CVE-2024-21117 in Outside In Technology
Summary
by MITRE • 04/17/2024
Vulnerability in the Oracle Outside In Technology product of Oracle Fusion Middleware (component: Outside In Core). Supported versions that are affected are 8.5.6 and 8.5.7. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Outside In Technology executes to compromise Oracle Outside In Technology. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Outside In Technology accessible data as well as unauthorized read access to a subset of Oracle Outside In Technology accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Outside In Technology. CVSS 3.1 Base Score 5.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L).

Analysis

The vulnerability identified as CVE-2024-21117 resides within Oracle Outside In Technology, a component of Oracle Fusion Middleware that handles document processing and conversion tasks. This technology is widely deployed in enterprise environments for handling various document formats and is often integrated into broader middleware solutions where it processes sensitive data. The affected versions 8.5.6 and 8.5.7 represent specific releases where a critical security flaw has been identified, making them susceptible to exploitation by adversaries with minimal privileges.
This vulnerability operates through a privilege escalation mechanism that allows a low-privileged attacker who has already gained access to the system infrastructure where Oracle Outside In Technology operates to compromise the application itself. The flaw stems from inadequate access controls and authorization checks within the Outside In Core component, which processes documents and handles data operations. The vulnerability's exploitability is classified as easily accessible, meaning that an attacker with basic system login credentials can leverage this weakness without requiring specialized tools or extensive technical knowledge.
The security impact of this vulnerability spans across all three core principles of information security. Attackers can achieve unauthorized update, insert, or delete operations against data that the application can access, which represents a significant integrity compromise. Additionally, the flaw enables unauthorized read access to specific subsets of data within the application's accessible scope, creating a confidentiality breach. The availability aspect is also compromised through partial denial of service conditions that can disrupt normal application operations. The CVSS 3.1 score of 5.3 indicates a medium severity vulnerability that requires immediate attention from security administrators.
From a technical perspective, this vulnerability aligns with CWE-284 (Improper Access Control) and represents a classic case of insufficient authorization checks in a document processing system. The attack vector requires local access (AV:L) with low complexity (AC:L) and low privilege requirements (PR:L), making it particularly dangerous in environments where system users might have legitimate access but could be compromised or malicious. The vulnerability's impact extends beyond simple data manipulation to include service disruption, which can significantly affect business operations. The CVSS vector (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L) reflects the comprehensive nature of the threat, showing that the vulnerability can affect confidentiality, integrity, and availability simultaneously.
Organizations should implement immediate mitigations including applying the latest security patches from Oracle, reviewing access controls for systems running Oracle Outside In Technology, and implementing network segmentation to limit potential attack surfaces. The vulnerability's classification under the ATT&CK framework would likely map to privilege escalation techniques and credential access methods, emphasizing the need for comprehensive monitoring and access control policies. Security teams should also conduct thorough vulnerability assessments of their Oracle Fusion Middleware deployments to identify any additional instances of this or similar vulnerabilities that might exist in their infrastructure.
