An unauthenticated arbitrary file upload vulnerability exists in Havalite CMS version 1.1.7 (and possibly earlier) in the upload.php script. The application fails to enforce proper file extension validation and authentication checks, allowing remote attackers to upload malicious PHP files via a crafted multipart/form-data POST request. Once uploaded, the attacker can access the file directly under havalite/tmp/files/, resulting in remote code execution.

Havalite CMS 1.1.7 has a stored XSS vulnerability

Multiple cross-site scripting (XSS) vulnerabilities in Havalite 1.0.4 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) find or (2) replace fields to havalite/findReplace.php; (3) username parameter to havalite/havalogin.php, (4) the Edit Article module, or (5) havapost.php in the postAuthor module; (6) postId parameter to havapost.php; (7) userId parameter to havauser.php; or (8) linkId parameter to havalink.php.

Havalite CMS 1.1.0 and earlier stores sensitive information under the web root with insufficient access control, which allows remote attackers to download the configuration database via a direct request for data/havalite.db3.

Unrestricted file upload vulnerability in havaupload.php in Havalite CMS 1.1.0 and earlier allows remote attackers to execute arbitrary code by uploading a file with a .php;.gif extension, then accessing it via a direct request to the file in tmp/files/.

SQL injection vulnerability in havapost.php in Havalite CMS 1.1.0 and earlier allows remote attackers to execute arbitrary SQL commands via the postId parameter.
