It is advisable to upgrade the affected component.

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

The password reset function in ILIAS 7.0beta1 through 7.20 and 8.0beta1 through 8.1 allows remote attackers to take over the account.

ILIAS before versions 9.22, 10.10, and 11.3 contains an unauthenticated PHP object injection vulnerability that allows unauthenticated attackers to execute arbitrary code by injecting serialized objects through the LTI authentication endpoint and triggering deserialization via the Shibboleth back-channel logout endpoint. Attackers can write arbitrary serialized objects into session storage, then exploit an available POP gadget through the logout endpoint's unrestricted deserialization to write attacker-controlled PHP content to a web-accessible path and achieve remote code execution as the web server user.

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.

ILIAS before 9.24, 10.12, and 11.5 contains an unrestricted file upload vulnerability in QTI question import image handling (ilQtiMatImageSecurity) that allows authenticated authors to write executable files. Attackers with question pool import rights can import a crafted archive writing a .htaccess and PHP file to the web-served image directory, achieving remote code execution as the web server user.

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 before 9.24, 10.x before 10.12 and 11.x before 11.5 contains an argument injection vulnerability in assImagemapQuestionGUI that allows question authors to inject ImageMagick convert options via uploaded image filenames. Attackers can embed tab-separated options, which escapeshellcmd() does not neutralise, to write a PHP file under the web root and achieve remote code execution.

The Learning Module in ILIAS 7.25 (2023-09-12 release) allows an attacker (with basic user privileges) to achieve a high-impact Directory Traversal attack on confidentiality and availability. By exploiting this network-based vulnerability, the attacker can move specified directories, normally outside the documentRoot, to a publicly accessible location via the PHP function rename(). This results in a total loss of confidentiality, exposing sensitive resources, and potentially denying access to the affected component and the operating system's components. To exploit this, an attacker must manipulate a POST request during the creation of an exercise unit, by modifying the oldname and newname parameters via directory traversal. However, it's essential to note that, when exploiting this vulnerability, the specified directory will be relocated from its original location, rendering all files obtained from there unavailable.

SQL injection vulnerability in repository.php in ILIAS 3.7.4 and earlier allows remote attackers to execute arbitrary SQL commands via the refid parameter.

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 via a malicious BPMN2 workflow definition file.

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.

ILIAS before versions 9.22, 10.10, and 11.3 contains an arbitrary file read vulnerability in the SOAP addFile method that allows authenticated users to read server files by supplying crafted XML with COPY-mode imports. Attackers can construct absolute file paths through an unsandboxed import directory and retrieve sensitive files including configuration files containing database credentials and setup passwords.

ILIAS Learning Management System 4.3 contains a server-side request forgery vulnerability that allows attackers to read local files through portfolio PDF export functionality. Attackers can inject a script that uses XMLHttpRequest to retrieve local file contents when the portfolio is exported to PDF.

ILIAS 4.4.1 allows remote attackers to execute arbitrary PHP code via an e-mail attachment that leads to creation of a .php file with a certain clientid pathname.

Unrestricted file upload vulnerability in ilias.php in ILIAS 4.4.1 allows remote authenticated users to execute arbitrary PHP code by using a .php filename in an uploadfiles action to the uploadFiles command, and then accessing the .php file via a direct request to a certain clientid pathname.

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 before 5.2.3 has XSS via SVG documents.

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.
