What is binary vulnerability?
Description. Binary planting is a general term for an attack where the attacker places (i.e., plants) a binary file containing malicious code to a local or remote file system in order for a vulnerable application to load and execute it.
What is Remote Code Execution?
One well-known vulnerability in web applications is one that is known as Remote Code Execution. In this type of vulnerability an attacker is able to run code of their choosing with system level privileges on a server that possesses the appropriate weakness.
What techniques analyze binary?
Binary code analysis, also referred to as binary analysis or code review, is a form of static analysis the does threat assessment and vulnerability testing at the binary code level.
What causes Remote Code Execution?
RCE is caused by attackers creating malicious code and injecting it into the server via input points. The server unknowingly executes the commands, and this allows an attacker to gain access to the system. After gaining access, the attacker might try to escalate privileges.
Is there a way to detect vulnerability in binary code?
This paper presents a method for exploitable vulnerabilities detection in binary code with almost no false positives. It is based on the concolic (a mix of concrete and symbolic) execution of software binary code and the annotation of sensitive memory zones of the corresponding program traces (represented in a formal manner).
Are there any vulnerabilities for format string functions?
This is a kind of vulnerability that utilizes a format string function to achieve information leak, code execution, and DoS. These vulnerabilities have become rare nowadays, as most modern compilers produce warnings when format functions are called with non-constant strings (which is the root cause of this vulnerability).
Why do we use binary code instead of source code?
The use of binary code instead of source code is motivated by the fact that it contains all the necessary details to accurately find exploitable vulnerabilities. Such approach best responds to the objective of generating no false positive.
How is software code analysis used to detect vulnerabilities?
Software code analysis is one of these methods aimed to detect vulnerabilities early in software life cycle. This method has many drawbacks. We cite the problem of “false positives” where the analysis tool detects vulnerabilities, which in fact are not existing.
