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Details about the vulnerability (even when it's in admin panel) will not be published for now.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

[EN] Old nasm sigsegv 0day

Like before, I wrote another poc to get shell via overflow in old nasm.
Check it out:

[EN] Flex 2.5.33 (2) 0days

I was testing some old bugs in one old distro, and that's how I found sigsegv in flex (2.5.33).

Below is the proof of concept:

[EN] Analysing malicious PDF - part 2

This time we will check 2 PDF's (because I decide that it will be more fun than just posting about one ;)). Beside that - those 2 files contains different method for delivering the payload, so we will check all of them.

[EN] Analyzing Malicious PDF

Reading Contagio Blog I found few examples of malicious PDF files.

Today we will check one of them. :)

During PDF analysis many times we will use peepdf and Malzilla.
Also this time, those tool will help us to understand what's going on with
our PDF file.

Let's run peepdf on this file. As we can see there is some JavaScript object.
Let's examine this by "object 7" command:

[EN] Obfuscated case - JSredirector

Today we'll check some "obfuscated" JavaScript code. I found this example (named
'JSredirector')  on this site. Thanks again! ;)

So... Unzip the file and you will find index.html with JS code.

Index.html contains encoded JS code:

[EN] Malware analysis – Fake AV Downloader (part 1)

1.    Thanks for the sample file(s)

After writing my last article about malware analysis for Android[1], I decide to check some threats that may come from webpages. Today we can see more advertisement on web than it was few years ago. In case of malicious pages, “advertisements” added there now, more often probably will try to steal your data by installing some malware on your computer or by redirecting you to webpage containing exploit code for your browser(‘s plugin).

Few nice examples of ‘webpages’ like this, I found (again) on great Mila’s blog[0]. Thank’s again! ;)

[EN] Fun with American Fu(n)zzy Lop

Last days I was doing a little research about 'how this crazy afl works'.  ;)
"American Fuzzy Lop" it's an excellent tool created by lcamtuf.

Now it's a good moment to check the documentation of 'afl' if you want
some nice details about using it.
