What is CVE-2022-1471?
CVE-2022-1471 is a critical security vulnerability affecting the SnakeYaml library, specifically versions up to (excluding) 2.0. This vulnerability occurs due to the Constructor() class not restricting types that can be instantiated during deserialization, potentially leading to remote code execution.
Systems using SnakeYaml to deserialize YAML content from untrusted sources are at risk. To mitigate this issue, it is recommended to use SnakeYaml's SafeConstructor when parsing untrusted content and upgrade to version 2.0 or later.
Who Is Impacted By CVE-2022-1471?
If you're using the SnakeYaml library to deserialize YAML content, you might be affected by this vulnerability. This issue impacts SnakeYaml versions up to (excluding) 2.0.
To determine if you're affected, check if you're using SnakeYaml's Constructor() class to deserialize content from untrusted sources. If so, consider switching to the SafeConstructor to restrict deserialization and look out for the release of SnakeYaml version 2.0, which includes a fix for this vulnerability.
What To Do If CVE-2022-1471 Affected You
If you're affected by this vulnerability, take these steps: 1) Use SnakeYaml's SafeConstructor when parsing untrusted YAML content to restrict deserialization, 2) Upgrade to SnakeYaml version 2.0 or later for improved security, and 3) Review your application's usage of SnakeYaml to ensure secure parsing of untrusted content.
Is CVE-2022-1471 in CISA’s Known Exploited Vulnerabilities Catalog?
Yes, it is in CISA's Known Exploited Vulnerabilities Catalog. The vulnerability, named SnakeYaml Deserialization Remote Code Execution, was added on December 1, 2022. The required action is to upgrade to SnakeYaml version 2.0 or later and use the SafeConstructor when parsing untrusted content to restrict deserialization.
CVE-2022-1471 Weakness Enumeration
This vulnerability involves two weaknesses: deserialization of untrusted data CWE-502 and improper input validation (CWE-20), which can lead to remote code execution.
