Security Advisory

1) Origin validation error

Severity: Medium

CVSSv3: 4.7 [CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C] [PCI]

CVE-ID: CVE-2020-3864

CWE-ID: CWE-346 - Origin Validation Error

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to an logical error that leads to DOM object not having a unique security origin. A remote attacker can interact with DOM objects from another domain.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

WebKitGTK+: 2.26.1, 2.26.2, 2.26.3

WPE WebKit: 2.26.0, 2.26.1, 2.26.2, 2.26.3

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Buffer overflow

Severity: Low

CVSSv3: 3.8 [CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-3862

CWE-ID: CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error. A remote attacker can create a specially crafted web page, trick the victim into visiting it and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

WebKitGTK+: 2.26.1, 2.26.2, 2.26.3

WPE WebKit: 2.26.0, 2.26.1, 2.26.2, 2.26.3

3) Origin validation error

Severity: Medium

CVSSv3: 4.7 [CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C] [PCI]

CVE-ID: CVE-2020-3865

CWE-ID: CWE-346 - Origin Validation Error

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to a logical error that leads to a top-level DOM object context being incorrectly considered secure. A remote attacker can gain unauthorized access to DOM objects from another domain.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

WebKitGTK+: 2.26.1, 2.26.2, 2.26.3

WPE WebKit: 2.26.0, 2.26.1, 2.26.2, 2.26.3

4) Univeral cross-site scripting

Severity: Medium

CVSSv3: 5.3 [CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C] [PCI]

CVE-ID: CVE-2020-3867

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 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

Install updates from vendor's website.

5) Buffer overflow

Severity: High

CVSSv3: 7.7 [CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C] [PCI]

CVE-ID: CVE-2020-3868

CWE-ID: CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing HTML content. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.

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

Mitigation

Install updates from vendor's website.
