Searching For Exploits
Searching For Publicly Available Exploits
After identifying a potential vulnerability within a target or a service running on a target, the next logical step is to search for exploit code that can be used to exploit the vulnerability.
Exploit Code: Exploit code can easily be found online. However, it is important to note that downloading and running exploit code against a target can be quite dangerous. It is recommended to analyze the exploit code closely to ensure that it works as intended.
Legitimate Exploit Databases: There are a handful of legitimate and vetted exploit databases that you should use when searching for exploits online:
Packet Storm (Cyber News + Exploits + More)
Searching For Exploits With SearchSploit
Offline Exploits: In some cases, access to online exploits may not be available, requiring the use of locally available exploit sources.
Exploit-db Database: The entire Exploit-db database of exploits is pre-packaged with Kali Linux, providing access to all exploits locally.
SearchSploit Tool: The Exploit-db offline database of exploits can be accessed and queried using a tool called SearchSploit.
Storage Location: All exploits are stored in
/usr/share/exploitdb.
Fixing Exploits
Before executing any exploit sourced from external or internal origins, it is imperative to conduct a comprehensive review of both the code and accompanying documentation. Understanding the exact functionality and prerequisites of the exploit is crucial for successful server exploitation.
Always ensure a thorough grasp of the exploit's operations and potential implications prior to proceeding. Unauthorized or careless use of exploits can result in significant consequences.
Cross-Compiling Exploits
Executable Code Development: Exploit code may often be developed in languages like C, C++, or C#. Consequently, it will need to be compiled into a Portable Executable (PE) or binary format.
Cross-Compilation Definition: Cross-compiling refers to the process of compiling code intended for one platform on a different platform.
Penetration Testing Skills: As a penetration tester, it's essential to possess the necessary skills for compiling exploit code written in C and its variants.

64-bit Compilation:
32-bit Compilation (with Winsock library):
Compiling ELF Binary (for Linux/Unix):
You can also access pre-compiled exploits on the Exploit Database GitHub repository.
