Multiple vulnerabilities in McAfee products

1) Cross-site scripting

EUVDB-ID: #VU12135

Risk: Low

CVSSv3.1: 4.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-6659

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

Exploit availability: No

Description

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

The weakness 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.

Mitigation

Update to versions 5.3.3 or 5.9.1.

Vulnerable software versions

2) Path traversal

EUVDB-ID: #VU12136

Risk: Low

CVSSv3.1: 5.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-6660

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Exploit availability: No

Description

The vulnerability allows an adjacent attacker to obtain potentially sensitive information on the target system.

The weakness exists due to path traversal. An adjacent attacker can export a specially crafted XML file, use Windows alternate data streams, bypass the file extensions via improper validation of the path and gain access to potentially sensitive information.

3) Insecure DLL loading

EUVDB-ID: #VU12138

Risk: Low

CVSSv3.1: 7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2018-6661

CWE-ID: CWE-427 - Uncontrolled Search Path Element

Exploit availability: Yes

Description

The vulnerability allows a local attacker to gain elevated privileges on the target system.
