Information disclosure vulnerabilities

Summary: PortSwigger's research explains that information disclosure, also called information leakage, occurs when a website unintentionally reveals sensitive information to its users, and that attackers often have to elicit the leak by interacting with the site in unexpected or malicious ways. The write-up separates direct impact, such as an online shop leaking customers' credit card details, from indirect impact, such as exposing directory structure or third-party framework versions that can serve as a starting point for other exploits.

Bottom line: Leaked technical detail is only as dangerous as what it unlocks: knowing a framework version is of limited use if it is fully patched, but against an old version with a known vulnerability, a devastating attack can be as simple as applying a publicly documented exploit.
