CVE-2023-24816 Explained : Impact and Mitigation

This CVE identifier refers to a vulnerability found in IPython (Interactive Python) that exposes systems to the risk of command injection through the

set_term_title

function.

Understanding CVE-2023-24816

This vulnerability, identified as a command injection flaw, affects IPython versions prior to 8.1.0. It involves a specific set of conditions that need to be met for exploitation.

What is CVE-2023-24816?

IPython is a command shell designed for interactive computing in various programming languages, primarily meant for Python. The vulnerability arises when the

set_term_title

function is utilized on Windows within a Python environment lacking the

ctypes

module. This condition can allow an attacker to inject malicious shell commands, limited to the current process's scope.

The Impact of CVE-2023-24816

The impact of this vulnerability is rated as medium severity. Although the exploitation requires specific circumstances to be met, successful attacks can result in the execution of unauthorized commands within the context of the affected process.

Technical Details of CVE-2023-24816

This section delves into specific technical aspects of the CVE, shedding light on the vulnerability's description, affected systems and versions, as well as the exploitation mechanism.

Vulnerability Description

The vulnerability in IPython stems from improper input validation, enabling malicious actors to inject OS commands through the

set_term_title

function in certain scenarios. This can lead to the unauthorized execution of commands within the affected process.

Affected Systems and Versions

IPython versions prior to 8.1.0 are impacted by this vulnerability. Users utilizing IPython as a library and making calls to the

set_term_title

function should be cautious to avoid untrusted input that could be exploited by attackers.

Exploitation Mechanism

The exploitation of CVE-2023-24816 involves leveraging the lack of the

ctypes

module in a Python environment and executing malicious commands through the vulnerable function. To mitigate this risk, users are advised to upgrade to versions beyond 8.1.0 or ensure that any input passed to

IPython.utils.terminal.set_term_title

is carefully validated.

Mitigation and Prevention

Incorporating effective mitigation strategies and preventive measures is crucial to safeguard systems against potential threats posed by CVE-2023-24816.

Immediate Steps to Take

Users should upgrade IPython to versions 8.1.0 or above to mitigate the vulnerability.
Exercise caution when handling untrusted inputs within functions like

set_term_title

.

Long-Term Security Practices

Ensure regular monitoring and updating of software dependencies to mitigate potential vulnerabilities proactively.
Implement secure coding practices to prevent command injection and other types of security vulnerabilities.

Patching and Updates

Stay informed about security advisories and patches released by IPython to address known vulnerabilities promptly.
Regularly update IPython and associated libraries to benefit from security fixes and improvements.
