Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


7) Information disclosure (CVE-ID: CVE-2018-8289)

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The vulnerability exists due to an error when Microsoft Edge improperly handles objects in memory. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website and gain access to arbitrary data.


8) Information disclosure (CVE-ID: CVE-2018-8324)

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The vulnerability exists due to an error when Microsoft Edge improperly handles objects in memory. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website and gain access to arbitrary data.


9) Information disclosure (CVE-ID: CVE-2018-8325)

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The vulnerability exists due to an error when Microsoft Edge improperly handles objects in memory. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website and gain access to arbitrary data.


10) Cross-site scripting (CVE-ID: CVE-2018-8278)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.


11) Information disclosure (CVE-ID: CVE-2018-8297)
