Problems what we faced:

  • Still need to get everyone a VM with DVWA running

Things what we plan to do:

  • Copy Paste documentation tasks to Wiki :)
  • Divide OWASP tasks

Wednesday - 27.03.13

Things what we did that day:

  • Meeting with clients. It was very open-minded meeting. We got to know more about requirements.
  • Analysing the user needs. We discussed face to face with our client and mentor (Margus Ernits) what needs to be done in order to perform security testing. Also, we found some tools from the Internet, which we can use for testing purposes.
  • We divided roles and shared our areas of competences. Also, we agreed that one should not be doing always the same thing, so we can share our work with eachother.
  • Estonian ICT Presentation and Wireshark practice. Wireshark was more-less known for everyone in our team. Despite that fact, we all found something enjoyable and new from Antti's presentation and Wireshark.
  • Estonian members made Study Information System presentation to Finnish and Lithuanians. We talked about some potential vulnerabilities (such as VÕTA declaration, file upload, sending messages, voting system)

Problems what we faced:

  • As none of us have done security testing before, we have a lot to learn before we can actually do something. But I think with such a team as we are, it's nothing.

Things what we plan to do:

  • Estonian members are going to study last year's report and going to make a short overview to other members about it.
  • We are going to study OWASP Top 10 vulnerabilities and everyone of us is going to make a short presentation to others about what they have learned.
  • We are going to ask in demo (development) environment if they can open a new survey for us, new declaration period; Also we need teacher and demo accounts, in order to test teacher's side as well, because teachers have a little more access than students (grades, information about student etc).
  • In demo environment we are going to test new functions (what haven't been included in main environment, yet) - as there's some new functionality.

Thursday - 28.03.13

Things what we did that day:

  • OWASP TOP 10 presentations: Everybody presented on their subjects + discussion (slides)
  • Discussed the schedule and to-do list for next days
  • Discussed some potential vulnerabilities of SIS
  • Made shared Googledoc to document the testing and to exchange information. Also we made Skype group in order to share files effectively and fast.
  • Prepared software for testing (Backtrack, Kali)

Problems what we faced:

  • There is a lot of information, we need to focus on something and just start. There is no such thing as start-line ("Start here and go this way"), we will just need to start and see what we will find.

Things what we plan to do:

  • Find attack examples for the vulnerabilities
  • Try them out on DVWA
  • Get familiar with Tamper Data, Kali and Backtrack
  • Familiarise ourselves with XSS, Injection, CSRF before testing SIS
  • See how to get authentication info from POST and GET

Security threat of a day

  • There are three environments of SIS. Live, demo and developer. We found out that developer environment is accesible with our live users and passwords. What's more -> developer environment has LIVE data!!! Like! Does that ring any bell to you? NEVER, we mean like NEVER use live data (data, grades, schedule, students, personal ID-s etc) in demo/developer environment!

Friday - 29.03.13

Things what we did that day:

  • Learned how to perform attacks. We learned different attack methods and tried them out.
  • Learned how to use different automated tools. Automated tools are not very efficient to SIS, but still - there might pop up something interesting from the results. Results are saved for later analysis.
  • Talked about last year's experience. Tried if most of the security holes are patched or not.

Problems what we faced:

  • We need student access to developer environment
  • We need new survey and declaration period opened (we asked Margus, he promised to give our request to someone who can make it)

Things what we plan to do:

  • Analysis of the results needs to be done
  • Learn a little bit more about attacks
  • Create some attacks
  • Start to test simpler attacks to SIS

Security threats of the day:

  • One can see other student's exam plan just by chaning student_id value in the URL (you don't need to be logged in). You cannot see his/her name directly, but according to security holes now: See the schedule, just change ID - you get the name. Or if you are logged in, then you can go to "My data" and just change ID from the URL again.

For example: https://itcollege.dev.ois.ee/en/schedule/agenda?student_id=2322

Saturday - 30.03.13

Things what we did that day:

  • Visiting Tallinn TV Tower
  • Visitinig The Seaplane Harbour

Sunday - 31.03.13

Free day

Monday - 01.04.13

NB! April fools' day! Beware!

Things what we did that day:

  • We analyzed student information fields in "My data" section
  • We test different sections and tried to change user IDs - luckily these are safe now.
  • Tried to use HTTP for different areas in SIS. Luckily, everything is forced to HTTPS.
  • Study materials testing. If study materials are available to everyone (public), then it is possible to download them from HTTP and/or HTTPS!
  • Tried reflected XSS, most SIS areas escape "bad characters" out from input boxes.
  • As the SIS allows academicians (lecturers) to change their picture, we tried to insert some malicious code into picture. Scenario was that when someone opens the picture, some bad things will happen. This did not work in SIS. Students are not allowed to change their picture due to security reasons (for example: other person taking exams claiming he/she is someone he/she is not)

Problems what we faced:

  • Still no new declaration etc opened for us. Maybe tomorrow?

