The vulnerability (identified as CVE-2023-21716) has a near-perfect severity score (9.8/10) and allows remote code execution on the target device. Taking advantage of the vulnerability, hackers can deploy widespread virus infection campaigns, thereby remotely taking control of the device, collecting and encrypting data, downloading and executing other viruses.

Bkav has released a free tool to help users quickly check whether their computers have vulnerabilities or not, and provide instructions for updating the patch. Users do not need to install it but can launch it to scan at: Bkav.com.vn/Tool/CVE-2023-21716Scan. Computers using Bkav Pro do not need to run this tool because it has automatic scanning and warning features.

Mr. Nguyen Tien Dat, General Director of Bkav's Malware Research Center, said: "These types of vulnerabilities are always attractive to hackers because they exist in popular text files. Meanwhile, with devices that do not have automatic update mode enabled, updating patches is not simple, not everyone can do it."
