CVE-2023-26145 : What You Need to Know

This CVE, assigned by Snyk, was published on September 28, 2023. It has a base severity rating of HIGH with a CVSS score of 7.4. The vulnerability is related to Command Injection in the package pydash before version 6.0.0, impacting certain methods within the package.

Understanding CVE-2023-26145

This section will delve into the details of CVE-2023-26145, focusing on what the vulnerability entails and its possible impact.

What is CVE-2023-26145?

The CVE-2023-26145 vulnerability affects versions of the package pydash before 6.0.0. Specifically, it involves certain pydash methods that accept dotted paths (Deep Path Strings) to target a nested Python object, relative to the original source object. These paths can be used by attackers to target internal class attributes and dict items within nested Python objects.

The Impact of CVE-2023-26145

The impact of this vulnerability is significant, with a HIGH confidentiality and integrity impact. Attackers exploiting this vulnerability have the potential to retrieve, modify, or invoke nested Python objects using the vulnerable pydash methods.

Technical Details of CVE-2023-26145

In this section, we will explore the technical aspects of CVE-2023-26145, including a description of the vulnerability, affected systems and versions, and the exploitation mechanism.

Vulnerability Description

The vulnerability in pydash arises from the pydash.objects.invoke() and pydash.collections.invoke_map() methods. These methods are susceptible to Command Injection when specific conditions are met, allowing attackers to execute arbitrary commands by manipulating the source object and path string arguments.

Affected Systems and Versions

The vulnerability impacts versions of the pydash package prior to 6.0.0. Systems using pydash with versions less than 6.0.0 are considered affected and vulnerable to Command Injection.

Exploitation Mechanism

To exploit the vulnerability, attackers need to meet certain prerequisites such as controlling the path string and arguments passed to the invoked method. By targeting the vulnerable pydash methods, attackers can execute unauthorized commands within the Python environment.

Mitigation and Prevention

In order to address CVE-2023-26145 and enhance overall security posture, it is crucial to implement both immediate steps and long-term security practices. Patching and updating affected systems are essential to mitigate the risks associated with this vulnerability.

Immediate Steps to Take

Update pydash to version 6.0.0 or newer to prevent exploitation of the Command Injection vulnerability.
Avoid passing user-controlled input directly to the vulnerable pydash methods to minimize the risk of unauthorized command execution.

Long-Term Security Practices

Regularly monitor security advisories and updates for the pydash package to stay informed about potential vulnerabilities.
Implement input validation and sanitization techniques to prevent untrusted data from being processed by vulnerable methods.

Patching and Updates

Refer to the provided references to access the necessary patches and updates for the pydash package. Stay proactive in applying patches promptly to protect systems from known vulnerabilities.
