Vulnerabilities in the Java class library which an application relies upon for its security; A vulnerability in the Java platform will not necessarily make all Java applications vulnerable. When vulnerabilities and patches are announced, for example by Oracle, the announcement will normally contain a breakdown of which types of application are ...
Log4Shell (CVE-2021-44228) is a zero-day vulnerability reported in November 2021 in Log4j, a popular Java logging framework, involving arbitrary code execution. [2] [3] The vulnerability had existed unnoticed since 2013 and was privately disclosed to the Apache Software Foundation, of which Log4j is a project, by Chen Zhaojun of Alibaba Cloud's security team on 24 November 2021.
To prevent code injection problems, the person could use secure input and output handling strategies, such as: Using an application programming interface that, if used properly, is secure against all input characters. Parameterized queries allow the moving of user data out of a string to be interpreted.
This type of vulnerability would be bad enough if it was limited to just one product or brand. But because Log4j is such a ubiquitous technology, the effect of this will be exponentially higher.
The Java programming language and Java software platform have been criticized for design choices including the implementation of generics, forced object-oriented programming, the handling of unsigned numbers, the implementation of floating-point arithmetic, and a history of security vulnerabilities in the primary Java VM implementation, HotSpot.
Secure coding is the practice of developing computer software in such a way that guards against the accidental introduction of security vulnerabilities.Defects, bugs and logic flaws are consistently the primary cause of commonly exploited software vulnerabilities. [1]
These vulnerabilities leave applications open to exploitation. Ideally, security testing is implemented throughout the entire software development life cycle (SDLC) so that vulnerabilities may be addressed in a timely and thorough manner. There are many kinds of automated tools for identifying vulnerabilities in applications.
