CVE-2020-7817

Vulnerability

The vulnerability resides in the MyBrowserPlus software, which downloads necessary files via a setup file (Setup.inf) without performing sufficient integrity verification. This allows an attacker to replace legitimate files with arbitrary content during the download process. The affected versions are not specified in the available references.

Exploitation

An attacker must be in a position to intercept or manipulate network traffic between the MyBrowserPlus installer and the download server (e.g., man-in-the-middle). By serving a malicious file instead of the intended one, the attacker can exploit the lack of integrity checks to deliver arbitrary content.

Impact

Successful exploitation could lead to arbitrary file download and execution on the victim's system, potentially resulting in remote code execution or installation of malware.

Mitigation

No official fix or patch has been disclosed in the available references. Users should avoid using MyBrowserPlus until a security update is released. The vendor's website appears to be unavailable.
