Technical details

An information disclosure vulnerability (CWE-200) exists in Windows Media across multiple versions of Windows and Windows Server. The vulnerability allows an attacker with local access and low privileges (PR:L) to disclose sensitive information to an unauthorized actor. The attack vector is local (AV:L), meaning the attacker must have the ability to execute code on the target system. The impact is limited to confidentiality (C:H) with no impact on system integrity or availability. Microsoft has released security updates to address this issue across affected versions including Windows 10, Windows 11, and Windows Server 2012 R2.
