2024 CWE Top 25 Most Dangerous Software Weaknesses: Integer Overflow or Wraparound (CWE-190)

Integer Overflow occurs when an arithmetic operation attempts to create a numeric value that exceeds the maximum limit of the data type used to store it. Similarly, Integer Wraparound happens when the numeric value “wraps around”, cycling back to the minimum limit.

NULL-Pointer_Dereference-KrishnaG-CEO

Understanding CWE-476: NULL Pointer Dereference

In software development, a NULL pointer is a pointer variable that does not reference any valid memory location. Dereferencing such a pointer—attempting to access the memory it supposedly points to—results in undefined behaviour. In many systems, this leads to crashes, data corruption, or even exploitable vulnerabilities.

Buffer-Overflow-Vulnerabilities-KrishnaG-CEO

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

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.

Improper-Auth-KrishnaG-CEO

2024 CWE Top 25 Most Dangerous Software Weaknesses: Improper Authentication (CWE-287)

Improper Authentication occurs when a software application fails to properly verify the identity of a user or system attempting to gain access. This weakness enables unauthorised entities to bypass security measures and gain access to sensitive data or system functionalities.

Command-Injection-KrishnaG-CEO

2024 CWE Top 25 Most Dangerous Software Weaknesses: Improper Neutralisation of Special Elements used in a Command (‘Command Injection’) CWE-77

CWE-77 refers to the improper neutralisation of special elements used in a command. These special elements, when inadequately sanitised, allow attackers to inject malicious commands that the system interprets and executes. This vulnerability commonly appears in applications that dynamically construct system commands based on user inputs.
