CVE-2022-41704 : Exploit Details and Defense Strategies

Apache Batik prior to 1.16 allows RCE when loading untrusted SVG input.

Understanding CVE-2022-41704

A vulnerability in Batik of Apache XML Graphics allows an attacker to run untrusted Java code from an SVG. This issue affects Apache XML Graphics prior to 1.16. It is recommended to update to version 1.16.

What is CVE-2022-41704?

CVE-2022-41704 is a vulnerability in Apache Batik that permits Remote Code Execution (RCE) when processing malicious SVG files. By exploiting this flaw, an attacker can execute untrusted Java code, potentially leading to unauthorized access and control of the affected system.

The Impact of CVE-2022-41704

The impact of CVE-2022-41704 is severe as it allows threat actors to execute arbitrary Java code within the context of the affected application. This could result in unauthorized actions, data leakage, or complete system compromise.

Technical Details of CVE-2022-41704

Apache Batik is susceptible to an issue where a jar file can be loaded from an SVG script element, providing an avenue for attackers to execute arbitrary code.

Vulnerability Description

The vulnerability in Batik allows attackers to embed malicious Java code within SVG files, enabling the execution of arbitrary commands on the target system.
