Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Security features bypass (CVE-ID: CVE-2022-32222)

The vulnerability allows a remote attacker to bypass security restrictions

The vulnerability exists due to Node.js after start on linux based systems attempts to read /home/iojs/build/ws/out/Release/obj.target/deps/openssl/openssl.cnf, which ordinarily doesn't exist. A remote unauthenticated attacker can attemp to read openssl.cnf from /home/iojs/build/ upon startup to create this file and affect the default OpenSSL configuration for other users.


2) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2022-32214)

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

The vulnerability exists due to llhttp parser in the http module does not strictly use the CRLF sequence to delimit 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.


3) Improper Check or Handling of Exceptional Conditions (CVE-ID: CVE-2022-32212)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to IsIPAddress does not properly checks if an IP address is invalid or not. A remote unauthenticated attacker can exploit this vulnerability to bypass the IsAllowedHost check and execute arbitrary code on the system.


4) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2022-32215)

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

The vulnerability exists due to llhttp parser in the http module does not correctly handle multi-line Transfer-Encoding headers. 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) Insecure DLL loading (CVE-ID: CVE-2022-32223)

The vulnerability allows a local attacker to elevate privileges on the system

The vulnerability exists due to DLL search order hijacking of providers.dll. A local attacker can place a specially crafted .dll file and elevate privileges on the system


6) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2022-32213)

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 request to lead to HTTP Request Smuggling to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
