Exploitability
| CWE ID | Description |
|---|---|
| CWE-59 | The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource. |
| CWE-61 | The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in Static Web Server (SWS) versions 2.40.0 and below, where symbolic links (symlinks) can be used to access files or directories outside the intended web root folder. The server does not prevent symlinks from escaping the root directory, allowing a malicious actor who has access to the web server's root directory to create symlinks that point to files outside the designated web root. This can be exploited either by URL or via directory listing. The issue is fixed in version 2.40.1.
How can this vulnerability impact me? :
If exploited, this vulnerability can allow an attacker to access sensitive files or directories outside the web server's intended root folder. This could lead to unauthorized disclosure of information, potentially exposing confidential data or system files that should not be publicly accessible.
What immediate steps should I take to mitigate this vulnerability?
Upgrade Static Web Server (SWS) to version 2.40.1 or later, as this version fixes the symlink issue that allows access outside the web root folder. Additionally, restrict access to the web server's root directory to prevent unauthorized creation of symbolic links.
