This CVE record was published on January 30, 2023, by MITRE. The vulnerability identified as CVE-2023-24622 exists in the

isInList

function within the safeurl-python package before version 1.2 for Python. The issue arises due to an insufficiently restrictive regular expression for external domains, potentially leading to Server-Side Request Forgery (SSRF) attacks.

Understanding CVE-2023-24622

The CVE-2023-24622 focuses on a specific vulnerability within the safeurl-python package that can be exploited for SSRF attacks if not mitigated.

What is CVE-2023-24622?

CVE-2023-24622 refers to a security vulnerability in the

isInList

function of the safeurl-python package before version 1.2. This flaw allows attackers to control the URL being validated, potentially leading to SSRF risks.

The Impact of CVE-2023-24622

The impact of CVE-2023-24622 can be significant as it opens up the possibility for malicious actors to manipulate URLs, tricking the application into interacting with unintended external systems. This can have serious consequences, including unauthorized data access or service disruption.

Technical Details of CVE-2023-24622

Understanding the technical aspects of CVE-2023-24622 is crucial for implementing effective mitigation strategies.

Vulnerability Description

The vulnerability in the

isInList

function of the safeurl-python package arises from the use of an overly permissive regular expression for external domains. This allows attackers to specify arbitrary URLs, potentially leading to SSRF attacks.

Affected Systems and Versions

All versions of the safeurl-python package before 1.2 for Python are affected by CVE-2023-24622. Users of these versions are at risk of exploitation if the vulnerability is not addressed.

Exploitation Mechanism

Attackers can exploit this vulnerability by providing malicious URLs that bypass the intended validation checks in the

isInList

function. This could result in the application making unauthorized requests to internal systems or services.

Mitigation and Prevention

Taking proactive measures to mitigate the risks associated with CVE-2023-24622 is essential to safeguard systems and data.

Immediate Steps to Take

It is recommended to update the safeurl-python package to version 1.2 or later, where the vulnerability has been patched. This will help prevent exploitation of the SSRF vulnerability in the

isInList

function.

Long-Term Security Practices

Implementing secure URL validation mechanisms and regularly updating third-party packages can help prevent similar vulnerabilities in the future. Conducting security reviews and audits of code that interacts with external resources is also advisable.

Patching and Updates

Stay informed about security advisories and updates for the safeurl-python package to ensure that known vulnerabilities are promptly addressed. Regularly monitor for new patches and apply them as soon as they are available to maintain a secure environment.