Things what we plan to do:

  • We strongly hope that there will be new declaration period, survey, scolarship application and VÕTA opened for us for tomorrow morning, because we could test them as well and we don't have much time left.
  • Go deeper with different attacks and methods.

Security threat's of the day:

  • SIS (Study Information System) is vulnerable to BEAST attack, because it uses RC4 encryption algorithm in SSL. We as a test-team are not capable to perform this kind of attack, thus we cannot test how far can we go, but this is a threat to whole system. BEAST attack can sniff authorized user's cookies and then grant access to attacker.
  • There's no character limit for input fields (search, names). This can lead to DOS-attack because attacker can send multiple requests with long URLs and then server freezes.
  • Calendar: there's no limit or check if user have just typed numbers. Error is rendered back to user, but it is escaped.
  • There are some developer's notes left in different SIS parts (not only in developer environment).

Tuesday - 02.04.13

Things what we did that day:

  • Visiting Skype office.
  • Learning the principles of good presentation to put into practice tomorrow and on Thursday.
  • SIS is using a field called "security_key_sis_global". This form value does not change and is based on user data. We have found out that this does not change even on change of password, so that means, this has to be calculated from person's name and/or username and/or personal ID code and/or user_id value. We have assumption that this is a SHA1 hash, as it is 40 characters long. Maybe salted, maybe not? Anyway, this could be a threat to SIS in long term perspective.
  • Studied the OWASP ASVS (Application Security Verification Standard) with SIS in mind. Marked the requirements we can not check for (because we do not have the source code etc), the requirements we believe are met and those that need further testing.
  • Got the chance to insert a new VÕTA (APEL) request that also allows for uploading files. This is interesting because it might be possible to upload a file containing malicious code.
  • The SIS does not ask for password when changing the personal e-mail address. This is a risk, because this is the mail address SIS sends a password reset link to if the user clicks on "Forgot my password".

Problems what we faced:

  • Really would have liked to have more time to test.

Things what we plan to do:

  • Prepare and rehearse the presentation
  • Look further into the e-mail modification issue.
  • Finalise ASVS review

Wednesday - 03.04.13

Things what we did that day:

  • Studied and analysed ASVS. Went through requirements and aspects about web application security, analysed what applies to SIS and what not.
  • We learned and practiced public presentation. Discussed structure and divided roles. Rehearsed presentation to "audience".
  • SIS testing (security token), javascript upload, tried to find XSS vulnerabilities in APEL (VÕTA) application and file upload areas etc.

Problems what we faced:

  • Lack of time. Doing presentation and rehersal took so much time which could be used for testing SIS. Also, testing SIS took so much time, which again could be have been used for rehearsal.

Things what we plan to do:

  • We want to review and rehearse our final presentation.
  • Update our documentation in Wiki.
  • Upload and link presentations to persons and fill gaps in documentation.

Thursday - 04.04.13

Things what we did that day:

  • Dress rehearsal. Updated presentation according to feedback and capabilities.
  • Updated documentation to Wiki and uploaded missing presentations.
  • Personal input section filling in Wiki.
  • Went bowling. :)

Problems what we faced:

  • Sometimes one minute feels like it is not a minute. :)

Things what we plan to do:

  • Final documentation (link to Google docs).
  • IP feedback
  • Summarisation

Friday - 05.04.13

Things what we did that day:

  • Discussion about today's plans.
  • Upgraded and linked final documentation from Google Drive (aka Google Docs) (link can be found in Materials#Materials_.28slides_etc.29 section and #Final documentation section).
  • Every member wrote a feedback to Wiki page
  • Every member wrote a feedback according to requirements of the Intensive Programme (Erasmus feedback)
  • IP summarisation.
  • Farewell party at St. Patrick's.

Problems what we faced:

Final documentation

Analysis

Solution

IP Feed-back

Feedback from Sten Aus

I liked IP very much. It was very mindopening experience and definitely I am going to suggest this to my friends, so they can participate next time. I think that it is very good to participate in multicultural group, where all the participants are from different countries. I did not like that we had to sit so much in lectures. :) And from time to time it was hard to understand the meaning of lecture, I could not link it to our project. But I think it will come to me after a few days, months or years, as a lot in this life - you don't know the purpose yet, but you will find it out in the future.

I enjoyed food a lot, it was a good choice to take lunches and dinners from Rahva Toit. :) Also, the pricing was good.
