1) Input validation error (CVE-ID: CVE-2021-3807)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input when matching crafted invalid ANSI escape codes in ansi-regex. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
2) 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.
3) 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.
4) 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.
5) 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.
6) Open redirect (CVE-ID: CVE-2022-33987)
The vulnerability allows a remote attacker to redirect victims to arbitrary URL.
The vulnerability exists due to requested URLs are not verified and allow open redirection to a local UNIX socket. A remote attacker can create a link that leads to a trusted website, however, when clicked, redirects the victim to arbitrary domain.
Successful exploitation of this vulnerability may allow a remote attacker to perform a phishing attack and steal potentially sensitive information.
