GAQM Exam CPEH-001 Topic 6 Question 30 Discussion

Actual exam question for GAQM's CPEH-001 exam
Question #: 30
Topic #: 6
[All CPEH-001 Questions]

Bill has successfully executed a buffer overflow against a Windows IIS web server. He has been able to spawn an interactive shell and plans to deface the main web page. He first attempts to use the ''Echo'' command to simply overwrite index.html and remains unsuccessful. He then attempts to delete the page and achieves no progress. Finally, he tries to overwrite it with another page again in vain. What is the probable cause of Bill's problem?

Show Suggested Answer Hide Answer
Suggested Answer: D

The question states that Bill had been able to spawn an interactive shell.By this statement we can tell that the buffer overflow and its corresponding code was enough to spawn a shell. Any shell should make it possible to change the webpage.So we either don't have sufficient privilege to change the webpage (answer D) or it's a honeypot (answer A). We think the preferred answer is D

He probably needs to check the shell setup first.

Wait, can you really not overwrite files with a buffer overflow?

You can definitely use a buffer overflow for that!

I think it's just a permissions issue.

Sounds like a honeypot to me.

I feel like I’ve seen a question like this before, and it was about permissions being set to read-only. That could definitely be the issue.

I’m not sure, but I think if the shell isn’t functioning properly, he might need to re-establish it before trying again.

I remember reading that file permissions can really mess up attempts to overwrite files. Maybe that's what's happening here?

I thought buffer overflows could lead to defacing pages, but now I’m questioning if there’s a limitation on what can be done afterward.

I've learned about this in class, so I think I can answer this. An upstream project has more build steps than a downstream project.

Based on my understanding, I believe the correct answer is B - only the Compliance Manager can modify controls in the draft state. I'll double-check that before submitting.

This seems like a tricky one. I'll need to think through the network topology and project relationships carefully.
