CVE-2024-22050: 
Ruby vulnerability analysis and mitigation

Path traversal vulnerability (CVE-2024-22050) affects the static file service in Iodine versions less than 0.7.33. The vulnerability was discovered and disclosed in October 2019, affecting the Ruby-based Iodine web server. This security flaw allows unauthenticated remote attackers to read files outside the public folder through malicious URL manipulation (GitHub Advisory).

The vulnerability exists in the static file service component of Iodine, where insufficient path validation allows for directory traversal attacks. The issue has been assigned a CVSS v3.1 base score of 7.5 (HIGH) with vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N, indicating network accessibility, low attack complexity, and no required privileges or user interaction (NVD).

When exploited, this vulnerability allows attackers to read files that exist outside the intended public folder through malicious URL crafting. This could potentially expose sensitive server-side files and lead to information disclosure (GitHub Advisory).

The vulnerability has been patched in Iodine version 0.7.34. Users are strongly recommended to upgrade to this version. As a temporary workaround, users can disable the static file service and its X-Sendfile support, instead using nginx or a dynamic source code solution for serving static files. However, upgrading to the latest version is the recommended solution as it also includes non-security related fixes (GitHub Advisory).
