A vulnerability in Node.js could allow an unauthenticated, remote attacker to bypass security restrictions and access sensitive information on a targeted system.
The Node.js Foundation has confirmed the vulnerability and released software updates.
To exploit this vulnerability, an attacker may need access to the same internal, trusted network in which the targeted system may reside. This access requirement may reduce the likelihood of a successful exploit.
Administrators are advised to apply the appropriate updates.
Administrators are advised to allow only trusted users to have network access.
Administrators are advised to run both firewall and antivirus applications to minimize the potential of inbound and outbound threats.
Administrators may consider using IP-based access control lists (ACLs) to allow only trusted systems to access the affected systems.
Administrators can help protect affected systems from external attacks by using a solid firewall strategy.
Administrators are advised to monitor affected systems.
