Vulnerability Chaining
A security concept in which multiple individually limited vulnerabilities are combined to form a complete attack path. By exploiting the dependencies among the constituent vulnerabilities, an attacker can achieve effects that no single vulnerability could produce alone.
Timeline (last 90 days)
An exploit chain refers to an attacker combining and exploiting two or more independent vulnerabilities in a specific order, such that the output of the former vulnerability becomes the input or stepping stone for the latter.
When assessed individually, each link in an exploit chain may only have capabilities such as information disclosure, limited file reading, or low-privilege object injection, and its rating often remains at medium-low severity; but when chained together, they can progressively cross the trust boundaries between the application layer, the runtime layer and the operating system layer.
During single-point scanning, security teams may rate each vulnerability in an exploit chain as medium or even low severity, thereby underestimating the overall risk.
Building an exploit chain depends on in-depth reconnaissance of the target environment, and the attacker needs to confirm conditions such as versions, configurations, writable paths and available functions.
A vulnerability chain refers to the process in which an attacker strings together multiple low- or medium-risk issues to gradually escalate privileges or expand impact and ultimately achieve a high-risk objective.
