How CVE-2022-24785 MomentJS Path Traversal Works: Detailed Exploit Guide
CVE-2022-24785 is a path traversal vulnerability found in Moment.js, a JavaScript library used for date parsing, validation, manipulation, and formatting. This vulnerability affects npm users of Moment.js versions 1.0.1 to 2.29.1, where a user-provided locale string can be misused to switch the moment locale if not properly sanitized. The issue lies within the `loadLocale` function of Moment.js, which dynamically requires a module based on user input without proper validation, potentially allowing attackers to load malicious modules or execute arbitrary code. The vulnerability is demonstrated through an example application that uses the vulnerable function to format time based on a user-provided locale, highlighting how an attacker could exploit this by passing a specially crafted string. The vulnerability has been patched in version 2.29.2 of Moment.js by adding a validation function `isLocaleNameSane` to ensure locale names do not resemble filesystem paths, effectively mitigating the risk of path traversal attacks. The discovery of this vulnerability and its proof of concept were a collaborative effort, emphasizing the importance of community collaboration in identifying and addressing security vulnerabilities.
