CVE-2006-1279 (2006-03-19)

CGI::Session 4.03-1 allows local users to overwrite arbitrary files via a symlink attack on temporary files used by (1) Driver::File, (2) Driver::db_file, and possibly (3) Driver::sqlite.

possible SQL injection attack

CVE-2026-56016 (2026-07-01)

CGI::Session::ID::md5 versions before 4.49 for Perl generate predictable session ids from low-entropy sources. The generate_id method builds the session id from a MD5 digest of the process id, the epoch time, and the built-in rand() function. All three are predictable, low-entropy sources: the PID is drawn from a small range, the epoch time can be guessed or read from the HTTP Date header, and Perl's rand() is unsuitable for security purposes because it is predictable and reversible. An attacker who predicts a session id can impersonate the corresponding session and bypass authentication.

NAME

CGI::Session::Driver::mysql - CGI::Session driver for MySQL database

SYNOPSIS

$s = new CGI::Session( "driver:mysql", $sid);
$s = new CGI::Session( "driver:mysql", $sid, { DataSource  => 'dbi:mysql:test',
                                               User        => 'sherzodr',
                                               Password    => 'hello' });
$s = new CGI::Session( "driver:mysql", $sid, { Handle => $dbh } );

DESCRIPTION

mysql stores session records in a MySQL table. For details see CGI::Session::Driver::DBI, its parent class.

DRIVER ARGUMENTS

mysql driver supports all the arguments documented in CGI::Session::Driver::DBI. In addition, DataSource argument can optionally leave leading "dbi:mysql:" string out:

$s = new CGI::Session( "driver:mysql", $sid, {DataSource=>'shopping_cart'});
# is the same as:
$s = new CGI::Session( "driver:mysql", $sid, {DataSource=>'dbi:mysql:shopping_cart'});
