Vulnerabilities

Kaspersky has fixed a security issue in the Kaspersky Security 8.0 for Linux Mail Server. The issue was that an attacker could potentially force an administrator to click on a malicious link to perform unauthorized actions.

Kaspersky VPN Secure Connection for Windows version up to 21.5 was vulnerable to arbitrary file deletion via abuse of its 'Delete All Service Data And Reports' feature by the local authenticated attacker.

Kaspersky Anti-Virus products for home and Kaspersky Endpoint Security with antivirus databases released before 12 March 2022 had a bug in a data parsing module that potentially allowed an attacker to execute arbitrary code. The fix was delivered automatically. Credits: Georgy Zaytsev (Positive Technologies).

A component in Kaspersky Password Manager could allow an attacker to elevate a process Integrity level from Medium to High.

Possible system denial of service in case of arbitrary changing Firefox browser parameters. An attacker could change specific Firefox browser parameters file in a certain way and then reboot the system to make the system unbootable.

Password generator feature in Kaspersky Password Manager was not completely cryptographically strong and potentially allowed an attacker to predict generated passwords in some cases. An attacker would need to know some additional information (for example, time of password generation).

KIS for macOS in some use cases was vulnerable to AV bypass that potentially allowed an attacker to disable anti-virus protection.

A component of Kaspersky custom boot loader allowed loading of untrusted UEFI modules due to insufficient check of their authenticity. This component is incorporated in Kaspersky Rescue Disk (KRD) and was trusted by the Authentication Agent of Full Disk Encryption in Kaspersky Endpoint Security (KES). This issue allowed to bypass the UEFI Secure Boot security feature. An attacker would need physical access to the computer to exploit it. Otherwise, local administrator privileges would be required to modify the boot loader component.

TinyCheck before commits 9fd360d and ea53de8 was vulnerable to command injection due to insufficient checks of input parameters in several places.

In TinyCheck before commits 9fd360d and ea53de8, the installation script of the tool contained hard-coded credentials to the backend part of the tool. This information could be used by an attacker for unauthorized access to remote data.

The installer of Kaspersky Anti-Ransomware Tool (KART) prior to KART 4.0 Patch C was vulnerable to a DLL hijacking attack that allowed an attacker to elevate privileges during installation process.

Installers of Kaspersky Security Center and Kaspersky Security Center Web Console prior to 12 & prior to 12 Patch A were vulnerable to a DLL hijacking attack that allowed an attacker to elevate privileges in the system.

Kaspersky Virus Removal Tool (KVRT) prior to 15.0.23.0 was vulnerable to arbitrary file corruption that could provide an attacker with the opportunity to eliminate content of any file in the system.

The installer of Kaspersky VPN Secure Connection prior to 5.0 was vulnerable to arbitrary file deletion that could allow an attacker to delete any file in the system.

Kaspersky Secure Connection, Kaspersky Internet Security, Kaspersky Total Security, Kaspersky Security Cloud prior to version 2020 patch E have bug that allows a local user to execute arbitrary code via execution compromised file placed by an attacker with administrator rights. No privilege escalation. Possible whitelisting bypass some of the security products

Kaspersky Anti-Virus, Kaspersky Internet Security, Kaspersky Total Security, Kaspersky Free Anti-Virus, Kaspersky Small Office Security, Kaspersky Security Cloud up to 2020, the web protection component was vulnerable to remote disclosure of various information about the user's system (like Windows version and version of the product, host unique ID). Information Disclosure.

Kaspersky Protection extension for web browser Google Chrome prior to 30.112.62.0 was vulnerable to unauthorized access to its features remotely that could lead to removing other installed extensions.

Information Disclosure in Kaspersky Anti-Virus, Kaspersky Internet Security, Kaspersky Total Security versions up to 2019 could potentially disclose unique Product ID by forcing victim to visit a specially crafted webpage (for example, via clicking phishing link). Vulnerability has CVSS v3.0 base score 2.6

Kaspersky Lab Antivirus Engine version before 04.apr.2019 has a heap-based buffer overflow vulnerability that potentially allow arbitrary code execution

Unauthorized code execution from specific DLL and is known as DLL Hijacking attack in Kaspersky Password Manager versions before 8.0.6.538.

Configuration file injection leading to Code Execution as Root in Kaspersky Secure Mail Gateway version 1.1.

Kernel pool memory corruption in one of drivers in Kaspersky Embedded Systems Security version 1.2.0.300 leads to local privilege escalation.

In Kaspersky Internet Security for Android 11.12.4.1622, some of application exports activities have weak permissions, which might be used by a malware application to get unauthorized access to the product functionality by using Android IPC.

The kluser is able to interact with the kav4fs-control binary in Kaspersky Anti-Virus for Linux File Server before Maintenance Pack 2 Critical Fix 4 (version 8.0.4.312). By abusing the quarantine read and write operations, it is possible to elevate the privileges to root.

A local denial of service vulnerability exists in window broadcast message handling functionality of Kaspersky Anti-Virus software. Sending certain unhandled window messages, an attacker can cause application termination and in the same way bypass KAV self-protection mechanism.

A denial of service vulnerability exists in the IOCTL handling functionality of Kaspersky Internet Security KL1 driver. A specially crafted IOCTL signal can cause an access violation in KL1 kernel driver resulting in local system denial of service. An attacker can run a program from user-mode to trigger this vulnerability.

Multiple information leaks exist in various IOCTL handlers of the Kaspersky Internet Security KLDISK driver. Specially crafted IOCTL requests can cause the driver to return out-of-bounds kernel memory, potentially leaking sensitive information such as privileged tokens or kernel memory addresses that may be useful in bypassing kernel mitigations. An unprivileged user can run a program from user-mode to trigger this vulnerability.

Kaspersky Safe Browser iOS before 1.7.0 does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to obtain sensitive information via a crafted certificate.
