Exploits

Overview

A vulnerability is a weakness that can be exploited by a threat actor, such as an attacker, to perform unauthorized actions within a computer system. Attackers exploit vulnerabilities to obtain rights, steal sensitive data, or sabotage software and hardware systems.

Suggestion

If an exploit is detected, handle the threat by following the instructions in Table 1.

**Table 1** Suggestions for handling exploits
Threat Alarm	Severity	Threat Description	Suggestion
MySQL exploit	Low	If SA detects that an ECS instance is attacked using the MySQL vulnerability, the ECS instance is attacked using the MySQL vulnerability.	The main cause of the attack is that the MySQL service is enabled on the public network for the ECS instance. Therefore, you are advised to perform the following operations: Configure security group rules and forbid the MySQL service from accessing the public network. Unbind the ELB, and disable the MySQL service from accessing the public network.
Redis exploit	Low	If SA detects that an ECS instance is attacked using the Redis vulnerability, the ECS instance is attacked using the Redis vulnerability.	The main cause of the attack is that the Redis service is enabled on the public network for the ECS instance. Therefore, you are advised to perform the following operations: Configure security group rules and forbid the Redis service from accessing the public network. Unbind the ELB, and disable the Redis service from accessing the public network.
