In version 1.4.3, arbitrary file reads allow an attacker to read arbitrary important configuration files on the server. In the `api/v1/file.go` file, there is a function called `LoadFromFile`, which directly reads the file by obtaining the requested path `parameter[path]`. The request parameters are not filtered, resulting in a background arbitrary file reading vulnerability. Version 1.5.0 has a patch for this issue.","dueDate":"","id":"CVE-2023-39964","kev_catalogs":["vulncheck"],"knownRansomwareCampaignUse":"Unknown","product":"1panel","requiredAction":"Apply remediations or mitigations per vendor instructions or discontinue use of the product if remediation or mitigations are unavailable.","severity":"HIGH","source":"vulncheck_kev","title":"fit2cloud 1panel Improper Limitation of a Pathname to a Restricted Directory","vendor":"fit2cloud"}
