Overview

org.apache.tomcat.embed:tomcat-embed-core is a Core Tomcat implementation.

Affected versions of this package are vulnerable to Denial of Service (DoS) when processing a crafted HTTP/2 request. If the request exceeded any of the configured limits for headers, the associated HTTP/2 stream was not reset until after all of the headers had been processed.

Details

Denial of Service (DoS) describes a family of attacks, all aimed at making a system inaccessible to its intended and legitimate users.

Unlike other vulnerabilities, DoS attacks usually do not aim at breaching security. Rather, they are focused on making websites and services unavailable to genuine users resulting in downtime.

One popular Denial of Service vulnerability is DDoS (a Distributed Denial of Service), an attack that attempts to clog network pipes to the system by generating a large volume of traffic from many machines.

When it comes to open source libraries, DoS vulnerabilities allow attackers to trigger such a crash or crippling of the service by using a flaw either in the application code or from the use of open source libraries.

Two common types of DoS vulnerabilities:

• High CPU/Memory Consumption- An attacker sending crafted requests that could cause the system to take a disproportionate amount of time to process. For example, commons-fileupload:commons-fileupload.

• Crash - An attacker sending crafted requests that could cause the system to crash. For Example, npm ws package

Remediation

Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 8.5.99, 9.0.86, 10.1.19, 1.0.0-M17 or higher.

Overview

Affected versions of this package are vulnerable to Denial of Service (DoS) when a WebSocket client can keep a WebSocket connection open which is leading to increased resource consumption.

Overview

org.springframework:spring-core is a core package within the spring-framework that contains multiple classes and utilities.

Affected versions of this package are vulnerable to Uncontrolled Resource Consumption ('Resource Exhaustion') via specially crafted HTTP requests. An attacker can cause a denial-of-service condition by sending malicious requests that exploit this issue.

Notes:

This is only exploitable if the application uses Spring MVC and Spring Security 6.1.6+ or 6.2.1+ is on the classpath.

Typically, Spring Boot applications need the org.springframework.boot:spring-boot-starter-web and org.springframework.boot:spring-boot-starter-security dependencies to meet all conditions.

Remediation

Upgrade org.springframework:spring-core to version 6.0.16, 6.1.3 or higher.

Overview

org.springframework:spring-web is a package that provides a comprehensive programming and configuration model for modern Java-based enterprise applications - on any kind of deployment platform.

Affected versions of this package are vulnerable to Open Redirect when UriComponentsBuilder parses an externally provided URL, and the application subsequently uses that URL. If it contains hierarchical components such as path, query, and fragment it may evade validation.

Remediation

Upgrade org.springframework:spring-web to version 5.3.32, 6.0.17, 6.1.4 or higher.

Overview

org.springframework:spring-web is a package that provides a comprehensive programming and configuration model for modern Java-based enterprise applications - on any kind of deployment platform.

Affected versions of this package are vulnerable to Open Redirect when using UriComponentsBuilder to parse an externally provided URL and perform validation checks on the host of the parsed URL.

Note: This is the same as CVE-2024-22243, but with different input.

Remediation

Upgrade org.springframework:spring-web to version 5.3.33, 6.0.18, 6.1.5 or higher.
