Vulnerability Details
This vulnerability allows exploitation through missing authorization controls in the User Sync ActiveCampaign plugin. The CVSS score of 5.4 reflects a medium severity level, indicating that while it is not critical, it still warrants attention.
The affected product, User Sync ActiveCampaign, is vulnerable from n/a through version 1.3.2. The vulnerability is classified under CWE-862, which pertains to missing authorization.
Technical Analysis
The root cause of this vulnerability lies in the improper configuration of access control mechanisms, which can allow unauthorized users to gain access to functionalities that should be restricted. The attack vector is primarily network-based, with low complexity and low privileges required for exploitation. User interaction is not necessary, making it easier for attackers to exploit this vulnerability.
The confidentiality impact is rated as none, while the integrity and availability impacts are both rated as low. This means that while data may not be directly compromised, unauthorized changes to data could still occur.
Risk & Impact Analysis
The risk to organizations includes potential unauthorized access to user data, which could lead to further exploitation or data manipulation. The blast radius of this vulnerability could extend to all users of the plugin, creating a significant impact on organizations that rely on this component.
Given the current CVSS score and the lack of known exploits, organizations should address this vulnerability as part of their routine security measures. While it may not be actively exploited, its presence could signal a broader issue with access controls that could be exploited in the future.
