Local privilege escalation potentially allowed an attacker to write an arbitrary file with fully controlled content as a privileged user.

Local privilege escalation potentially allowed an attacker to execute arbitrary code as a privileged user.

Use-after-free vulnerability in ESET Linux products potentially allowed an attacker to trigger kernel panic on the system

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.

Cross-site scripting (XSS) vulnerability in the Additional Report Settings interface in ESET Remote Administrator before 3.0.105 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors. NOTE: some of these details are obtained from third party information.

The Personal Firewall driver (aka epfw.sys) 3.0.672.0 and earlier in ESET Smart Security 3.0.672 and earlier allows local users to gain privileges via a crafted IRP in a certain METHODNEITHER IOCTL request to \Device\Epfw that overwrites portions of memory.

ESET NOD32 Antivirus 3662 and possibly 3440, when Internet Explorer 6 or 7 is used, allows remote attackers to bypass detection of malware in an HTML document by placing an MZ header (aka "EXE info") at the beginning, and modifying the filename to have (1) no extension, (2) a .txt extension, or (3) a .jpg extension, as demonstrated by a document containing a CVE-2006-5745 exploit.

ESET Smart Security, when Internet Explorer 6 or 7 is used, allows remote attackers to bypass detection of malware in an HTML document by placing an MZ header (aka "EXE info") at the beginning, and modifying the filename to have (1) no extension, (2) a .txt extension, or (3) a .jpg extension, as demonstrated by a document containing a CVE-2006-5745 exploit.

The esetsdaemon service in ESET Endpoint Antivirus for macOS before 6.4.168.0 and Endpoint Security for macOS before 6.4.168.0 does not properly verify X.509 certificates from the edf.eset.com SSL server, which allows man-in-the-middle attackers to spoof this server and provide crafted responses to license activation requests via a self-signed certificate. NOTE: this issue can be combined with CVE-2016-0718 to execute arbitrary code remotely as root.

User enumeration in ESET Protect (on-prem) via Response Timing.

Local privilege escalation vulnerability via insecure temporary batch file execution in ESET Management Agent

Planting a custom configuration file

in

ESET Inspect Connector allow load a malicious DLL.

Local privilege escalation vulnerability potentially allowed an attacker to misuse ESET’s file operations to delete files without having proper permission.

Tampering of the registry entries might have led to preventing the ESET security products from starting correctly on the next system startup or to unauthorized changes in the product's configuration.

Time-of-check to time-of-use race condition vulnerability potentially allowed an attacker to use the installed ESET security software to clear the content of an arbitrary file on the file system.

Installation file of ESET security products on Windows

allow an attacker to misuse to delete an arbitrary file without having the permissions to do so.

DLL Search Order Hijacking vulnerability potentially allowed an attacker with administrator privileges to load a malicious dynamic-link library and execute its code.

During internal security analysis, a local privilege escalation vulnerability has been identified. On a machine with the affected ESET product installed, it was possible for a user with lower privileges due to improper privilege management to trigger actions with root privileges.

ESET remedied this possible attack vector and has prepared new builds of its products that are no longer susceptible to this vulnerability.

Unquoted service path in ESET products allows to

drop a prepared program to a specific location and run on boot with the

NT AUTHORITY\NetworkService permissions.

The vulnerability potentially allows an attacker to misuse ESET’s file operations during the module update to delete or move files without having proper permissions.

Products for macOS enables a user logged on to the system to perform a denial-of-service attack, which could be misused to disable the protection of the ESET security product and cause general system slow-down.

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.

Heap-based buffer overflow in the Archive support module in ESET NOD32 before update 11861 allows remote attackers to execute arbitrary code via a large number of languages in an EPOC installation file of type SISFILEMULTILANG.

The vulnerability in the driver dlpfde.sys enables a user logged into the system to perform system calls leading to kernel stack overflow, resulting in a system crash, for instance, a BSOD.

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.
