CVE-2022-36042 : Vulnerability Insights and Analysis

Rizin Out-of-bounds Write vulnerability in dyld cache binary plugin.

Understanding CVE-2022-36042

Rizin is a UNIX-like reverse engineering framework and command-line toolset. The vulnerability exists in versions 0.4.0 and prior, where an out-of-bounds write vulnerability occurs when accessing data from dyld cache files. This security flaw could be exploited by an attacker to execute arbitrary code on the target system.

What is CVE-2022-36042?

The CVE-2022-36042 vulnerability is a critical out-of-bounds write security issue in the dyld cache binary plugin within Rizin version 0.4.0 and earlier. Opening a malicious dyld cache file could trigger the vulnerability, leading to potential code execution by malicious actors.

The Impact of CVE-2022-36042

The impact of CVE-2022-36042 is significant as it allows threat actors to execute code on a victim's machine by exploiting the out-of-bounds write vulnerability in dyld cache files. This could result in unauthorized access, data theft, or further compromise of the affected system.

Technical Details of CVE-2022-36042

The following technical details outline the vulnerability, affected systems, and exploitation mechanisms:

Vulnerability Description

The vulnerability in the dyld cache binary plugin in Rizin <= 0.4.0 allows attackers to perform out-of-bounds writes, potentially leading to remote code execution on the victim's machine.

Affected Systems and Versions

Vendor: rizinorg
Product: rizin
Affected Versions: <= 0.4.0

Exploitation Mechanism

Exploitation of this vulnerability involves a malicious actor crafting a specific dyld cache file and tricking a user into opening it. Once the file is accessed, the attacker can execute arbitrary code on the target system.

Mitigation and Prevention

To safeguard systems against CVE-2022-36042, users and administrators should take immediate and long-term security measures, including patching and updates:

Immediate Steps to Take

Update Rizin to a non-vulnerable version above 0.4.0.
Avoid opening untrusted dyld cache files or files from unknown sources.

Long-Term Security Practices

Regularly update software and apply security patches.
Implement proper access controls and user permissions to mitigate the impact of potential exploits.

Patching and Updates

Ensure that systems are updated with the latest patches and versions of Rizin to prevent exploitation of the out-of-bounds write vulnerability.
