The scope of what files are vulnerable will depend on the permissions given to the running flarum process.

For example, an attacker could use the following code to read the contents of the `/etc/passwd` file on a linux machine. An attacker can achieve this by providing an absolute path to a sensitive file in the custom `LESS` setting, which the `LESS` parser will then read. In versions prior to 1.7.0 an admin account which has already been compromised by an attacker may use a vulnerability in the `LESS` parser which can be exploited to read sensitive files on the server through the use of path traversal techniques. There are no known workarounds.įlarum is a forum software package for building communities. After upgrading, all users’ hashed passwords should be updated (saved to the database). Upgrade to Shield v1.0.0-beta.4 or later to fix this issue. If an attacker gets (1) the user's hashed password by Shield, and (2) the hashed password (SHA-384 hash without salt) from somewhere, the attacker may easily crack the user's password. Therefore, they should be removed as soon as possible.

All hashed passwords stored in Shield v1.0.0-beta.3 or earlier are easier to crack than expected due to the vulnerability. An improper implementation was found in the password storage process. NOTE: the vendor's position is that 'Auto-fill on page load' is not enabled by default.ĬodeIgniter Shield provides authentication and authorization for the CodeIgniter 4 PHP framework. ** DISPUTED ** Bitwarden through 2023.2.1 offers password auto-fill when the second-level domain matches, e.g., a password stored for an hosting provider when is visited.
