Bug vulnerability class | Wrong File Permission |
Bug description | The target system seems to be running a vulnerable old finger daemon. A special query beginning with a pipe sends the content of a file back. An attacker can read any file on the target system with commands like "finger |/etc/passwd@target". |
Bug solution | The finger service, if not needed, should be disabled (in /etc/inetd.conf) or if possible firewalled. Upgrade to the latest software version to be not vulnerable anymore. |
