Exploit ; from the English verb to exploit, meaning "to use something to one’s own advantage"
What are exploits?
Is a piece of software, a chunk of data, or a sequence of commands that takes advantage of a bug or vulnerability to cause unintended or unanticipated behavior to occur on computer software, hardware, or something electronic "usually computerized" Such behavior frequently includes things like gaining control of a computer system
Exploits are ultimately errors in the software development process that leave holes in the software’s built-in security that cybercriminals can then use to access the software and, by extension, your entire computer. Exploits are commonly classified according to the type of vulnerability
Exploits are commonly classified according to the type of vulnerability they exploit, such as zero-day, DoS or related DDoS , spoofing and xxs
Since exploits take advantage of security holes in software, a user has no way of knowing if they’ve been affected until it’s too late
There are several methods of classifying exploits. The most common is by how the exploit communicates to the vulnerable software
remote exploit works over a network and exploits the security vulnerability without any prior access to the vulnerable system or local exploit requires prior access to the vulnerable system and usually increases the privileges of the person running the exploit past those granted by the system administrator .
Exploits vs Vulnerability
a vulnerability is a weakness in a software system. And an exploit is an attack that leverages that vulnerability. So while vulnerable means there is theoretically a way to exploit something ( a vulnerability exists) exploitable means that there is a definite path to doing so in the wild. Naturally, attackers want to find weaknesses that are actually exploitable. As a defender, being vulnerable isn’t great, but you should be especially worried about being exploitable
This alone can go a long way towards reducing your exposure to known and unknown vulnerabilities and make it that much harder for attackers to be successful when vulnerabilities become exploits.
Bug
A bug is any defect in a product. A vulnerability is bug that manifests as an opportunity for malicious use of the product , A security bug or security defect is a software bug that can be exploited to gain unauthorized access or privileges on a computer system. Security bugs introduce security vulnerabilities by compromising one or more of
Authentication of users and other entities
Authorization of access rights and privileges
Data confidentiality
Data integrity
Security bugs need not be identified nor exploited to qualify as such.
Security bugs generally fall into a fairly small number of broad categories that include:
Memory safety ( Buffer Overflow and dangling pointer bugs)
Race condition
Secure input and output handling
Faulty use of an API
Improper use case handling
Improper exception handling
...
A software bug is an error, flaw, failure or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. The process of finding and fixing bugs is termed "debugging" and often uses formal techniques or tools to pinpoint bugs, Most bugs arise from mistakes and errors made in either a program's source code or its design, or in components and operating systems used by such programs. A few are caused by compilers producing incorrect code. A program that contains many bugs, and/or bugs that seriously interfere with its functionality, is said to be buggy (defective). Bugs can trigger errors that may have ripple effects. Bugs may have subtle effects or cause the program to crash or freeze the computer. Other bugs qualify as security bugs and might, for example, enable a malicious user to bypass access controls in order to obtain unauthorized privileges .
