A vulnerability in Eclipse Jetty could allow an unauthenticated, remote attacker to access sensitive information on a targeted system.
The vulnerability exists because the affected software improperly handles queries that do not match the dynamic URL pattern for webapps that use default error handling settings. An attacker could exploit this vulnerability by sending a query that submits malicious input to a targeted system. A successful exploit could trigger a java.nio.file.InvalidPathException message, which could allow the attacker to view sensitive information, such as the software installation path.
Eclipse has confirmed the vulnerability and released software updates.
To exploit this vulnerability, the attacker must send a query that submits malicious input to the targeted system, making exploitation more difficult in environments that restrict network access from untrusted sources.
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.
