A vulnerability was found in Moodle. Additional checks are required to ensure users with permission to view badge recipients can only access lists of those they are intended to have access to.

### Summary Missing `normalizePath` in the function `FileHelper::absolutePath` could lead to Remote Code Execution on the server via twig SSTI. `(Post-authentication, ALLOW_ADMIN_CHANGES=true)` ### Details Note: This is a sequel to [CVE-2023-40035](https://github.com/craftcms/cms/security/advisories/GHSA-44wr-rmwq-3phw) In [`src/helpers/FileHelper.php#L106-L137`](https://github.com/craftcms/cms/blob/5e56c6d168524ed02f0620c9bc1c9750f5b94e3b/src/helpers/FileHelper.php#L106-L137), the function `absolutePath` returned `$from . $ds . $to` without path normalization: ```php /** * Returns an absolute path based on a source location or the current working directory. * * @param string $to The target path. * @param string|null $from The source location. Defaults to the current working directory. * @param string $ds the directory separator to be used in the normalized result. Defaults to `DIRECTORY_SEPARATOR`. * @return string * @since 4.3.5 */ public static function absolutePath( ...

### Summary By abusing the mail notification template it is possible to read arbitrary operating system files. ### Details The [dataUrl](https://craftcms.com/docs/3.x/dev/functions.html#dataurl) function can be exploited if an attacker has write permissions on system notification templates. This function accepts an absolute file path, reads the file's content, and converts it into a Base64-encoded string. By embedding this function within a system notification template, the attacker can exfiltrate the Base64-encoded file content through a triggered system email notification. Once the email is received, the Base64 payload can be decoded, allowing the attacker to read arbitrary files on the server. Requirements: * write permissions to system notification templates * ability to trigger a corresponding system email ### PoC 1) Modify a template to contain the following twig template string: ```twig {{ dataUrl('/var/www/web/.env') }} ``` 2) Trigger the corresponding notification email (e...

### Summary A vulnerability in CraftCMS allows an attacker to bypass local file system validation by utilizing a double `file://` scheme (e.g., `file://file:////`). This enables the attacker to specify sensitive folders as the file system, leading to potential file overwriting through malicious uploads, unauthorized access to sensitive files, and, under certain conditions, remote code execution (RCE) via Server-Side Template Injection (SSTI) payloads. Note that this will only work if you have an authenticated administrator account with [allowAdminChanges enabled](https://craftcms.com/docs/5.x/reference/config/general.html#allowadminchanges). https://craftcms.com/knowledge-base/securing-craft#set-allowAdminChanges-to-false-in-production ### Details The issue lies in line 57 of `cms/src/helpers/FileHelper.php`, it only removes `file://` on the most left. It is trivial to bypass this sanitization by adding 2 `file://`, e.g. `file://file:////`. ```php public static function normaliz...

All versions of the package dom-iterator are vulnerable to Arbitrary Code Execution due to use of the Function constructor without complete input sanitization. Function generates a new function body and thus care must be given to ensure that the inputs to Function are not attacker-controlled. The risks involved are similar to that of allowing attacker-controlled input to reach eval.

# Microsoft Security Advisory CVE-2024-43498 | .NET Remote Code Execution Vulnerability ## <a name="executive-summary"></a>Executive summary Microsoft is releasing this security advisory to provide information about a vulnerability in .NET 9.0. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability. A remote unauthenticated attacker could exploit this vulnerability by sending specially crafted requests to a .NET vulnerable webapp or loading a specially crafted file into a vulnerable application. ## Announcement Announcement for this issue can be found at https://github.com/dotnet/announcements/issues/334 ## <a name="mitigation-factors"></a>Mitigation factors Applications that do not use the NrbfDecoder component are not affected by this vulnerability.

## Description When the `register_argc_argv php` directive is set to `on` , and users call any URL with a special crafted query string, they are able to change the environment used by the framework when handling the request. ## Resolution The framework now ignores argv values for environment detection on non-cli SAPIs.

### Summary A command injection vulnerability in the Web SSH feature allows an authenticated attacker to execute arbitrary commands as root on the host. ### Details Zoraxy has a Web SSH terminal feature that allows authenticated users to connect to SSH servers from their browsers. In [`HandleCreateProxySession`](https://github.com/tobychui/zoraxy/blob/9cb315ea6739d1cc201b690322d25166b12dc5db/src/webssh.go#L19) the request to create an SSH session is handled. After checking for the presence of required parameters, ensuring that the target is not the loopback interface and that there is actually an SSH service running on the target, `CreateNewConnection` is called: https://github.com/tobychui/zoraxy/blob/e79a70b7acfa45c2445aff9d60e4e7525c89fec8/src/mod/sshprox/sshprox.go#L165-L178 In line 178, the `gotty` binary is executed running `sshCommand` from the line above. It contains the user-controlled variable `connAddr`, which includes the hostname of the SSH server and - if provided - th...

This crate depended on a promise regarding alignments made by the author of the mimalloc allocator to avoid using aligned allocation functions where possible for performance reasons. Since then, the mimalloc allocator's logic changed, making it break this promise. This caused this crate to return memory with an incorrect alignment for some allocations, particularly those with large alignments. The flaw was fixed by always using the aligned allocation functions.
