Why are business logic vulnerabilities challenging to detect?

Unlike known vulnerabilities, they don’t arise from traditional security flaws such as XSS or SQL injection; instead, these vulnerabilities involve exploiting the way applications are designed. So, these vulnerabilities arise because of wrong assumptions about user behavior and design flaws. Consequently, they aren’t easy to detect as context-specific issues are hard to identify.

What are the impacts of business logic vulnerabilities on web apps?

BLVs exploit the intended functionality of a web application and have serious security consequences such as: Financial loss, Data integrity, Abuse and fraud, Operational disruptions, Reputation damage.

How are business logic vulnerabilities different from common vulnerabilities?

Business logic vulnerabilities arise due to the exploitation of flaws in application design and intended workflow instead of traditional technical coding issues. Traditional vulnerability occurs due to technical issues like poor authentication controls, and BLVs occur due to the unintended use of legitimate features.
