# microsoft .net framework: .NET Framework Information Disclosure Vulnerability

Microsoft .NET Framework leaks the ObjRef URI to an attacker, which can be chained into remote code execution. CISA lists it as actively exploited in the wild.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Microsoft .NET Framework affected ? fixed ?
- vendor:microsoft .net framework affected = 3.5 fixed ?
- vendor:microsoft .net framework affected = 4.7.2 fixed ?
- vendor:microsoft .net framework affected = 4.8 fixed ?
- vendor:microsoft .net framework affected = 3.5.1 fixed ?
- vendor:microsoft .net framework affected = 2.0 fixed ?
- vendor:microsoft .net framework affected = 3.0 fixed ?
- vendor:microsoft .net framework affected = 4.6 fixed ?
- vendor:microsoft .net framework affected = 4.6.2 fixed ?
- vendor:microsoft .net framework affected = 4.8.1 fixed ?
- vendor:microsoft .net framework affected = 4.7 fixed ?
- vendor:microsoft .net framework affected = 4.7.1 fixed ?

## Fix

Apply Microsoft's vendor mitigations per CISA guidance, or discontinue use of the affected .NET Framework component if mitigations are unavailable.

## From the sources

Microsoft .NET Framework contains an information disclosure vulnerability that exposes the ObjRef URI to an attacker, ultimately enabling remote code execution.

CISA required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
