Microsoft AutoUpdate (MAU) Elevation of Privilege Vulnerability

A race condition vulnerability exists in the QuickClean feature of McAfee Total Protection for Windows prior to 16.0.43 that allows a local user to gain privilege elevation and perform an arbitrary file delete. This could lead to sensitive files being deleted and potentially cause denial of service. This attack exploits the way symlinks are created and how the product works with them.

BASupSrvcUpdater.exe in N-able Take Control Agent through 7.0.41.1141 before 7.0.43 has a TOCTOU Race Condition via a pseudo-symlink at %PROGRAMDATA%\GetSupportService_N-Central\PushUpdates, leading to arbitrary file deletion.

Windows Graphics Component Elevation of Privilege Vulnerability

A Time-of-Check Time-Of-Use vulnerability in the Trend Micro Apex One Vulnerability Protection integrated component could allow a local attacker to escalate privileges and turn a specific working directory into a mount point on affected installations. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

A vulnerability exists in Trend Micro Maximum Security 2022 (17.7) wherein a low-privileged user can write a known malicious executable to a specific location and in the process of removal and restoral an attacker could replace an original folder with a mount point to an arbitrary location, allowing a escalation of privileges on an affected system.

Acrobat Reader versions 20.005.30636, 24.002.20965, 24.002.20964, 24.001.30123 and earlier are affected by a Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability that could lead to privilege escalation. Exploitation of this issue require local low-privilege access to the affected system and attack complexity is high.

Windows Perception Service Elevation of Privilege Vulnerability

Windows Kernel Elevation of Privilege Vulnerability

Windows Kernel Elevation of Privilege Vulnerability

Windows Kernel-Mode Driver Elevation of Privilege Vulnerability

A logged in user may elevate its permissions by abusing a Time-of-Check to Time-of-Use (TOCTOU) race condition. When a particular process flow is initiated, an attacker can exploit this condition to gain unauthorized elevated privileges on the affected system.

Windows Print Spooler Elevation of Privilege Vulnerability

A Time-of-Check Time-Of-Use vulnerability in the Trend Micro Apex One and Apex One as a Service agent could allow a local attacker to escalate privileges on affected installations. Please note: a local attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. This is similar to, but not identical to CVE-2023-32554.

The Netskope client service (prior to R96) on Windows runs as NT AUTHORITY\SYSTEM which writes log files to a writable directory (C:\Users\Public\netSkope) for a standard user. The files are created and written with a SYSTEM account except one file (logplaceholder) which inherits permission giving all users full access control list. Netskope client restricts access to this file by allowing only read permissions as a standard user. Whenever the Netskope client service restarts, it deletes the logplaceholder and recreates, creating a race condition, which can be exploited by a malicious local user to create the file and set ACL permissions on the file. Once the file is created by a malicious user with proper ACL permissions, all files within C:\Users\Public\netSkope\ becomes modifiable by the unprivileged user. By using Windows pseudo-symlink, these files can be pointed to other places in the system and thus malicious users will be able to elevate privileges.

An issue was discovered in Plex Media Server through 1.24.4.5081-e362dc1ee. An attacker (with a foothold in a endpoint via a low-privileged user account) can access the exposed RPC service of the update service component. This RPC functionality allows the attacker to interact with the RPC functionality and execute code from a path of his choice (local, or remote via SMB) because of a TOCTOU race condition. This code execution is in the context of the Plex update service (which runs as SYSTEM).

Windows Projected File System Elevation of Privilege Vulnerability

Microsoft Defender Elevation of Privilege Vulnerability

A Time-of-Check Time-Of-Use vulnerability in the Trend Micro Apex One and Apex One as a Service agent could allow a local attacker to escalate privileges on affected installations. Please note: a local attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. This is similar to, but not identical to CVE-2023-32555.

An elevation of privilege vulnerability exists in the way that the ssdpsrv.dll handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions. To exploit the vulnerability, a locally authenticated attacker could run a specially crafted application. The security update addresses the vulnerability by ensuring the ssdpsrv.dll properly handles objects in memory.
