CVE-2022-26945 : What You Need to Know

This article provides detailed information about CVE-2022-26945, a vulnerability in the go-getter library that allowed protocol switching, endless redirect, and configuration bypass.

Understanding CVE-2022-26945

CVE-2022-26945 is a vulnerability in the go-getter library that permitted attackers to execute protocol switching, create endless redirects, and evade configuration restrictions through the abuse of custom HTTP response header processing.

What is CVE-2022-26945?

The CVE-2022-26945 vulnerability affected go-getter versions up to 1.5.11 and 2.0.2, allowing malicious actors to carry out various attacks leveraging the mishandling of HTTP response headers. The issue was resolved in versions 1.6.1 and 2.1.0 of the library.

The Impact of CVE-2022-26945

The impact of CVE-2022-26945 could result in unauthorized access, data leakage, server compromise, and potential denial-of-service (DoS) attacks. Attackers could exploit this vulnerability to manipulate HTTP requests and responses, leading to serious security implications.

Technical Details of CVE-2022-26945

The following technical details describe the vulnerability and its potential impact on affected systems and environments:

Vulnerability Description

The flaw in the go-getter library allowed for protocol switching, endless redirects, and configuration bypass by exploiting the handling of custom HTTP response headers. This could enable attackers to perform various malicious activities, posing a significant risk to systems.

Affected Systems and Versions

The vulnerability impacted go-getter versions up to 1.5.11 and 2.0.2, leaving systems utilizing these versions exposed to potential attacks exploiting the mismanagement of HTTP response header processing.

Exploitation Mechanism

By abusing the custom HTTP response header processing, threat actors could manipulate the communication flow between the client and server, facilitating protocol switching, redirect loops, and bypassing configuration restrictions.

Mitigation and Prevention

To address CVE-2022-26945 and enhance the security posture of your systems, consider implementing the following mitigation strategies:

Immediate Steps to Take

Upgrade to the patched versions 1.6.1 or 2.1.0 of the go-getter library to prevent exploitation of the vulnerability.
Regularly monitor and review HTTP request and response handling mechanisms to detect any suspicious activities.

Long-Term Security Practices

Conduct regular security audits and assessments to identify and remediate vulnerabilities in third-party libraries.
Implement robust security controls, such as input validation and output encoding, to mitigate risks associated with HTTP header manipulation.

Patching and Updates

Stay informed about security updates and patches released by the library maintainers. Promptly apply patches to ensure that your systems are protected against known vulnerabilities.
