Multiple Unix rpc.walld Message Spoofing
Local Access Required Denial of Service, Input Manipulation
Loss of Confidentiality, Loss of Availability
Exploit Public

- 漏洞描述

The Unix daemon rpc.walld contains a flaw that may allow a malicious user to conduct social engineering attacks via spoofed messages. The issue is triggered when a user sends a message via the service, which checks to see if the message is being sent from a local or a remote user by examining whether stderr corresponds to a tty; if it does not, the program checks to see if the first five bytes of the message are "From:", and uses that string as the user from which the message will appear to have been sent. Thus, if a local user simply closes stderr and then sends their message, they can supply any username for the From: field, effectively allowing message spoofing that could result in a loss of integrity. If enough of these messages are sent in quick succession, a denial of service can be performed by filling users' screens and not allowing them to interact with the system.
