CVE-2011-0633 (2011-01-20)

The Net::HTTPS module in libwww-perl (LWP) before 6.00, as used in WWW::Mechanize, LWP::UserAgent, and other products, when running in environments that do not set the If-SSL-Cert-Subject header, does not enable full validation of SSL certificates by default, which allows remote attackers to spoof servers via man-in-the-middle (MITM) attacks involving hostnames that are not properly validated.

LWP::Protocol::file can open existent file from file:// scheme. However, current version of LWP uses open FILEHANDLE,EXPR and it has ability to execute arbitrary command

NAME

WWW::RobotRules::AnyDBM_File - Persistent RobotRules

SYNOPSIS

require WWW::RobotRules::AnyDBM_File;
require LWP::RobotUA;

# Create a robot useragent that uses a diskcaching RobotRules
my $rules = WWW::RobotRules::AnyDBM_File->new( 'my-robot/1.0', 'cachefile' );
my $ua = WWW::RobotUA->new( 'my-robot/1.0', 'me@foo.com', $rules );

# Then just use $ua as usual
$res = $ua->request($req);

DESCRIPTION

This is a subclass of WWW::RobotRules that uses the AnyDBM_File package to implement persistent diskcaching of robots.txt and host visit information.

The constructor (the new() method) takes an extra argument specifying the name of the DBM file to use. If the DBM file already exists, then you can specify undef as agent name as the name can be obtained from the DBM database.
