Description

This security bulletin contains information about 14 secuirty vulnerabilities.


1) Inefficient regular expression complexity (CVE-ID: CVE-2023-36053)

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

The vulnerability exists due to insufficient input validation when processing untrusted input with a regular expressions within EmailValidator and URLValidator. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.


2) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2023-37276)

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

The vulnerability exists due to improper validation of HTTP requests in the aiohttp.web.Application. 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) Resource exhaustion (CVE-ID: CVE-2023-41164)

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

The vulnerability exists due to application does not properly control consumption of internal resources within the django.utils.encoding.uri_to_iri() method. A remote attacker can pass a large number of characters to the affected method and perform a denial of service (DoS) attack.


4) Resource exhaustion (CVE-ID: CVE-2023-43665)

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

The vulnerability exists due to application does not properly control consumption of internal resources within the chars() and words() methods. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


5) 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.


6) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2023-49081)

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 version. 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.


7) NULL pointer dereference (CVE-ID: CVE-2023-49083)

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

The vulnerability exists due to a NULL pointer dereference error when calling the load_pem_pkcs7_certificates() or load_der_pkcs7_certificates() functions. A remote attacker can pass specially crafted PKCS7 blob/certificate certificate to the application and perform a denial of service (DoS) attack.


8) Cross-site scripting (CVE-ID: CVE-2024-22195)

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 xmlattr filter. 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.


9) 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



10) Cryptographic issues (CVE-ID: CVE-2024-23342)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to a side-channel attack on P-256. A remote attacker can launch Minerva attack and gain access to sensitive information.


11) 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.


12) Resource exhaustion (CVE-ID: CVE-2024-24680)

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

The vulnerability exists due to application does not properly control consumption of internal resources in intcomma template filter. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


13) Inefficient regular expression complexity (CVE-ID: CVE-2024-27351)

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

The vulnerability exists due to insufficient input validation when processing untrusted input with a regular expressions in django.utils.text.Truncator.words(). A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.


14) 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.
