Descriptions

A security feature bypass vulnerability exists when Microsoft Edge improperly handles requests of different origins, aka "Microsoft Edge Security Feature Bypass Vulnerability." This affects Microsoft Edge.

Existe una vulnerabilidad de omisión de la característica de seguridad cuando Microsoft Edge gestiona de manera incorrecta las peticiones de diferentes orígenes. Esto también se conoce como "Microsoft Edge Security Feature Bypass Vulnerability". Esto afecta a Microsoft Edge.

This vulnerability allows local attackers to escape the sandbox on vulnerable installations of Microsoft Edge. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists due to the fact that various operations can be triggered from within the Microsoft Edge sandbox. Considered individually, these operations do not pose a risk. However, they can be used in combination to produce an unsafe result. An attacker can leverage this in conjunction with other vulnerabilities to execute code under the context of the current user at medium integrity.
