In ILIAS through 7.10, lack of verification when changing an email address (on the Profile Page) allows remote attackers to take over accounts.

ILIAS 7.25 (2023-09-12) allows any authenticated user to execute arbitrary operating system commands remotely, when a highly privileged account accesses an XSS payload. The injected commands are executed via the exec() function in the execQuoted() method of the ilUtil class (/Services/Utilities/classes/class.ilUtil.php) This allows attackers to inject malicious commands into the system, potentially compromising the integrity, confidentiality, and availability of the ILIAS installation and the underlying operating system.

Remote Code Execution can occur via the external news feed in ILIAS 6.4 because of incorrect parameter sanitization for Magpie RSS data.

A local file inclusion vulnerability in ILIAS before 5.3.19, 5.4.10 and 6.0 allows remote authenticated attackers to execute arbitrary code via the import of personal data.

ILIAS before 7.16 allows OS Command Injection.

ILIAS 7 before 7.30 and ILIAS 8 before 8.11 as well as ILIAS 9.0 allow remote authenticated attackers with administrative privileges to execute operating system commands via file uploads with dangerous types.

The workflow-engine of ILIAS before 7.23 and 8 before 8.3 allows remote authenticated users to run arbitrary system commands on the application server as the application user by uploading a workflow definition file with a malicious filename.

A Stored Cross-site Scripting (XSS) vulnerability in the "Import of user role and title of user role" feature in ILIAS 7 before 7.30 and ILIAS 8 before 8.11 allows remote authenticated attackers with administrative privileges to inject arbitrary web script or HTML via XML file upload.

An information disclosure vulnerability in ILIAS before 5.3.19, 5.4.12 and 6.0 allows remote authenticated attackers to get the upload data path via a workspace upload.

ILIAS before 7.16 allows External Control of File Name or Path.

ILIAS (2013-09-12 release) contains a medium-criticality Directory Traversal local file inclusion vulnerability in the ScormAicc module. An attacker with a privileged account, typically holding the tutor role, can exploit this to gain unauthorized access to and potentially retrieve confidential files stored on the web server. The attacker can access files that are readable by the web server user www-data; this may include sensitive configuration files and documents located outside the documentRoot. The vulnerability is exploited by an attacker who manipulates the file parameter in a URL, inserting directory traversal sequences in order to access unauthorized files. This manipulation allows the attacker to retrieve sensitive files, such as /etc/passwd, potentially compromising the system's security. This issue poses a significant risk to confidentiality and is remotely exploitable over the internet.

Ilias 5.3 before 5.3.12; 5.2 before 5.2.21 is affected by: Cross Site Scripting (XSS) - CWE-79 Type 2: Stored XSS (or Persistent). The impact is: Execute code in the victim's browser. The component is: Assessment / TestQuestionPool. The attack vector is: Cloze Test Text gap (attacker) / Corrections view (victim). The fixed version is: 5.3.12.

ILIAS before 5.1.26, 5.2.x before 5.2.15, and 5.3.x before 5.3.4, due to inconsistencies in parameter handling, is vulnerable to various instances of reflected cross-site-scripting.

The RSS subsystem in ILIAS 5.1.x, 5.2.x, and 5.3.x before 5.3.5 has XSS via a URI to Services/Feeds/classes/class.ilExternalFeedItem.php.

Services/Feeds/classes/class.ilExternalFeedItem.php in ILIAS 5.1.x, 5.2.x, and 5.3.x before 5.3.5 has XSS via a link attribute.

ILIAS 5.1.x, 5.2.x, and 5.3.x before 5.3.5 redirects a logged-in user to a third-party site via the returntourl parameter.

Services/COPage/classes/class.ilPCSourceCode.php in ILIAS 5.1.x, 5.2.x, and 5.3.x before 5.3.5 has XSS.

ILIAS 5.3.4 has XSS through unsanitized output of PHPSELF, related to shiblogout.php and third-party demo files.

error.php in ILIAS 5.2.x through 5.3.x before 5.3.4 allows XSS via the text of a PDO exception.

Services/Form/classes/class.ilDateDurationInputGUI.php and Services/Form/classes/class.ilDateTimeInputGUI.php in ILIAS 5.1.x through 5.3.x before 5.3.4 allow XSS via an invalid date.

ILIAS before 7.16 has an Open Redirect.

A Stored Cross-site Scripting (XSS) vulnerability in the "Import of Users and login name of user" feature in ILIAS 7 before 7.30 and ILIAS 8 before 8.11 allows remote authenticated attackers with administrative privileges to inject arbitrary web script or HTML via XML file upload.

Stored XSS vulnerability in the Media Objects component of ILIAS before 5.1.21 and 5.2.x before 5.2.9 allows an authenticated user to inject JavaScript to gain administrator privileges, related to the setParameter function in Services/MediaObjects/classes/class.ilMediaItem.php.

An XSS issue exists in the question-pool file-upload preview feature in ILIAS 6.4.

ILIAS before 7.16 allows XSS.

A Stored Cross-site Scripting (XSS) vulnerability in ILIAS 7 before 7.30 and ILIAS 8 before 8.11 allows remote authenticated attackers with tutor privileges to inject arbitrary web script or HTML via XML file upload.
