CVE-2023-22105 in BI Publisher
Summary
by MITRE • 10/25/2023
Vulnerability in the BI Publisher product of Oracle Analytics (component: Web Server). Supported versions that are affected are 6.4.0.0.0 and 7.0.0.0.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise BI Publisher. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in BI Publisher, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of BI Publisher accessible data as well as unauthorized read access to a subset of BI Publisher accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N).

The vulnerability identified as CVE-2023-22105 affects Oracle BI Publisher within the Oracle Analytics suite, specifically targeting the Web Server component. This security flaw exists in two major version lines including 6.4.0.0.0 and 7.0.0.0.0, representing a significant exposure for organizations utilizing these platforms. The vulnerability classification as easily exploitable indicates that attackers can leverage this weakness with minimal technical sophistication, making it particularly concerning for enterprise environments where operational continuity is paramount. The CVSS 3.1 score of 5.4 reflects a medium severity level with specific impacts to both confidentiality and integrity, though no direct availability impact is reported.
The technical nature of this vulnerability stems from insufficient access controls within the BI Publisher web server interface. Attackers with low privilege network access via HTTP can exploit this weakness to gain unauthorized access to the system. The requirement for human interaction suggests that while the initial exploitation may be automated, some form of user involvement is necessary for complete compromise, potentially indicating a social engineering component or requiring specific user actions after initial access is gained. This human interaction factor complicates the attack surface but does not eliminate the underlying security flaw. The scope change aspect of this vulnerability means that successful exploitation can potentially impact additional products beyond the immediate BI Publisher system, creating cascading security implications across the broader Oracle Analytics environment.
The operational impact of CVE-2023-22105 extends beyond simple data access violations to encompass significant integrity and confidentiality risks. Attackers can potentially modify, insert, or delete data within the BI Publisher system, which could lead to data corruption, unauthorized information manipulation, or complete data loss. Additionally, unauthorized read access to subsets of data means that sensitive business intelligence information could be accessed without proper authorization. This vulnerability affects the core functionality of BI Publisher, which typically handles critical business reporting and analytics data. The compromise of such systems can lead to business disruption, regulatory compliance issues, and potential financial losses. Organizations relying on BI Publisher for decision-making processes face particular risk as data integrity becomes compromised, potentially leading to incorrect business decisions based on manipulated information.
Organizations should implement immediate mitigations including network segmentation to limit access to BI Publisher systems, implementing robust authentication controls, and ensuring proper firewall rules are in place to restrict HTTP access. The principle of least privilege should be strictly enforced, limiting access to BI Publisher functionality to only authorized personnel. Regular security assessments and monitoring of system access logs are essential to detect potential exploitation attempts. Patch management processes should be prioritized to deploy Oracle's security updates as soon as they become available. Additionally, organizations should consider implementing web application firewalls to provide additional protection layers against exploitation attempts. The vulnerability's classification under CWE 284 (Improper Access Control) and its alignment with ATT&CK technique T1078 (Valid Accounts) demonstrates the fundamental nature of access control failures that enable this type of compromise. Security teams should also establish incident response procedures specifically addressing potential exploitation of this vulnerability to ensure rapid response and containment if compromise occurs.
