Valve Steam Client for Windows through 2019-08-20 has weak folder permissions, leading to privilege escalation (to NT AUTHORITY\SYSTEM) via crafted use of CreateMountPoint.exe and SetOpLock.exe to leverage a TOCTOU race condition.

Valve Steam Client for Windows through 2019-08-16 allows privilege escalation (to NT AUTHORITY\SYSTEM) because local users can replace the current versions of SteamService.exe and SteamService.dll with older versions that lack the CVE-2019-14743 patch.

Realtek Waves MaxxAudio driver 1.6.2.0, as used on Dell laptops, installs with incorrect file permissions. As a result, a local attacker can escalate to SYSTEM.

Netwrix Auditor before 9.8 has insecure permissions on %PROGRAMDATA%\Netwrix Auditor\Logs\ActiveDirectory\ and sub-folders. In addition, the service Netwrix.ADA.StorageAuditService (which writes to that directory) does not perform proper impersonation, and thus the target file will have the same permissions as the invoking process (in this case, granting Authenticated Users full access over the target file). This vulnerability can be triggered by a low-privileged user to perform DLL Hijacking/Binary Planting attacks and ultimately execute code as NT AUTHORITY\SYSTEM with the help of Symbolic Links.

3CX Phone 15 on Windows has insecure permissions on the "%PROGRAMDATA%\3CXPhone for Windows\PhoneApp" installation directory, allowing Full Control access for Everyone, and leading to privilege escalation because of a StartUp link.

ghostscript: -dSAFER escape in .charkeys (701841)

A flaw was found in all versions of ghostscript 9.x before 9.50, where the `.charkeys` procedure, where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. An attacker could abuse this flaw by creating a specially crafted PostScript file that could escalate privileges within the Ghostscript and access files outside of restricted areas or execute commands.

ghostscript: Safer mode bypass by .forceput exposure in setuserparams (701444)

A flaw was found in all ghostscript versions 9.x before 9.50, in the .setuserparams2 procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.

In Valve Steam Client for Windows through 2019-08-07, HKLM\SOFTWARE\Wow6432Node\Valve\Steam has explicit "Full control" for the Users group, which allows local users to gain NT AUTHORITY\SYSTEM access.

Improper permissions in Intel(R) DAAL before version 2020 Gold may allow an authenticated user to potentially enable information disclosure via local access.

AdRem NetCrunch 10.6.0.4587 has an Improper Session Handling vulnerability in the NetCrunch web client, which can lead to an authentication bypass or escalation of privileges.

cPanel before 80.0.5 uses world-readable permissions for the Queueprocd log (SEC-494).

chromium-browser: Bypass on download restrictions

Insufficient data validation in downloads in Google Chrome prior to 77.0.3865.75 allowed a remote attacker to bypass download restrictions via a crafted HTML page.

chromium-browser: User gesture needed for printing

Insufficient policy enforcement in PDFium in Google Chrome prior to 77.0.3865.75 allowed a remote attacker to show print dialogs via a crafted PDF file.

chromium-browser: Chrome web store origin needs to be isolated

Insufficient policy enforcement in site isolation in Google Chrome prior to 77.0.3865.75 allowed a remote attacker to bypass site isolation via a crafted HTML page.

chromium-browser: Google URI shown for certificate warning

Insufficient policy enforcement in Chromium in Google Chrome prior to 77.0.3865.75 allowed a remote attacker to perform domain spoofing via a crafted HTML page.

chromium-browser: Multiple file download protection bypass

Insufficient filtering in Blink in Google Chrome prior to 77.0.3865.75 allowed a remote attacker to bypass multiple file download protection via a crafted HTML page.

In Total Defense Anti-virus 9.0.0.773, insecure access control for the directory %PROGRAMDATA%\TotalDefense\Consumer\ISS\9\bd\TDUpdate2\ used by AMRT.exe allows local attackers to hijack bdcore.dll, which leads to privilege escalation when the AMRT service loads the DLL.

In Total Defense Anti-virus 9.0.0.773, insecure access control for the directory %PROGRAMDATA%\TotalDefense\Consumer\ISS\9\ used by ccschedulersvc.exe allows local attackers to hijack dotnetproxy.exe, which leads to privilege escalation when the ccSchedulerSVC service runs the executable.

This vulnerability allows network adjacent attackers to execute arbitrary code on affected installations of Xiaomi Browser Prior to 10.4.0. User interaction is required to exploit this vulnerability in that the target must connect to a malicious access point. The specific flaw exists within the handling of HTTP responses to the Captive Portal. A crafted HTML response can cause the Captive Portal to to open a browser to a specified location without user interaction. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process. Was ZDI-CAN-7467.
