CVE-2023-32699 : Exploit Details and Defense Strategies

This article provides detailed information on the MeterSphere denial of service vulnerability identified as CVE-2023-32699.

Understanding CVE-2023-32699

CVE-2023-32699 is a denial of service vulnerability in MeterSphere, an open-source continuous testing platform. The vulnerability exists in versions prior to 2.10.0, allowing an attacker to trigger a denial of service attack on the server.

What is CVE-2023-32699?

The vulnerability is caused by the inefficiency in processing long passwords during the login process. By submitting an excessively long password, an attacker can exhaust the server CPU and memory resources, leading to a denial of service condition.

The Impact of CVE-2023-32699

The impact of CVE-2023-32699 is significant as it allows attackers to disrupt the availability of MeterSphere services, potentially leading to service downtime and unavailability.

Technical Details of CVE-2023-32699

CVE-2023-32699 revolves around a denial of service vulnerability triggered by the inefficient handling of long passwords.

Vulnerability Description

MeterSphere versions prior to 2.10.0 are vulnerable due to the

checkUserPassword

method's inefficiency in processing long passwords, leading to server exhaustion.

Affected Systems and Versions

The vulnerability affects MeterSphere versions earlier than 2.10.0, with version 2.9.1 and prior considered vulnerable to the denial of service attack.

Exploitation Mechanism

Attackers exploit the vulnerability by submitting abnormally long passwords during the login process, causing the server to consume excessive CPU and memory resources, ultimately leading to a denial of service.

Mitigation and Prevention

To mitigate the CVE-2023-32699 vulnerability and prevent potential attacks, consider the following steps:

Immediate Steps to Take

Upgrade MeterSphere to version 2.10.0 or later to eliminate the denial of service vulnerability.
Monitor system performance for any signs of unusual resource consumption that could indicate a denial of service attack.

Long-Term Security Practices

Implement password length restrictions to prevent excessively long passwords from being submitted.
Regularly update MeterSphere to ensure that the latest security patches and improvements are applied.

Patching and Updates

Ensure your MeterSphere installation is always up to date with the latest patches and security updates to protect against known vulnerabilities.
