Cross-site scripting (XSS) vulnerability in the author page (prive/formulaires/editer_auteur.php) in SPIP before 2.1.24 and 3.0.x before 3.0.12 allows remote attackers to inject arbitrary web script or HTML via the url_site parameter.

The Security Screen (_core_/securite/ecran_securite.php) before 1.1.8 for SPIP, as used in SPIP 3.0.x before 3.0.12, allows remote attackers to execute arbitrary PHP via the connect parameter.

SPIP 3.0.x before 3.0.9, 2.1.x before 2.1.22, and 2.0.x before 2.0.23 allows remote attackers to gain privileges and "take editorial control" via vectors related to ecrire/inc/filtres.php.

Multiple cross-site scripting (XSS) vulnerabilities in SPIP 1.9.x before 1.9.2.o, 2.0.x before 2.0.18, and 2.1.x before 2.1.13 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Multiple unspecified vulnerabilities in SPIP before 1.9.2.o, 2.0.x before 2.0.18, and 2.1.x before 2.1.13 have unknown impact and attack vectors that are not related to cross-site scripting (XSS), different vulnerabilities than CVE-2012-2151.

SPIP 1.9 before 1.9.2i and 2.0.x through 2.0.8 does not use proper access control for (1) ecrire/exec/install.php and (2) ecrire/index.php, which allows remote attackers to conduct unauthorized activities related to installation and backups, as exploited in the wild in August 2009.

SQL injection vulnerability in inc/rubriques.php in SPIP 1.8 before 1.8.3b, 1.9 before 1.9.2g, and 2.0 before 2.0.2 allows remote attackers to execute arbitrary SQL commands via the ID parameter. NOTE: some of these details are obtained from third party information.

Multiple unspecified vulnerabilities in SPIP 1.8 before 1.8.3b, 1.9 before 1.9.2g, and 2.0 before 2.0.2 have unknown impact and attack vectors.

PHP remote file inclusion vulnerability in inc-calcul.php3 in SPIP 1.7.2 allows remote attackers to execute arbitrary PHP code via a URL in the squelette_cache parameter, a different vector than CVE-2006-1702. NOTE: this issue has been disputed by third party researchers, stating that the squelette_cache variable is initialized before use, and is only used within the scope of a function

PHP remote file inclusion vulnerability in spip_login.php3 in SPIP 1.8.3 allows remote attackers to execute arbitrary PHP code via a URL in the url parameter.
