The objective of this challenge is to gain access to a PC by exploiting vulnerabilities in the Caesar 2 system.
The first step in any exploitation process is to gather as much information as possible about the target system. Using basic network scanning techniques: caesar 2 getintopc
nmap -sV -p 1-65535 <target IP> The scan reveals that several ports are open, but one port in particular catches our attention: and 80 (HTTP) . The objective of this challenge is to gain
Upon closer inspection of the web application, entering a string in the caesar= parameter results in an encrypted string. This indicates the application might be using a Caesar cipher for encryption. Further testing reveals that the shift is . Upon closer inspection of the web application, entering
The hint "caesar 2" suggests a possible Caesar cipher vulnerability. A Caesar cipher is a type of substitution cipher in which each character in the plaintext is 'shifted' a certain number of places down the alphabet.
Knowing the shift value, we can potentially decode messages or create encoded messages that the system can understand. However, to gain access to the PC, we need to find a way to leverage this vulnerability.
