EUVD-2023-31068

Comprehensive Technical Analysis of EUVD-2023-31068

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2023-31068 pertains to Docker-based datastores used by IBM Instana (Observability with Instana) versions 239-0 through 239-2, 241-0 through 241-2, and 243-0. The primary issue is the lack of authentication requirements for accessing these datastores, which allows any attacker within the network to gain read/write access.

Severity Evaluation:

• CVSS Base Score: 9.1
• CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

The high base score of 9.1 indicates a critical vulnerability. The CVSS vector breakdown shows:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Unchanged (U)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): None (N)

This vulnerability poses a significant risk due to the ease of exploitation and the high impact on confidentiality and integrity.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network Access: An attacker with network access to the Docker-based datastores can exploit this vulnerability.
• Internal Threats: Insiders or malicious actors with access to the internal network can easily exploit this vulnerability.

Exploitation Methods:

• Unauthorized Access: Attackers can access the datastores without any authentication, allowing them to read sensitive data and potentially modify it.
• Data Exfiltration: Sensitive information stored in the datastores can be exfiltrated.
• Data Tampering: Attackers can modify the data, leading to integrity issues and potential disruption of services.

3. Affected Systems and Software Versions

Affected Software:

• IBM Observability with Instana versions:
  • 239-0 through 239-2
  • 241-0 through 241-2
  • 243-0

Affected Systems:

• Systems running the specified versions of IBM Observability with Instana using Docker-based datastores.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Network Segmentation: Implement strict network segmentation to limit access to the Docker-based datastores.
• Access Controls: Enforce access controls and authentication mechanisms to restrict unauthorized access.
• Monitoring: Increase monitoring and logging of access to the datastores to detect any unauthorized activities.

Long-Term Mitigation:

• Patching: Apply the latest patches and updates provided by IBM to address this vulnerability.
• Configuration Review: Review and update the configuration of the Docker-based datastores to ensure proper authentication and access controls are in place.
