SQL injection vulnerability in main_content.asp in Acidcat 2.1.13 and earlier allows remote attackers to execute arbitrary SQL commands via the ID parameter to default.asp.

Acidcat 2.1.13 and earlier stores the database under the web root with insufficient access control, which allows remote attackers to obtain sensitive information via a request to databases/acidcat.mdb.

Acidcat CMS 3.5.x does not prevent access to install.asp after installation finishes, which might allow remote attackers to restart the installation process and have unspecified other impact via requests to install.asp and other install_*.asp scripts. NOTE: the final installation screen states "Important: you must now delete all files beginning with 'install' from the root directory."

Acidcat CMS 3.5.3 and earlier stores sensitive information under the web root with insufficient access control, which allows remote attackers to download a database containing credentials via a direct request for databases/acidcat_3.mdb.

Multiple cross-site scripting (XSS) vulnerabilities in Acidcat CMS 3.5.1, 3.5.2, 3.5.6, and possibly earlier allow remote attackers to inject arbitrary web script or HTML via the PATH_INFO to (1) admin_colors.asp, (2) admin_config.asp, and (3) admin_cat_add.asp in admin/.
