Sites WordPress in Alert: A Vulnerability in WP Fastest Cache Plugin Exposes 600,000 Sites to Risk
Cybersecurity is an issue always warm for those who own and manage a website, especially when it comes to popular platforms such as WordPress. It has recently emerged that WP Fastest Cache, one of the most popular plugins to optimize page loading speed and improve ranking SEO, presents a serious SQL injection vulnerability. This security flaw could allow attackers di guadagnare l’accesso non autorizzato al database del sito, con potenziali conseguenze devastanti.
SQL injection vulnerabilities are among the most insidious cyber threats, as they allow hackers to inject malicious code nelle query SQL, permettendo l’accesso a informazioni riservate o addirittura l’esecuzione di comandi a distanza. Secondo i dati forniti da WordPress.org, WP Fastest Cache è attualmente utilizzato da oltre un milione di siti, ma più di 600.000 tra questi rischiano attacchi a causa dell’uso di una vulnerable version Of the plugin.
The WPScan security team of Automatic discovered and catalogued this vulnerability with the code CVE-2023-6063, attribuendole un livello di gravità pari a 8.6 su 10. L’elemento critico si trova nella funzione “is_user_admin” della classe “WpFastestCacheCreateCache”, che dovrebbe controllare se un utente è amministratore basandosi su un valore estratto dai cookie. Tuttavia, a causa di una gestione non adeguata dell’input, gli attaccanti possono manipolare questa verifica per alterare le query SQL eseguite dal plugin.
WordPress databases, containing user data, passwords, configurations and other vital information, represent a precious booty per gli hacker. L’imminente pubblicazione di un proof-of-concept by WPScan on November 27 raises additional concerns, although the not particularly complex nature of the vulnerability suggests that some malicious parties may have already begun to exploit it.
In response to this troubling scenario, the developers of WP Fastest Cache promptly released the 1.2.2 del plugin, che risolve il problema di sicurezza. Aggiornare il plugin è quindi un’azione strongly recommended for all users to protect their sites from potential attacks.
