# Microsoft Security Advisory CVE-2023-35390: .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 7.0 and .NET 6.0. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability. A vulnerability exists when some dotnet commands are used in directories with weaker permissions which can result in remote code execution. ## Announcement Announcement for this issue can be found at https://github.com/dotnet/announcements/issues/266 ### <a name="mitigation-factors"></a>Mitigation factors Microsoft has not identified any mitigating factors for this vulnerability. ## <a name="affected-software"></a>Affected software * Any .NET 7.0.1xx SDK 7.0.109 or earlier. * Any .NET 7.0.3xx SDK 7.0.306 or earlier. * Any .NET 6.0.1xx SDK 6.0.120 or earlier. * Any .NET 6.0.3xx SDK 6.0.315 or earlier. * A...

gRPC contains a vulnerability that allows hpack table accounting errors could lead to unwanted disconnects between clients and servers in exceptional cases/ Three vectors were found that allow the following DOS attacks: - Unbounded memory buffering in the HPACK parser - Unbounded CPU consumption in the HPACK parser The unbounded CPU consumption is down to a copy that occurred per-input-block in the parser, and because that could be unbounded due to the memory copy bug we end up with an O(n^2) parsing loop, with n selected by the client. The unbounded memory buffering bugs: - The header size limit check was behind the string reading code, so we needed to first buffer up to a 4 gigabyte string before rejecting it as longer than 8 or 16kb. - HPACK varints have an encoding quirk whereby an infinite number of 0’s can be added at the start of an integer. gRPC’s hpack parser needed to read all of them before concluding a parse. - gRPC’s metadata overflow check was performed per frame, so ...

Microsoft has patched a total of 74 flaws in its software as part of the company's Patch Tuesday updates for August 2023, down from the voluminous 132 vulnerabilities the company fixed last month. This comprises six Critical and 67 Important security vulnerabilities. Also released by the tech giant are two defense-in-depth updates for Microsoft Office (ADV230003) and the Memory Integrity System

Microsoft Corp. today issued software updates to plug more than 70 security holes in its Windows operating systems and related products, including a patch that addresses multiple zero-day vulnerabilities currently being exploited in the wild.

### Impact The `import-in-the-middle` loader works by generating a wrapper module on the fly. The wrapper uses the module specifier to load the original module and add some wrapping code. It allows for remote code execution in cases where an application passes user-supplied input directly to an import() function. ### Patches This vulnerability has been patched in `import-in-the-middle` version 1.4.2 ### Workarounds * Do not pass any user-supplied input to `import()`. Instead, verify it against a set of allowed values. * If using `import-in-the-middle` and support for EcmaScript Modules is not needed, ensure that none of the following options are set (either via command-line or the `NODE_OPTIONS` environment variable): ``` --loader=import-in-the-middle/hook.mjs --loader import-in-the-middle/hook.mjs ``` ### References If you have any questions or comments about this advisory, email us at [[email protected]](mailto:[email protected])

The only vulnerability Microsoft states is being exploited in the wild is CVE-2023-38180, a denial-of-service vulnerability in .NET and Microsoft Visual Studio.
