漏洞标题
changedetection.io中存在目录遍历漏洞
漏洞描述信息
changedetection.io 是一个免费的开源网页变更检测工具。该工具对于文件URI模式的验证不足,导致攻击者能够读取系统中的任意文件。此问题仅影响启用了webdriver且`ALLOW_FILE_URI`设置为false或未定义的实例。用于检查URL协议的`is_safe_url`函数允许`file:`作为URL模式。它随后检查是否允许本地文件,但检查的一个前提条件是URL以`file://`开头。问题在于文件URI模式无需包含双斜杠。此漏洞已在0.47.06版本中得到解决,建议所有用户进行升级。目前尚无针对此漏洞的解决方法。

漏洞标题
Path traversal using file URI scheme without supplying hostname in changedetection.io
漏洞描述信息
changedetection.io is a free open source web page change detection tool. The validation for the file URI scheme falls short, and results in an attacker being able to read any file on the system. This issue only affects instances with a webdriver enabled, and `ALLOW_FILE_URI` false or not defined. The check used for URL protocol, `is_safe_url`, allows `file:` as a URL scheme. It later checks if local files are permitted, but one of the preconditions for the check is that the URL starts with `file://`. The issue comes with the fact that the file URI scheme is not required to have double slashes. This issue has been addressed in version 0.47.06 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
