Ubuntu Security Notice 7058-1 - Brennan Conroy discovered that the .NET Kestrel web server did not properly handle closing HTTP/3 streams under certain circumstances. An attacker could possibly use this issue to achieve remote code execution. This vulnerability only impacted Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. It was discovered that .NET components designed to process malicious input were susceptible to hash flooding attacks. An attacker could possibly use this issue to cause a denial of service, resulting in a crash.

Microsoft has released security updates to fix a total of 118 vulnerabilities across its software portfolio, two of which have come under active exploitation in the wild. Of the 118 flaws, three are rated Critical, 113 are rated Important, and two are rated Moderate in severity. The Patch Tuesday update doesn't include the 25 additional flaws that the tech giant addressed in its Chromium-based

In livewire/livewire `< v3.5.2`, the file extension of an uploaded file is guessed based on the MIME type. As a result, the actual file extension from the file name is not validated. An attacker can therefore bypass the validation by uploading a file with a valid MIME type (e.g., `image/png`) and a “.php” file extension. If the following criteria are met, the attacker can carry out an RCE attack: - Filename is composed of the original file name using `$file->getClientOriginalName()` - Files stored directly on your server in a public storage disk - Webserver is configured to execute “.php” files ### PoC In the following scenario, an attacker could upload a file called `shell.php` with an `image/png` MIME type and execute it on the remote server. ```php class SomeComponent extends Component { use WithFileUploads; #[Validate('image|extensions:png')] public $file; public function save() { $this->validate(); $this->file->storeAs( path: 'i...

Threat actors are actively exploiting two of the vulnerabilities, while three others are publicly known and ripe for attack.

The two vulnerabilities that Microsoft reports have been actively exploited in the wild and are publicly known are both rated as only being of “moderate” severity.

# Microsoft Security Advisory CVE-2024-38229 | .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 8.0 and .NET 9.0. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability. A vulnerability exists in ASP.NET when closing an HTTP/3 stream while application code is writing to the response body, a race condition may lead to use-after-free. Note: HTTP/3 is experimental in .NET 6.0. If you are on .NET 6.0 and using HTTP/3, please upgrade to .NET 8.0.10. .NET 6.0 will not receive a security patch for this vulnerability. ## Announcement Announcement for this issue can be found at https://github.com/dotnet/announcements/issues/326 ## <a name="mitigation-factors"></a>Mitigation factors HTTP/3 support is not enabled by default in ASP.NET Core applications.
