Getting a victim to open a file is a proven effective way to attack an organisation - phishing and social engineering work, very well. So assume that part of the attack is low effort if you or your organisation is a target.
As regards anything that sounds like complex crafting of a payload, if it can be created it will. The market in attacks flows down from ...
The thing here is all about reading the sudo -l command's result well as @vsja mentioned in the comments. Focusing on the results and the operation system my research ended up with this thread, which mentions to use the absolute path given in the sudo -l output.
I know exactly what you are talking about and you are almost on the right track.
the sudo is letting you run /usr/bin/vi but in the same way you can't just do sudo vi somefile.txt, maybe there is a reason you can't do sudo /usr/bin/vi somefile.txt
For those wondering, I am hesitant to give an exact answer because this is an active CTF and it is discouraged ...
I think you're confused about privilege escalation. First of all privilege escalation is meant to bypass restrictions for a low privileged user in order to execute tasks as a high (root) privileged user.
Executing a privilege escalation exploit as root is kind of useless (just to state the obvious)
What right can kernel based exploit give me
Client side exploits are not necessarily attacks on the client!
Many web servers invoke authentication and security via client side functionality. For example they may send back a sub-path or ID in a query response, expecting the client code to hold and reuse this content appropriately (cookies work this way). The problem is that the client code and data is ...
In the classic client/server architecture, there is the server which serves requests initiated by the client, and the client which makes said requests. An example of the client/server architecture is the web, where a web server communicates with a web browser (the client). A client-side exploit is thus one which attacks or influences the client. It is ...

No, fuzzing is not a requisite for exploit development.
as google tells me that it is not possible to reverse engineer a C/C++ .exe file back to source code, that you only get assembly?
Though it is technically true that the exact source code that a binary was compiled from cannot be recovered via decompilation, this also somewhat misleading, as your ...
Exploit - An exploit is the means by which an attacker, or penetration tester for that matter, takes advantage of a vulnerability
within a system, an application, or a service. An attacker uses an
exploit to attack a system in a way that results in a particular
desired outcome that the developer never expected. Common exploits
include buffer ...
This appears to be an attempt to exploit the recent Exim MTA Vulnerability, CVE-2019-10149.
There is a patch for Exim4 to address this issue.
