Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) 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


2) 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.


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) Missing Encryption of Sensitive Data (CVE-ID: CVE-2022-2097)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to an error in AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimized implementation. Under specific circumstances OpenSSL does not encrypt the entire message and can reveal sixteen bytes of data that was preexisting in the memory that wasn't written. A remote attacker can gain access to potentially sensitive information.



5) 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.


6) 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.
