CVE-2024-32653 in jadx
Summary
by MITRE • 04/23/2024
jadx is a Dex to Java decompiler. Prior to version 1.5.0, the package name is not filtered before concatenation. This can be exploited to inject arbitrary code into the package name. The vulnerability allows an attacker to execute commands with shell privileges. Version 1.5.0 contains a patch for the vulnerability.

The vulnerability identified as CVE-2024-32653 affects jadx, a popular decompiler tool that translates android dex bytecode into readable java source code. This tool serves as an essential component in reverse engineering android applications and is widely used by security researchers, developers, and penetration testers. The vulnerability stems from inadequate input validation within the package name handling mechanism of the decompiler, creating a critical security flaw that can be exploited to execute arbitrary code with elevated privileges.
The technical flaw manifests in the improper filtering of package names before concatenation operations within the jadx application. When processing dex files, the decompiler constructs package names by directly concatenating user-supplied input without adequate sanitization or validation. This allows an attacker to craft malicious package names containing shell metacharacters or command injection sequences that get executed during the decompilation process. The vulnerability specifically affects versions prior to 1.5.0 where the developers failed to implement proper input sanitization measures for package name handling, creating a path for command injection attacks.
The operational impact of this vulnerability is severe as it provides attackers with the ability to execute arbitrary commands with shell privileges when the vulnerable jadx version processes malicious dex files. An attacker could craft a specially designed android application package with malicious package names that, when decompiled using the vulnerable version of jadx, would trigger command execution on the system where the decompiler is running. This could lead to complete system compromise, data exfiltration, or further lateral movement within a network environment where the decompiler is used for analysis.
This vulnerability maps to CWE-78, which specifically addresses OS Command Injection, and aligns with ATT&CK technique T1059.007 for command and scripting interpreter. The attack surface is particularly concerning for security professionals who use jadx as part of their analysis workflow, as simply opening a malicious dex file could result in unauthorized code execution. The patch implemented in version 1.5.0 addresses the root cause by introducing proper input validation and sanitization of package names before any concatenation or processing occurs, effectively neutralizing the command injection vector.
Organizations and individuals using jadx should immediately upgrade to version 1.5.0 or later to mitigate this vulnerability. Security teams should also implement monitoring for unusual command execution patterns when using jadx, particularly when processing untrusted dex files from external sources. Additionally, defensive measures such as sandboxed execution environments for decompilation activities and regular security assessments of development tools can help reduce the risk of exploitation in environments where legacy versions might still be in use. The vulnerability underscores the importance of proper input validation in all software components, especially those handling user-supplied data in security-sensitive applications.
