Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2022-42252)

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 via an invalid Content-Length header.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks but requires Tomcat to be configured to ignore invalid HTTP headers via setting rejectIllegalHeader to false (not the default configuration).


2) Code Injection (CVE-ID: CVE-2022-45143)

The vulnerability allows a remote attacker to manipulate server output.

The vulnerability exists due to improper input validation within the JsonErrorReportValve when handling type, message or description values. A remote attacker can send a specially crafted request and manipulate or invalidate JSON output.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


3) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-24998)

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

The vulnerability exists due to Apache Commons FileUpload does not limit the number of request parts. A remote attacker can initiate a series of uploads and perform a denial of service (DoS) attack.


4) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-28709)

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

The vulnerability exists due to an incomplete fox for #VU72427 (CVE-2023-24998). If non-default HTTP connector settings were used such that the maxParameterCount could be reached using query string parameters and a request was submitted that supplied exactly maxParameterCount parameters in the query string, the limit for uploaded request parts could be bypassed. A remote attacker can initiate a series of uploads and perform a denial of service (DoS) attack.
