How to Fix CVE-2022-24198

To remediate this vulnerability, upgrade all affected Itext7 core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

com.itextpdf:itext7-core fixed: 7.2.0 
<dependency>
    <groupId>com.itextpdf</groupId>
    <artifactId>itext7-core</artifactId>
    <version>7.2.0</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=com.itextpdf

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-24198, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.itextpdf

Analyze the terminal output to locate any version of Itext7 core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 7.2.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.itextpdf command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-125: Out-of-bounds Read, where the product reads data past the end, or before the beginning, of the intended buffer. In Itext7 core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

iText v7.1.17 was discovered to contain an out-of-bounds exception via the component ARCFOUREncryption.encryptARCFOUR, which allows attackers to cause a Denial of Service (DoS) via a crafted PDF file. NOTE: Vendor does not view this as a vulnerability and has not found it to be exploitable.
