2024 CWE Top 25 Most Dangerous Software Weaknesses: Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119)

by

CWE-119 pertains to scenarios where software operations exceed the allocated memory buffer’s boundaries, leading to buffer overflows. This flaw can result in various adverse consequences, including data corruption, application crashes, and security vulnerabilities exploitable by attackers. A buffer overflow occurs when data written to a memory buffer exceeds its storage capacity, potentially overwriting adjacent memory locations.

2024 CWE Top 25 Most Dangerous Software Weaknesses: Improper Input Validation (CWE-20)

by

Improper input validation occurs when a software application fails to verify that input received is within the expected range, format, type, or value before processing. This weakness paves the way for a variety of security exploits, including injection attacks, buffer overflows, and data manipulation, which can compromise application functionality and user data.

2024 CWE Top 25 Most Dangerous Software Weaknesses: Use After Free (CWE-416)

by

At its core, a Use After Free vulnerability occurs when a program continues to use memory after it has been freed or deallocated. This behaviour can result in undefined behaviour, ranging from crashes and data corruption to critical security breaches, including arbitrary code execution.

2024 CWE Top 25 Most Dangerous Software Weaknesses: Out-of-Bounds Read (CWE-125)

by

Out-of-Bounds Read occurs when a program reads data past the allocated boundary of a buffer. This behaviour typically arises from improper validation of input data or incorrect indexing in memory operations. By exploiting this weakness, attackers can gain unauthorised access to sensitive information, potentially leading to security violations.
