Ensuring Trust Through Correct Authorisation: A Comprehensive Examination of CWE-863

by

CWE-863: Incorrect Authorisation occurs when an application fails to enforce correct authorisation measures, allowing unauthorised users or processes to access resources, perform operations, or retrieve data that should be off-limits. It is sometimes conflated with authentication flaws, but the essence of CWE-863 lies in improper or missing checks that would otherwise confirm if a user has the necessary permissions to perform a specific action.
From a technical standpoint, one might imagine an application employing robust identity verification (authentication) only to overlook critical checks about what a user is allowed to do once logged in (authorisation). This oversight can be the gateway to data leaks, privilege escalation, or even sabotage of core business processes.

2024 CWE Top 25 Most Dangerous Software Weaknesses: Deserialisation of Untrusted Data (CWE-502)

by

Deserialisation refers to the process of converting serialised data (a compact format of an object or data structure) back into its original form. While this operation is indispensable in modern software, it becomes a vulnerability when the deserialised data originates from an untrusted source.
When untrusted data is deserialised without validation, attackers can exploit the process to execute arbitrary code, manipulate application logic, or inject malicious payloads. CWE-502 encapsulates this weakness, highlighting its potential to compromise data integrity, confidentiality, and availability.

Improper-Input-Validation-KrishnaG-CEO

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.
