2) Inconsistent interpretation of HTTP requests

EUVDB-ID: #VU26355

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-10108

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to an error when processing two Content-length headers, sent within one HTTP request that caused the request body to be interpreted as a pipelined request. A remote attacker can send a specially crafted HTTP request to the affected web server and posing HTTP cache or perform other attacks against web application.

Mitigation

Update the affected package python-Twisted to the latest version.

3) Origin validation error

EUVDB-ID: #VU61611

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-21712

CWE-ID: CWE-346 - Origin Validation Error

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to origin validation error in the "twited.web.RedirectAgent" and "twisted.web.BrowserLikeRedirectAgent" functions. A remote attacker attacker can trick the victim to click on a specially crafted link and obtain cookies and authorization headers.

Mitigation

Update the affected package python-Twisted to the latest version.

4) Cross-site scripting

EUVDB-ID: #VU68855

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-2022-39348

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 datawithin "NameVirtualHost". A remote user 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 the affected package python-Twisted to the latest version.
