Gibbon v22.0.00 suffers from a stored XSS vulnerability within the wall messages component.

A reflected XSS vulnerability exists in multiple pages in version 22 of the Gibbon application that allows for arbitrary execution of JavaScript (gibbonCourseClassID, gibbonPersonID, subpage, currentDate, or allStudents to index.php).

Gibbon CMS v22.0.01 was discovered to contain a cross-site scripting (XSS) vulnerability, that allows attackers to inject arbitrary script via name parameters.

Multiple cross-site scripting (XSS) vulnerabilities in the component outcomes_addProcess.php of Gibbon CMS v22.0.01 allow attackers to execute arbitrary web scripts or HTML via a crafted payload insterted into the name, category, description parameters.

Gibbon v23 does not generate a new session ID cookie after a user authenticates, making the application vulnerable to session fixation.

Gibbon v25.0.0 is vulnerable to a Local File Inclusion (LFI) where it's possible to include the content of several files present in the installation folder in the server's response.

Multiple Cross-Site Scripting (XSS) vulnerabilities have been identified in Gibbon v25.0.0, which enable attackers to execute arbitrary Javascript code.

GibbonEdu Gibbon version 25.0.1 and before allows Arbitrary File Write because rubrics_visualise_saveAjax.phps does not require authentication. The endpoint accepts the img, path, and gibbonPersonID parameters. The img parameter is expected to be a base64 encoded image. If the path parameter is set, the defined path is used as the destination folder, concatenated with the absolute path of the installation directory. The content of the img parameter is base64 decoded and written to the defined file path. This allows creation of PHP files that permit Remote Code Execution (unauthenticated).

GibbonEdu Gibbon version 25.0.0 allows HTML Injection via an IFRAME element to the Messager component.

GibbonEdu Gibbon through version 25.0.0 allows Directory Traversal via the report template builder. An attacker can create a new Asset Component. The templateFileDestination parameter can be set to an arbitrary pathname (and extension). This allows creation of PHP files outside of the uploads directory, directly in the webroot.

GibbonEdu Gibbon through version 25.0.0 allows /modules/Planner/resources_addQuick_ajaxProcess.php file upload with resultant XSS. The imageAsLinks parameter must be set to Y to return HTML code. The filename attribute of the bodyfile1 parameter is reflected in the response.

Gibbon through 26.0.00 allows /modules/School%20Admin/messengerSettings.php Server Side Template Injection leading to Remote Code Execution because input is passed to the Twig template engine (messengerSettings.php) without sanitization.

Gibbon through 26.0.00 allows remote authenticated users to conduct PHP deserialization attacks via columnOrder in a POST request to the modules/System%20Admin/import_run.php&type=externalAssessment&step=4 URI.

cross-site scripting (XSS) vulnerability in Gibbon Core v26.0.00 allows an attacker to execute arbitrary code via the imageLink parameter in the library_manage_catalog_editProcess.php component.

Cross Site Scripting vulnerability in Gibbon before v.27.0.01 and fixed in v.28.0.00 allows a remote attacker to obtain sensitive information via the email parameter found in /Gibbon/modules/User Admin/user_manage_editProcess.php.

Gibbon before 29.0.00 allows CSRF.
