Vulnerability Details
The vulnerability described in CVE-2021-20359 pertains to the IBM Cloud Pak for Automation, specifically in versions 20.0.3 and 20.0.2-IF002. The log files generated by the Business Automation Application Designer Component potentially contain sensitive information, which could be accessed by unauthorized users. This falls under the CWE-532 classification, indicating improper storage of sensitive information.
The CVSS 3.1 vector for this vulnerability is AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N, reflecting a network attack vector, low attack complexity, and low privileges required for exploitation. The overall impact on confidentiality is high, while integrity and availability impacts are none.
Technical Analysis
The root cause of CVE-2021-20359 is related to the logging mechanism within the IBM Cloud Pak for Automation. The application stores sensitive information in log files without adequate access controls, making this data susceptible to unauthorized access.
The attack vector is primarily network-based, meaning attackers could exploit this vulnerability remotely. The attack complexity is low, allowing attackers with minimal skills to potentially access these log files if they can interact with the application.
No user interaction is required for exploitation, increasing the severity of this vulnerability. The confidentiality impact is high, as sensitive information could be compromised, while integrity and availability impacts remain unaffected.
Risk & Impact Analysis
Organizations utilizing IBM Cloud Pak for Automation should be aware of the risks associated with CVE-2021-20359. The potential for unauthorized access to sensitive data stored in log files poses a significant risk to data security and regulatory compliance.
Given the medium severity of this vulnerability, it is essential for organizations to address it in their priority patch cycle. The blast radius could extend to all instances of the affected versions, emphasizing the need for a swift and comprehensive remediation strategy.
The CVSS score of 6.5 reflects a moderate urgency, and organizations should evaluate their exposure and take action accordingly. Regular vulnerability assessments and adherence to security best practices will help mitigate risks associated with such vulnerabilities.
