CVE-2022-42943: 
Autodesk Design Review vulnerability analysis and mitigation

CVE-2022-42943 is a Remote Code Execution vulnerability discovered in Autodesk Design Review that affects the processing of Design Web Format (DWF) files. The vulnerability was discovered by Kushal Arvind Shah of Fortinet's FortiGuard Labs and was disclosed in October 2022. The vulnerability specifically affects the DesignReview.exe application when processing malformed DWF files (Fortinet Blog).

The vulnerability is caused by a malformed DWF file, which triggers an Out of Bounds memory write due to an improper bounds check in the application. This memory corruption vulnerability occurs during the decoding process of Design Web Format (DWF) files in the DesignReview.exe application (Fortinet Blog, Autodesk Advisory).

If successfully exploited, attackers can execute arbitrary code within the context of the application via a crafted DWF file. This could potentially allow unauthorized control over the affected system when a malicious file is processed (Fortinet Blog).

The vulnerability requires user interaction to be exploited, as the target must open a maliciously crafted DWF file through the DesignReview.exe application. Fortinet has released an IPS signature named 'Autodesk.Design.Review.CVE-2022-42943.Remote.Code.Execution' to protect against exploitation attempts (Fortinet Blog).

Autodesk has released security patches to address this vulnerability. Users of Autodesk Design Review 2018 are advised to install Hotfix 5 or later versions. The fix is available through the Autodesk Knowledge Network. Additionally, FortiGuard Labs has released IPS signatures to detect and prevent exploitation attempts (Autodesk Advisory).
