Attack-Flow Graph

Executive Summary

This vulnerability exists in the ILIAS software up to versions 8.23, 9.13, and 10.1, specifically in the Base64 Decoding Handler's unserialize function. An attacker can manipulate the argument 'f_settings' to trigger unsafe deserialization, which can be exploited remotely. This can lead to unintended code execution or other malicious actions. Upgrading to versions 8.24, 9.14, or 10.2 mitigates the issue.

Impact Analysis

Exploitation of this vulnerability can allow an attacker to remotely execute malicious code or perform unauthorized actions within the affected system due to unsafe deserialization. This can compromise the confidentiality, integrity, and availability of the system and its data.

Mitigation Strategies

The immediate step to mitigate this vulnerability is to upgrade the affected ILIAS component to version 8.24, 9.14, or 10.2, as these versions address the issue.
