CVE-2023-28862 : Vulnerability Insights and Analysis

This article provides a detailed overview of CVE-2023-28862, highlighting the key aspects of the vulnerability, its impact, technical details, and mitigation strategies.

Understanding CVE-2023-28862

CVE-2023-28862 is a recently published CVE entry that identifies a security issue in LemonLDAP::NG before version 2.16.1. The vulnerability involves weak session ID generation in the AuthBasic handler and incorrect failure handling during a password check, potentially enabling attackers to bypass two-factor authentication (2FA) verification.

What is CVE-2023-28862?

The CVE-2023-28862 vulnerability allows malicious actors to circumvent 2FA verification by exploiting weaknesses in session ID generation and password check failure handling within the LemonLDAP::NG software before version 2.16.1. This could lead to unauthorized access to sensitive information and systems.

The Impact of CVE-2023-28862

The impact of CVE-2023-28862 is significant as it exposes systems using LemonLDAP::NG prior to version 2.16.1 to potential security breaches. Attackers could exploit this vulnerability to bypass 2FA mechanisms, compromising the confidentiality and integrity of user data and organizational resources.

Technical Details of CVE-2023-28862

The technical details of CVE-2023-28862 shed light on the vulnerability itself, the affected systems and versions, as well as the exploitation mechanism.

Vulnerability Description
