CVE-2022-39310 : What You Need to Know

A malicious agent may be able to impersonate another agent in GoCD, leading to potential information disclosure. This CVE impacts GoCD versions prior to 21.1.0 due to broken access control and incorrect validation of agent tokens.

Understanding CVE-2022-39310

What is CVE-2022-39310?

CVE-2022-39310 highlights a vulnerability in GoCD versions before 21.1.0 that allows an authenticated agent to impersonate another agent, potentially resulting in accidental information disclosure.

The Impact of CVE-2022-39310

The vulnerability can lead to a malicious agent receiving work packages intended for other agents, including sensitive information like credentials. Exploitation requires knowledge of agent identifiers and the ability to authenticate as an existing agent within the GoCD server.

Technical Details of CVE-2022-39310

Vulnerability Description

The issue arises from broken access control and incorrect validation of agent tokens in GoCD servers, enabling one agent to impersonate another and access sensitive work packages.

Affected Systems and Versions

GoCD versions prior to 21.1.0 are impacted by this vulnerability, categorizing them as 'affected' due to the identified security issue.

Exploitation Mechanism

Successful exploitation involves an attacker leveraging the broken access control to authenticate as another agent and intercept their work packages, potentially leading to information leaks.

Mitigation and Prevention

Immediate Steps to Take

It is crucial to upgrade GoCD servers to version 21.1.0 or later to mitigate the vulnerability and prevent unauthorized access and information disclosure.

Long-Term Security Practices

Incorporate proper access control and validation mechanisms in continuous delivery server setups to prevent unauthorized agent impersonation and safeguard sensitive information.

Patching and Updates

Deploying the fixed version, 21.1.0, addresses the vulnerability and ensures that agents are protected from potential impersonation attacks.
