While the exact aspects of the in-the-wild exploitation remain mysterious, cybersecurity agency Numen Cyber has deconstructed the patch launched by Microsoft and created a proof-of-thought (PoC) exploit for Windows Server 2016.
In its advisory, Numen Cyber highlighted that Win32k vulnerabilities have a record. Microsoft has attempted to refactor this component of the kernel code applying Rust in the most up-to-date Windows 11 preview model, which might do away with this kind of vulnerabilities in the long term.
The vulnerability will allow lower-privileged consumers to receive Program privileges, the maximum consumer mode privileges in Windows. Cybersecurity firm Avast was initial credited with discovering the flaw, revealing that it was actively exploited as a zero-day in attacks.
Quickly ahead to this 7 days, Numen Cyber warned that exploiting this vulnerability does not demand novel procedures and intensely depends on leaked desktop heap handle addresses. Thus, more mature techniques remain at risk if this issue is not tackled completely.
“While this vulnerability looks to be non-exploitable on the Earn11 program variation, it poses a substantial risk to previously techniques,” reads the complex publish-up.
Process administrators are suggested to be vigilant for abnormal offset reads and writes in memory or linked to window objects, as they may show energetic exploitation of CVE-2023-29336 for regional privilege escalation.
Additional vulnerabilities possibly letting attackers to achieve elevated privileges were being recently uncovered in the preferred graphics debugger RenderDoc.
