The Standard Remember method in TikiWiki CMS/Groupware 3.x before 3.5 allows remote attackers to bypass access restrictions related to "persistent login," probably due to the generation of predictable cookies based on the IP address and User agent in userslib.php.

SQL injection vulnerability in the find function in searchlib.php in TikiWiki CMS/Groupware 3.x before 3.5 allows remote attackers to execute arbitrary SQL commands via the $searchDate variable.

Cross-site scripting (XSS) vulnerability in tiki-cookie-jar.php in TikiWiki CMS/Groupware before 8.2 and LTS before 6.5 allows remote attackers to inject arbitrary web script or HTML via arbitrary parameters.

TikiWiki CMS/Groupware 8.3 and earlier allows remote attackers to obtain the installation path via a direct request to (1) admin/includecalendar.php, (2) tiki-rsserror.php, or (3) tiki-watershedservice.php.

TikiWiki CMS/Groupware before 6.7 LTS and before 8.4 allows remote attackers to execute arbitrary PHP code via a crafted serialized object in the (1) cookieName to lib/banners/bannerlib.php; (2) printpages or (3) printstructures parameter to (a) tiki-printmultipages.php or (b) tiki-printpages.php; or (4) sendpages, (5) sendstructures, or (6) sendarticles parameter to tiki-sendobjects.php, which is not properly handled when processed by the unserialize function.
