Vulnerability Details

Apache OFBiz has unsafe deserialization prior to version 17.12.06. An unauthenticated attacker can exploit this vulnerability to take over Apache OFBiz.

The CVSS score is 9.8, classified as critical, indicating that the vulnerability is highly dangerous and can lead to significant impacts, including high confidentiality, integrity, and availability impacts.

The CWE classification for this vulnerability is CWE-502, indicating issues related to deserialization of untrusted data.

Technical Analysis

The root cause of this vulnerability is improper handling of deserialization processes within Apache OFBiz, allowing attackers to send crafted data that can manipulate the control flow of the application.

The attack vector for this vulnerability is network-based, meaning that an attacker does not require physical access to the system to exploit it. The attack complexity is low, and no privileges or user interaction are required for exploitation.

The vulnerability has a high impact on confidentiality, integrity, and availability, which means that successful exploitation could lead to unauthorized data access, modification of data, and denial of service.

Risk & Impact Analysis

Real-world deployment of Apache OFBiz with this vulnerability exposes organizations to severe risks of unauthorized access and data breaches. Attackers may leverage this vulnerability to gain control over sensitive business operations and data.

The blast radius potential is significant, as successful exploitation can affect the entire application, leading to full control over the system. Given the CVSS score and the fact that exploits are available, organizations should address this issue in their priority patch cycle.
