Overview

Affected versions of this package are vulnerable to XML External Entity (XXE) Injection via the toXmlDocument function of XmlStringPrettyFormatter. An attacker can read arbitrary local files, perform server-side request forgery, or cause denial of service by providing crafted XML input containing external entities.

Note: This formatter is used by isXmlEqualTo(CharSequence) and xmlPrettyFormat(String) and could be exploited if untrusted XML input is processed by the methods.

Workaround

Replace use of isXmlEqualTo(CharSequence) with XMLUnit.

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.assertj:assertj-core to version 3.27.7 or higher.

Arbitrary Code Execution

    Remediation: Upgrade to org.apache.logging.log4j:log4j-slf4j-impl@2.17.1.

Overview

org.apache.logging.log4j:log4j-core is a logging library for Java.

Affected versions of this package are vulnerable to Arbitrary Code Execution.
Note: Even though this vulnerability appears to be related to the log4Shell vulnerability, this vulnerability requires an attacker to have access to modify configurations to be exploitable, which is rarely possible.

An attacker with access to modification of logging configuration is able to configure JDBCAppender with a data source referencing a JNDI URI - which can execute malicious code.

In the fixed versions, JDBCAppender is using JndiManager and disables JNDI lookups by default (via log4j2.enableJndiJdbc=false).

Alternative Remediation

If you have reason to believe your application may be vulnerable and upgrading is not an option, you can either:

  • Disable/remove JDBCAppender
  • If JDBCAppender is used, make sure that it is not configured to use any protocol other than Java

Remediation

Upgrade org.apache.logging.log4j:log4j-core to version 2.3.2, 2.12.4, 2.17.1 or higher.

Improper Validation of Certificate with Host Mismatch

  • Vulnerable module: org.apache.logging.log4j:log4j-core

    Remediation: Upgrade to org.apache.logging.log4j:log4j-slf4j-impl@2.25.3.

Overview

org.apache.logging.log4j:log4j-core is a logging library for Java.

Affected versions of this package are vulnerable to Improper Validation of Certificate with Host Mismatch due to the lack of TLS hostname verification in the SocketAppender component. An attacker can intercept or redirect log traffic by performing a man-in-the-middle attack if they are able to intercept or redirect network traffic between the client and the log receiver and can present a server certificate issued by a certification authority trusted by the configured trust store or the default Java trust store.

Workaround

This vulnerability can be mitigated by configuring the SocketAppender to use a private or restricted trust root to limit the set of trusted certificates.

Remediation

Upgrade org.apache.logging.log4j:log4j-core to version 2.25.3 or higher.

Overview

junit:junit is an unit testing framework for Java

Affected versions of this package are vulnerable to Information Exposure. The JUnit4 test rule TemporaryFolder contains a local information disclosure vulnerability. On Unix like systems, the system's temporary directory is shared between all users on that system. Because of this, when files and directories are written into this directory they are, by default, readable by other users on that same system.

Note: This vulnerability does not allow other users to overwrite the contents of these directories or files. This only affects Unix like systems.

Remediation

Upgrade junit:junit to version 4.13.1 or higher.
