FreeBSD Sysinstall Anonymous FTP Misconfiguration

Loss of Integrity
Exploit Public

- 漏洞描述

FreeBSD contains a flaw that may allow a malicious user to access the platform. The issue is triggered when a malicious user logs onto the victim system using a passwordless account "ftp" that is automatically created by sysinstall, while an authorized user is running the sysinstall utility. It is possible that the flaw may allow shell access (via /bin/date) resulting in a loss of integrity.

It is possible to correct the flaw by implementing the following workaround: use the vipw command to change "ftp::" to "ftp:*:" and the shell from "/bin/date" to "/nonexistent". Also, FreeBSD has released a patch.
