Background
phpbb3 is an open-source forum software package written in PHP. It provides a platform for users to create and manage online communities. The package includes various features such as user registration, discussion boards, private messaging, and administration control panel. However, phpbb3 is susceptible to multiple vulnerabilities that could be exploited by attackers to perform cross-site request forgery (CSRF) attacks and session hijacking.
Vulnerability Detail
The first vulnerability, identified as CVE-2019-16993, exists in the BBCode page of the Administration Control Panel. The page lacks proper verification of a CSRF token, allowing an attacker to execute a CSRF attack if they can obtain the session ID of a reauthenticated administrator. This vulnerability could lead to unauthorized actions being performed by the attacker.
The second vulnerability, known as CVE-2019-13776, involves the Remote Avatar feature in phpbb3. By leveraging CSRF, an attacker can steal an Administration Control Panel session ID, leading to stored cross-site scripting (XSS) attacks. This vulnerability could enable an attacker to inject malicious code into the forum and potentially compromise user data.
