The vulnerability was published on May 25, 2022, and has since been modified, indicating ongoing developments in its exploitation or remediation status. This vulnerability serves as a reminder of the importance of maintaining robust security practices for API endpoints.
Vulnerability Details
An improper authentication vulnerability exists in the REST API functionality of Open Automation Software OAS Platform V16.00.0121. A specially-crafted series of HTTP requests can lead to unauthenticated use of the REST API. An attacker can send a series of HTTP requests to trigger this vulnerability.
The CVSS score of 9.4 indicates a critical severity level, characterized by a low attack complexity, no required privileges, and no user interaction needed for exploitation. The potential impacts include low confidentiality, high integrity, and high availability impacts, emphasizing the critical need for immediate remediation.
Affected products include the OAS Platform, specifically version 16.00.0112 and later, as identified by the CVE-2022-26833 classification. The vulnerability has been assigned CWE-306, which corresponds to improper authentication.
Technical Analysis
The root cause of this vulnerability is associated with the improper handling of authentication within the REST API functionality. Attackers may leverage this vulnerability by crafting specific HTTP requests that bypass authentication checks. The attack vector is network-based, allowing exploitation from any location without needing physical access to the affected system.
The attack complexity is low, as it does not require any specific conditions or privileges to be in place. Additionally, no user interaction is required, which means that the potential for automated attacks is high. The vulnerability impacts confidentiality minimally but can severely compromise integrity and availability, making it critical for organizations to address.
Risk & Impact Analysis
Real-world deployment of the affected OAS Platform presents significant risks, particularly as it pertains to unauthorized access to sensitive operations and data. The blast radius of this vulnerability is extensive, potentially affecting all users of the OAS Platform version 16.00.0121. Organizations must recognize that the exploitation of this vulnerability could lead to unauthorized data disclosure, alteration, or service disruption.
The urgency for remediation is underscored by the high CVSS score and the potential for attackers to exploit this vulnerability easily. Organizations should address this vulnerability in their priority patch cycle to mitigate risks effectively.
