Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Use-after-free (CVE-ID: CVE-2021-22930)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing HTTP/2 stream canceling requests. A remote attacker can send a specially crafted HTTP/2 request, trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


2) Improper input validation (CVE-ID: CVE-2021-22931)

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The vulnerability exists due to improper input validation within the Cluster: General (Node.js) component in MySQL Cluster. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.


3) Use-after-free (CVE-ID: CVE-2021-22940)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error. A remote attacker can change process behavior.


4) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2021-22960)

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

The vulnerability exists due to improper validation of HTTP requests, where the application ignores chunk extensions when parsing the body of chunked 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) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2021-22959)

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

The vulnerability exists due to improper validation of HTTP requests, where the application accepts requests with a space right after the header name before the colon. 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.
