An issue was discovered in ILIAS 6.23, 7 before 7.22, and 8.1. An attacker can execute arbitrary code via ZIP upload.

A security flaw has been discovered in ILIAS up to 9.21/10.9/11.2. This affects the function ilObjMediaObjectGUI::uploadMultipleSubtitleFileObject of the file Services/Repository/Service/Resources/ZipAdapter.php of the component MediaPool. The manipulation results in unrestricted upload. The attack may be launched remotely. Upgrading to version 9.22, 10.10 and 11.3 is able to mitigate this issue. The patch is identified as ef5d7f99fe1ea0381db04b333a2906548b3590e4/b0d61be43671b6bfe91baf469a5ee11e764f2e23. It is recommended to upgrade the affected component.

A vulnerability was identified in ILIAS Learning Management System 11.0. This issue affects the function ilTrQuery::executeQueries of the file components/ILIAS/Tracking/classes/class.ilTrQuery.php of the component Learning Progress Tracking. Such manipulation of the argument trouptablenav leads to sql injection. It is possible to launch the attack remotely. The exploit is publicly available and might be used. It is suggested to upgrade the affected component. This issue was independently identified and fixed internally by the vendor's own security team ahead of this report.

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.

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.

A Stored Cross-site Scripting (XSS) vulnerability in the "Import of organizational units and title of organizational unit" feature in ILIAS 7.20 to 7.29 and ILIAS 8.4 to 8.10 as well as ILIAS 9.0 allows remote authenticated attackers with administrative privileges to inject arbitrary web script or HTML via XML file upload.

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.

A vulnerability has been found in ILIAS up to 8.23/9.13/10.1. This affects the function unserialize of the component Base64 Decoding Handler. Such manipulation of the argument fsettings leads to deserialization. It is possible to launch the attack remotely. Upgrading to version 8.24, 9.14 and 10.2 is able to mitigate this issue. It is advisable to upgrade the affected component.

A flaw has been found in ILIAS up to 8.23/9.13/10.1. Affected by this issue is the function unserialize of the component Test Import. This manipulation causes deserialization. It is possible to initiate the attack remotely. Upgrading to version 8.24, 9.14 and 10.2 can resolve this issue. Upgrading the affected component is advised.

A vulnerability was detected in ILIAS up to 8.23/9.13/10.1. Affected by this vulnerability is an unknown functionality of the component Certificate Import Handler.
