Security Bulletin

This security bulletin contains information about 10 vulnerabilities.

1) Cross-site scripting

EUVDB-ID: #VU17160

Risk: Low

CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-6228

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Exploit availability: No

Description

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

The vulnerability exists in the Safari Reader component 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 the authentication cookies and gain access to the device.

Mitigation

Update to version 12.0.3.

Vulnerable software versions

Apple Safari: 12.0 - 12.0.2
