Status: ModifiedMedium (6.5)—

The TCLHTTPd service in Lyris ListManager before 8.9b allows remote attackers to obtain source code for arbitrary .tml (TCL) files via (1) a request with a trailing null byte (%00), which might also require (2) an authentication bypass step that involves a username with a trailing "@" characters.

CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:S/C:P/I:P/A:P
