This security bulletin contains information about 2 vulnerabilities.

1) Inconsistent interpretation of HTTP requests

EUVDB-ID: #VU62077

Risk: Medium

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-2022-24801

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

Exploit availability: No

Description

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

The vulnerability exists due to improper validation of HTTP requests within the twisted.web.http module. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.

Mitigation

Update the affected packages:

i686:
    python26-twisted-web-8.2.0-6.8.amzn1.i686
    python27-twisted-web-8.2.0-6.8.amzn1.i686

src:
    python-twisted-web-8.2.0-6.8.amzn1.src

x86_64:
    python26-twisted-web-8.2.0-6.8.amzn1.x86_64
    python27-twisted-web-8.2.0-6.8.amzn1.x86_64

2) 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 packages:

i686:
    python26-twisted-web-8.2.0-6.8.amzn1.i686
