SB2021020111 - Multiple vulnerabilities in Accfly Wireless Security IR Camera System 720P

Description

This security bulletin contains information about 4 secuirty vulnerabilities.

1) Heap-based buffer overflow (CVE-ID: CVE-2020-25782)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in the "CNetClientManage::ServerIP_Proto_Set" function. A remote attacker can pass specially crafted data to the application, trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

2) Heap-based buffer overflow (CVE-ID: CVE-2020-25783)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in the "CNetClientTalk::OprMsg" function. A remote attacker can pass specially crafted data to the application, trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

3) Stack-based buffer overflow (CVE-ID: CVE-2020-25784)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in the "CNetClientGuard::SubOprMsg" function. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

4) Stack-based buffer overflow (CVE-ID: CVE-2020-25785)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in the "CFtpProtocol::FtpLogin" function. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
