CVE-2019-1054

Status: ModifiedMedium (5)—

A security feature bypass vulnerability exists in Edge that allows for bypassing Mark of the Web Tagging (MOTW). Failing to set the MOTW means that a large number of Microsoft security technologies are bypassed. In a web-based attack scenario, an attacker could host a malicious website that is designed to exploit the security feature bypass. Alternatively, in an email or instant message attack scenario, the attacker could send the targeted user a specially crafted .url file that is designed to exploit the bypass.

Additionally, compromised websites or websites that accept or host user-provided content could contain specially crafted content to exploit the security feature bypass. However, in all cases an attacker would have no way to force a user to view attacker-controlled content. Instead, an attacker would have to convince a user to take action. For example, an attacker could entice a user to either click a link that directs the user to the attacker's site or send a malicious attachment. The security update addresses the security feature bypass by correcting how Edge handles MOTW tagging.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
