ESET products for Windows allows untrusted process to impersonate the client of a pipe, which can be leveraged by attacker to escalate privileges in the context of NT AUTHORITY\SYSTEM.
ESET was made aware of a vulnerability in its consumer and business products for macOS that enables a user logged on to the system to stop the ESET daemon, effectively disabling the protection of the ESET security product until a system reboot.
A local (authenticated) low-privileged user can exploit a behavior in an ESET installer to achieve arbitrary file overwrite (deletion) of any file via a symlink, due to insecure permissions. The possibility of exploiting this vulnerability is limited and can only take place during the installation phase of ESET products. Furthermore, exploitation can only succeed when Self-Defense is disabled. Affected products are: ESET NOD32 Antivirus, ESET Internet Security, ESET Smart Security, ESET Smart Security Premium versions 13.2 and lower; ESET Endpoint Antivirus, ESET Endpoint Security, ESET NOD32 Antivirus Business Edition, ESET Smart Security Business Edition versions 7.3 and lower; ESET File Security for Microsoft Windows Server, ESET Mail Security for Microsoft Exchange Server, ESET Mail Security for IBM Domino, ESET Security for Kerio, ESET Security for Microsoft SharePoint Server versions 7.2 and lower.
ESET Antivirus and Antispyware Module module 1553 through 1560 allows a user with limited access rights to create hard links in some ESET directories and then force the product to write through these links into files that would normally not be write-able by the user, thus achieving privilege escalation.
ESET Archive Support Module before 1294 allows virus-detection bypass via crafted RAR Compression Information in an archive. This affects versions before 1294 of Smart Security Premium, Internet Security, NOD32 Antivirus, Cyber Security Pro (macOS), Cyber Security (macOS), Mobile Security for Android, Smart TV Security, and NOD32 Antivirus 4 for Linux Desktop.
The ESET AV parsing engine allows virus-detection bypass via a crafted BZ2 Checksum field in an archive. This affects versions before 1294 of Smart Security Premium, Internet Security, NOD32 Antivirus, Cyber Security Pro (macOS), Cyber Security (macOS), Mobile Security for Android, Smart TV Security, and NOD32 Antivirus 4 for Linux Desktop.
ESET Cyber Security before 6.8.1.0 is vulnerable to a denial-of-service allowing any user to stop (kill) ESET processes. An attacker can abuse this bug to stop the protection from ESET and launch his attack.
A permissions issue in ESET Cyber Security before 6.8.300.0 for macOS allows a local attacker to escalate privileges by appending data to root-owned files.
ESET Archive Support Module before 1296 allows virus-detection bypass via a crafted Compression Information Field in a ZIP archive. This affects versions before 1294 of Smart Security Premium, Internet Security, NOD32 Antivirus, Cyber Security Pro (macOS), Cyber Security (macOS), Mobile Security for Android, Smart TV Security, and NOD32 Antivirus 4 for Linux Desktop.
ESET Cyber Security 6.7.900.0 for macOS allows a local attacker to execute unauthorized commands as root by abusing an undocumented feature in scheduled tasks.
