A detailed overview of CVE-2022-30630, a vulnerability in the Go standard library affecting io/fs versions prior to 1.17.12 and 1.18.4.
Understanding CVE-2022-30630
This section will cover what CVE-2022-30630 entails, its impact, technical details, and mitigation strategies.
What is CVE-2022-30630?
CVE-2022-30630 refers to stack exhaustion in Glob on particular paths in io/fs before Go 1.17.12 and Go 1.18.4. This vulnerability allows an attacker to trigger a panic by causing stack exhaustion through a path containing numerous path separators.
The Impact of CVE-2022-30630
The vulnerability can lead to a denial of service (DoS) condition due to stack exhaustion, potentially resulting in service disruption or unavailability.
Technical Details of CVE-2022-30630
Explore the specifics of the vulnerability, including its description, affected systems and versions, and exploitation mechanism.
Vulnerability Description
The issue arises from uncontrolled recursion in Glob in io/fs, enabling a malicious actor to induce a panic by overloading the stack with a path pattern inundated with path separators.
Affected Systems and Versions
The vulnerability affects the Go standard library's io/fs package versions prior to 1.17.12 and 1.18.4.
Exploitation Mechanism
By leveraging uncontrolled recursion in Glob, threat actors can craft a path with a high volume of path separators to trigger stack exhaustion and provoke a panic.
Mitigation and Prevention
Discover the steps to mitigate the vulnerability and prevent potential exploitation.
Immediate Steps to Take
Users are advised to update to Go versions 1.17.12 or 1.18.4 to mitigate the vulnerability and prevent stack exhaustion attacks.
Long-Term Security Practices
Employ secure coding practices, limit path complexity, and conduct regular security assessments to enhance overall system resilience.
Patching and Updates
Stay vigilant for security advisories from the Go community and promptly apply patches and updates to address known vulnerabilities.
