CVE-2018-3148 in Construction
Summary
by MITRE
Vulnerability in the Primavera Unifier component of Oracle Construction and Engineering Suite (subcomponent: Web Access). Supported versions that are affected are 15.1, 15.2, 16.1, 16.2, 17.1-17.12 and 18.1-18.8. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Primavera Unifier. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Primavera Unifier, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Primavera Unifier accessible data as well as unauthorized read access to a subset of Primavera Unifier accessible data. CVSS 3.0 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

The CVE-2018-3148 vulnerability resides within the Primavera Unifier component of Oracle Construction and Engineering Suite, specifically within the Web Access subcomponent that serves as a critical interface for project management and collaboration in construction engineering environments. This vulnerability affects multiple version ranges including 15.1 through 15.2, 16.1 through 16.2, 17.1 through 17.12, and 18.1 through 18.8, representing a substantial portion of the software's lifecycle. The vulnerability's classification as easily exploitable indicates that attackers can leverage it with minimal technical sophistication, making it particularly dangerous in production environments where such systems often handle sensitive project data and business-critical information.
The technical flaw manifests as a security weakness that allows unauthenticated attackers to compromise the Primavera Unifier system through standard HTTP network connections without requiring valid credentials or privileged access. This vulnerability operates at the network level, meaning attackers can potentially exploit it from remote locations without physical access to the system infrastructure. The attack requires human interaction from individuals other than the attacker, suggesting that social engineering or targeted phishing campaigns might be necessary to initiate the exploitation process, though the actual technical execution remains relatively straightforward for those with basic network security knowledge.
The operational impact of this vulnerability extends beyond the immediate Primavera Unifier environment and can potentially affect additional products within the Oracle Construction and Engineering Suite ecosystem. This cascading effect represents a significant concern for organizations that rely on integrated software solutions, as compromising one component can create pathways for further exploitation across interconnected systems. The vulnerability's CVSS 3.0 base score of 6.1 reflects moderate severity, with particular emphasis on confidentiality and integrity impacts that can result in unauthorized modification of critical project data. Attackers can achieve unauthorized update, insert, or delete operations on sensitive data, while also gaining read access to subsets of the system's accessible information, potentially exposing proprietary project details, financial data, or strategic business information.
The vulnerability's characteristics align with CWE-284 (Improper Access Control) and fall under ATT&CK technique T1212 (Exploitation for Credential Access) when considering the broader attack surface. Organizations should implement network segmentation to limit access to Primavera Unifier systems, deploy web application firewalls to monitor and filter HTTP traffic, and ensure all systems are updated to patched versions. Regular security assessments and penetration testing should be conducted to identify similar vulnerabilities in related Oracle products, while user awareness training should address the social engineering aspects that may facilitate exploitation through human interaction requirements. The vulnerability underscores the importance of maintaining up-to-date security patches and implementing defense-in-depth strategies to protect against similar access control weaknesses in enterprise software environments.
