SB2025030767 - openEuler 20.03 LTS SP4 update for python-aiohttp

Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2023-47627)

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

The vulnerability exists due to improper validation of HTTP requests when AIOHTTP_NO_EXTENSIONS is enabled. 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.

2) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2023-49082)

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

The vulnerability exists due to improper validation of HTTP requests when processing HTTP request method. 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.

3) Path traversal (CVE-ID: CVE-2024-23334)

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences in aiohttp.web.static(follow_symlinks=True). A remote attacker can send a specially crafted HTTP request and read arbitrary files on the system.

Request examples:

For windows: /static/../D:\flag.txt Poc

For Linux: /static/../../../../etc/passwd

4) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2024-23829)

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

The vulnerability exists due to improper validation of HTTP requests. 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.

5) Cross-site scripting (CVE-ID: CVE-2024-27306)

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 within the web.static(..., show_index=True) method in index pages for static file handling. A remote attacker can inject 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.

6) Infinite loop (CVE-ID: CVE-2024-30251)

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

The vulnerability exists due to infinite loop. A remote attacker can send a specially crafted POST request, consume all available system resources and cause denial of service conditions.
