This was regarding my last mail to Mozilla in which I had sent an Advisory to Mozilla about the Clickjacking. But as always there was again slight differences between mine and their definition of Clickjacking.Then I verified the case with none other than RSnake and Jeremiah, who replied me:

Yes, this is one form of clickjacking.
And this is what Jeremiah says via LinkedIn mail:

File Upload through Null Byte Injection

Sometimes, during file upload we come across situation wherein there would be check on the file extension at the client side as well as server side too. If the application does allow only .jpeg extension to be uploaded, the client side java script checks for the extension of the file before passing the request. We all know that how easily this can be defeated. Some applications, checks for the extension at the server side also. That's not easy to bypass. However there are some ways with which it still can be bypassed. Most of server side scripts are written in high level languages such as Php, Java etc who still use some C/C++ libraries to read the file name and contents. That leads to the problem. In C/C++ a line ends with /00 or which is called Null Byte. So whenever the interpreter sees a null byte at the end of the a string, it stops reading thinking it has reached at the end of the string. This can be used for the bypass. It works for many servers, specially php servers. T...

'Information Leakage-Improper Error Handling' dropped

From Owasp Top 10 2010 List, the issue 'Information Leakage-Improper Error Handling' has been dropped. But it's not the final list,its child release actually. Bu I feel it shouldn't be set aside because its still the one of the prevalent issues these days. That's why I mailed to Dave Wicher: Hi Dave, Excellent work, Congrats! Just one little query- Don't you think that Information Leakage & Improper Error Handling still deserves to be in Top 10? Dave replied: This topic is clearly a very prevalent issue that deserves attention by most organizations. However, the typical impact of such a flaw is usually very low. Therefore, the overall risk of this type of flaw is lower than the other items in the top 10, which is why it was replaced in this update with one of the 2 new items. Regarding dropping Info Leak/Error handling - It is incredibly prevalent, no question. But their impact is typically very low, so the overall risk is low, which is why it fell out of t...

Breaking Excel password protection

If you came across an excel sheet asking for password for allowing to make any changes into it, you may want to unprotect it. All we need to do is to edit the xml file which comes intrinsically packaged with Excel 2007 or 2010. But what about Excel 2003? For that, open the Excel 2003 file within Excel 2007, save it as xlsx file. So, keep in mind all the Excel files below 2007 version, you need to convert them as Excel 2007 with extension .xlsx. Now here are the steps for doing that: 1. Open the Excel 2003 file (e.g. Secret.xlsx) and save it as .xlsx (Excel 2007) format. If you already have Excel 2007 file, then no need for any conversion. 2. Now change the extension of the above file to .zip and extract the zipped file. Browse through the file in the extracted folder and go to: <LocalPath>\Secret\xl\worksheets.   3. Now open the sheet/ sheets you want to remove protection in any xml editor. Look for keywords such as 'sheetProtection' or 'workbo...
