CVE-2023-22109: Vulnerability in Oracle Business Intelligence Enterprise Edition Opens Door to Unauthorized Data Access

A new vulnerability has been found in the Oracle Business Intelligence Enterprise Edition (OBIEE) product of Oracle Analytics. This vulnerability affects the Analytics Web Dashboards component in versions 6.4..., 7...., and 12.2.1.4..

This weakness allows low privileged attackers with network access via HTTP to compromise OBIEE, potentially leading to unauthorized access to sensitive data. While successful attacks do require human interaction from someone other than the attacker, this flaw could still lead to unauthorized updating, inserting, or deleting of some accessible OBIEE data, as well as unauthorized read access to a subset of accessible OBIEE data.

The vulnerability has been assigned a CVSS 3.1 Base Score of 4.6, with Confidentiality and Integrity impacts. The CVSS Vector is (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:N).

Exploit Details

The vulnerability lies in the Analytics Web Dashboards component of OBIEE, which handles user interaction and data visualization. This weakness can be exploited by an attacker by sending crafted HTTP requests to the vulnerable system, potentially leading to unauthorized data manipulation or access.

To better understand the risks associated with this vulnerability, let's examine a simplified example of the code snippet that could potentially be affected:

// Vulnerable code snippet in OBIEE

function processData(userInput) {
  // Parse the user input and perform operations
  // ...
  data = backend.getData(userInput);
  result = processData(data);
  // Update the dashboard with the obtained data
  // ...
}

// Attacker sends crafted HTTP request
httpRequest.send("vulnerable_url", { craftedData: "crafted_data" });

In this example, the attacker could craft an HTTP request containing malicious data that could manipulate the target OBIEE system. Although human interaction is required on the target system to trigger the vulnerability, this example demonstrates how an attacker might exploit it to gain unauthorized access to sensitive data or perform unauthorized actions.

Mitigation

Oracle has released patches to address this vulnerability, and users are strongly encouraged to apply the latest updates as soon as possible. Organizations should prioritize patching systems that are directly accessible from the internet or are hosting sensitive data.

In addition to applying patches, organizations should also implement strong access controls, network segmentation, and regular monitoring to minimize the risk of exploitation.

Conclusion

CVE-2023-22109 is a concerning vulnerability in Oracle Business Intelligence Enterprise Edition that could lead to unauthorized data access and manipulation by attackers. Users and organizations should urgently apply patches provided by Oracle and take additional security measures to minimize the risk of falling victim to successful attacks exploiting this vulnerability.
