Overview

net.minidev:json-smart is a Java JSON parser.

Affected versions of this package are vulnerable to Denial of Service (DoS). An attacker can cause a stack exhaustion and subsequent service disruption by providing JSON input with an excessive number of nested {.

Note:

This issue exists because of an incomplete fix for CVE-2023-1370.

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 net.minidev:json-smart to version 2.5.2 or higher.

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 Incorrect Authorization via the AnnotationsScanner and AnnotatedMethod class. An attacker can gain unauthorized access to sensitive information by exploiting improper resolution of annotations on methods within type hierarchies that use parameterized supertypes with unbounded generics.

Note: This is only exploitable if security annotations are used on methods in generic superclasses or generic interfaces and the @EnableMethodSecurity feature is enabled.

Remediation

Upgrade org.springframework:spring-core to version 6.2.11 or higher.

Overview

org.springframework:spring-beans is a package that is the basis for Spring Framework's IoC container. The BeanFactory interface provides an advanced configuration mechanism capable of managing any type of object.

Affected versions of this package are vulnerable to Relative Path Traversal when deployed on non-compliant Servlet containers. An unauthenticated attacker could gain access to files and directories outside the intended web root.

Notes:

1. This is only exploitable if the application is deployed as a WAR or with an embedded Servlet container, the Servlet container does not reject suspicious sequences and the application serves static resources with Spring resource handling.

2. Applications deployed on Apache Tomcat or Eclipse Jetty are not vulnerable, as long as default security features are not disabled in the configuration.

3. This vulnerability was also fixed in the commercial versions 6.1.22 and 5.3.44.

Remediation

Upgrade org.springframework:spring-beans to version 6.2.10 or higher.
