Laravel Ignition File Upload Vulnerability
Laravel Ignition contains a file upload vulnerability that allows unauthenticated remote attackers to execute malicious code due to insecure usage of file_get_contents() and file_put_contents().
A remote attacker, without authentication, can achieve full data confidentiality loss, arbitrary modification of data, complete denial of service or system unavailability. CISA has confirmed use of this vulnerability in known ransomware campaigns — treat as high priority for remediation. Federal agencies are required to remediate by 2023-10-09 under CISA BOD 22-01.
This vulnerability affects Laravel Ignition. Ignition before 2.5.2, as used in Laravel and other products, allows unauthenticated remote attackers to execute arbitrary code because of insecure usage of file_get_contents() and file_put_contents(). This is exploitable on sites using debug mode with Laravel before 8.4.2. Exploitation requires remote network access, low attack complexity, no authentication required, and no user interaction required.
