried was OWASP_Broken_Web_Apps_VM_1.2).

I prepared the VM and started another one (this time with Kali2.0 – both on VirtualBox). As far as I know, we can treat this VM as a big WWW server, hosting multiple webpages.

[EN] SOAP testing

During one of last projects I needed to test some webservices.

I was wondering: if I can do it with Burp or by manual testing,
maybe I can also write some quick code in python...

And that's how I wrote

During couple of last days I was checking lcamtuf’s American Fuzzy Lop against some (“non-instrumented”) binaries. 

I was wondering, what will happen if I will run it against Java… ;)

I was looking for some sources, but unfortunately I wasn’t able to find any. Next thing was checking where I have Java installed (so I will know what/where I can check. Kind of ‘test lab’ was: Ubuntu 12, Kali Linux, WinXP, Win7. (Exact version of Java installed on that OS’s you will find below.)

SQLI in e107 CMS

During last few weeks in the middle of time I was doing also some source code review.
That's how I found sqli bug in admin panel in e107 CMS. After a fast response from e107 Team,
fix was created.

This bug was found in e107_2.0_full_beta1 version. I don't know if other versions are also vulnerable.

Details about the vulnerability (even when it's in admin panel) will not be published for now.

Stay in touch. ;)
