CVE-2019-2608 in Outside In Technology
Summary
by MITRE
Vulnerability in the Oracle Outside In Technology component of Oracle Fusion Middleware (subcomponent: Outside In Filters). Supported versions that are affected are 8.5.3 and 8.5.4. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP 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. Note: Outside In Technology is a suite of software development kits (SDKs). The protocol and CVSS score depend on the software that uses the Outside In Technology code. The CVSS score assumes that the software passes data received over a network directly to Outside In Technology code, but if data is not received over a network the CVSS score may be lower. CVSS 3.0 Base Score 7.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L).

The vulnerability identified as CVE-2019-2608 affects Oracle Outside In Technology, a critical component within Oracle Fusion Middleware that serves as a suite of software development kits enabling applications to process various document formats. This vulnerability specifically resides within the Outside In Filters subcomponent and impacts versions 8.5.3 and 8.5.4 of the Oracle Fusion Middleware suite. The flaw represents a significant security weakness that can be exploited by unauthenticated attackers who gain network access through HTTP protocols, making it particularly dangerous in enterprise environments where such middleware components are extensively deployed.
The technical nature of this vulnerability stems from inadequate input validation and processing within the Outside In Technology filters, which allows maliciously crafted data to be processed through the vulnerable code paths. This weakness enables attackers to manipulate the processing flow and potentially execute unauthorized operations against the affected system. The vulnerability's classification as easily exploitable indicates that the attack vectors are straightforward and do not require specialized knowledge or privileged access to initiate successful exploitation attempts. The CVSS score of 7.3 reflects the severity across confidentiality, integrity, and availability impacts, with the vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L indicating network-based attacks with low complexity and no prerequisites for exploitation.
The operational impact of this vulnerability extends across multiple security domains, providing attackers with unauthorized capabilities to modify, insert, or delete data within the scope of accessible Oracle Outside In Technology resources. Additionally, the vulnerability enables unauthorized read access to sensitive data subsets, potentially exposing confidential information processed through the affected middleware. The partial denial of service aspect means that attackers can disrupt service availability to some degree, affecting system reliability and operational continuity. This vulnerability particularly concerns organizations using Oracle Fusion Middleware in critical business processes, as it could compromise document processing workflows and data integrity across multiple applications.
Organizations should implement immediate mitigations including applying the relevant Oracle patches and updates to address the vulnerability in affected versions. Network segmentation and access controls should be strengthened to limit exposure of the vulnerable components to untrusted networks. Monitoring and logging mechanisms should be enhanced to detect potential exploitation attempts through HTTP traffic patterns. The vulnerability aligns with CWE-20 (Improper Input Validation) and may map to ATT&CK techniques involving command and control communications, data manipulation, and privilege escalation through network-based attacks. Security teams should also consider implementing network-based intrusion detection systems to monitor for exploitation attempts and maintain updated threat intelligence regarding similar vulnerabilities in Oracle middleware components.
