Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Cross-site scripting

EUVDB-ID: #VU27052

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2020-11022

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

Exploit availability: Yes

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 in the regex operation in "jQuery.htmlPrefilter". A remote attacker can pass specially crafted data to the application that uses .html()</code>, <code>.append() or similar methods for it and execute arbitrary JavaScript 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 update from vendor's website.

Exploit availability: Yes

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 when passing <option> elements to jQuery’s DOM manipulation methods. A remote attacker can execute arbitrary JavaScript code in user's browser in context of vulnerable website.

EUVDB-ID: #VU18092

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2019-11358

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: Yes

Description

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

The vulnerability exists due to prototype pollution. A remote attacker can trick the extend function can into modifying the prototype of Object when the attacker controls part of the structure passed to this function. This can let an attacker add or modify an existing property that will then exist on all objects and perform a denial of service (DoS) attack.

Mitigation

Install update from vendor's website.
