The AVGUI.exe of AVG/Avast Antivirus before versions before 24.1 can allow a local attacker to escalate privileges via an COM hijack in a time-of-check to time-of-use (TOCTOU) when self protection is disabled.

The vulnerability potentially allowed an attacker to misuse ESET’s file operations during the removal of a detected file on the Windows operating system to delete files without having proper permissions to do so.

The Security, Antivirus, Firewall – S.A.F plugin for WordPress is vulnerable to IP Address Spoofing in versions up to, and including, 2.3.5. This is due to insufficient restrictions on where the IP Address information is being retrieved for request logging and login restrictions. Attackers can supply the X-Forwarded-For header with with a different IP Address that will be logged and can be used to bypass settings that may have blocked out an IP address from logging in.

Denial of service vulnerability present shortly after product installation or upgrade, potentially allowed an attacker to render ESET’s security product inoperable, provided non-default preconditions were met.

Local privilege escalation vulnerability allowed an attacker to misuse ESET's file operations during a restore operation from quarantine.

A sym-linked file accessed via the repair function in Avast Antivirus <24.2 on Windows may allow user to elevate privilege to delete arbitrary files or run processes as NT AUTHORITY\SYSTEM. The vulnerability exists within the "Repair" (settings -> troubleshooting -> repair) feature, which attempts to delete a file in the current user's AppData directory as NT AUTHORITY\SYSTEM. A low-privileged user can make a pseudo-symlink and a junction folder and point to a file on the system. This can provide a low-privileged user an Elevation of Privilege to win a race-condition which will re-create the system files and make Windows callback to a specially-crafted file which could be used to launch a privileged shell instance. This issue affects Avast Antivirus prior to 24.2.
