Multiple eval injection vulnerabilities in HiveMail 1.3 and earlier allow remote attackers to execute arbitrary PHP code via (1) the contactgroupid parameter in addressbook.update.php, (2) the messageid parameter in addressbook.add.php, (3) the folderid parameter in folders.update.php, and possibly certain parameters in (4) calendar.event.php, (5) index.php, (6) pop.download.php, (7) read.bounce.php, (8) rules.block.php, (9) language.php, and (10) certain other scripts, as demonstrated by an addressbook.update.php request with a contactgroupid value of phpinfo() preceded by facilitators.
