CVE-2024-30090: 
vulnerability analysis and mitigation

Microsoft Streaming Service Elevation of Privilege Vulnerability (CVE-2024-30090) was discovered and disclosed on June 11, 2024. This vulnerability affects various versions of Microsoft Windows operating systems and their Kernel Streaming service framework, which handles data streams from devices like webcams and microphones. The vulnerability has been assigned a CVSS score of 7.0 (HIGH) (SecurityOnline).

The vulnerability stems from a race condition in the Kernel Streaming framework that operates in kernel mode. The issue specifically occurs when nt!SeDebugPrivilege is changed, allowing non-administrative users to gain PROCESS_ALL_ACCESS to high-privilege processes. The vulnerability has been assigned CVSS vector string CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H and is associated with CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-822 (Untrusted Pointer Dereference) (NVD).

Successful exploitation of this vulnerability could allow an attacker to gain SYSTEM privileges on affected Windows systems. The attack bypasses the need for SeDebugPrivilege, which typically requires administrative control, by exploiting how Windows checks process privileges (SecurityOnline).

Microsoft released patches for this vulnerability during their June 2024 Patch Tuesday update. Users are strongly advised to apply these security updates immediately to protect their systems from potential exploitation (SecurityOnline).
