Assigner: MITRE

Description

e107 CMS thru 2.3.3 are vulnerable to insecure deserialization in the `install.php` script. The script processes user-controlled input in the `previous_steps` POST parameter using `unserialize(base64_decode())` without validation, allowing attackers to craft malicious serialized data. This could lead to remote code execution, arbitrary file operations, or denial of service, depending on available PHP object gadgets in the codebase.

Attack-Flow Graph

Executive Summary

This vulnerability exists in e107 CMS versions up to 2.3.3 in the install.php script. It involves insecure deserialization where the script unserializes user-controlled input from the previous_steps POST parameter without validation. Attackers can exploit this by crafting malicious serialized data, potentially leading to remote code execution, arbitrary file operations, or denial of service.

Impact Analysis

The vulnerability can allow attackers to execute remote code on the server, perform arbitrary file operations, or cause denial of service. This can compromise the security and availability of the affected system.
