CVE-2023-22799 : Exploit Details and Defense Strategies

This CVE record was published on February 9, 2023, by HackerOne. It highlights a ReDoS-based DoS vulnerability in the GlobalID <1.0.1, where an attacker supplying a carefully crafted input can cause the regular expression engine to take an unexpected amount of time. Users running an affected release are advised to upgrade or implement workarounds immediately.

Understanding CVE-2023-22799

This section delves into the details of CVE-2023-22799, shedding light on the vulnerability's impact and technical aspects.

What is CVE-2023-22799?

CVE-2023-22799 is a Denial of Service vulnerability (CWE-400) that stems from a ReDoS-based DoS issue in GlobalID <1.0.1. This vulnerability allows attackers to manipulate input that significantly delays the regular expression engine's processing time, leading to a denial of service.

The Impact of CVE-2023-22799

The impact of this vulnerability is severe as it can be exploited by malicious actors to disrupt the availability of affected systems running GlobalID <1.0.1. This could result in service interruptions, slowdowns, or even system crashes, posing a considerable risk to organizations using the vulnerable software.

Technical Details of CVE-2023-22799

Under this section, we will explore the technical specifics of CVE-2023-22799, including the vulnerability description, affected systems and versions, and the exploitation mechanism.

Vulnerability Description

The vulnerability in GlobalID <1.0.1 allows attackers to launch a ReDoS-based DoS attack by supplying specially crafted input, causing the regular expression engine to consume excessive processing time. This can lead to the system becoming unresponsive or crashing.

Affected Systems and Versions

The affected product in this CVE is GlobalID <1.0.1. Users running this specific version of GlobalID are susceptible to the ReDoS-based DoS vulnerability outlined in CVE-2023-22799.

Exploitation Mechanism

Attackers can exploit CVE-2023-22799 by submitting malicious input that triggers the ReDoS behavior in the regular expression engine of GlobalID <1.0.1. This manipulation causes excessive computation, resulting in a denial of service condition.

Mitigation and Prevention

In this section, we will discuss the steps that users and organizations can take to mitigate the risks posed by CVE-2023-22799 and prevent potential exploitation.

Immediate Steps to Take

Users are strongly advised to upgrade to a patched version of GlobalID beyond 1.0.1 to eliminate the vulnerability. Additionally, implementing security measures to filter and sanitize input can help mitigate the risk of a ReDoS-based DoS attack.

Long-Term Security Practices

To enhance overall security posture, organizations should incorporate regular security assessments, penetration testing, and code reviews to identify and address vulnerabilities like CVE-2023-22799 proactively. Building a robust incident response plan and conducting security awareness training are also crucial for long-term security resilience.

Patching and Updates

Staying vigilant for security updates and promptly applying patches released by the vendor is essential to safeguard against known vulnerabilities like CVE-2023-22799. Continuous monitoring of security advisories and maintaining an up-to-date software inventory are crucial for effective patch management and ensuring system security.
