CVE-2018-2965 in Primavera Unifier
Summary
by MITRE
Vulnerability in the Primavera Unifier component of Oracle Construction and Engineering Suite (subcomponent: Core). The supported version that is affected is 16.x. 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 vulnerability described in CVE-2018-2965 represents a critical security flaw within Oracle Construction and Engineering Suite's Primavera Unifier component, specifically affecting version 16.x. This vulnerability resides in the Core subcomponent of the Primavera Unifier system, which serves as a central platform for project management and collaboration in construction and engineering environments. The affected system operates within a networked environment where HTTP communication is utilized for user interactions, creating a pathway for potential exploitation that extends beyond the immediate component to impact related products within the broader Oracle ecosystem.
This security weakness manifests as an easily exploitable vulnerability that requires minimal technical prerequisites for successful exploitation. The attack vector operates through unauthenticated network access via HTTP protocols, meaning that malicious actors can potentially compromise the system without requiring valid credentials or prior authorization. The vulnerability's classification as easily exploitable indicates that the attack mechanics are straightforward and do not require sophisticated techniques or extensive reconnaissance. The fact that the vulnerability exists within Primavera Unifier, a system designed for managing critical project data in construction environments, creates a particularly concerning threat landscape where unauthorized access could disrupt essential business operations.
The operational impact of this vulnerability extends beyond simple data access, as successful exploitation can result in unauthorized modification capabilities within the system. Attackers can potentially insert, update, or delete data within Primavera Unifier's accessible databases, creating risks of data corruption, manipulation, or complete data loss. Additionally, the vulnerability enables unauthorized read access to a subset of data that the system can provide access to, potentially exposing sensitive project information, financial data, or operational details that could be valuable to malicious actors. The CVSS 3.0 base score of 6.1 reflects the moderate severity of the impact, with confidentiality and integrity being the primary affected security properties, while availability remains relatively unaffected according to the CVSS vector.
The requirement for human interaction from individuals other than the attacker indicates that social engineering or user manipulation may be necessary to achieve successful exploitation, though this does not mitigate the overall risk. This aspect suggests that the vulnerability could be leveraged through phishing attacks, misleading users into performing actions that trigger the exploit, or through targeted campaigns designed to manipulate specific personnel within the organization. The security implications extend beyond the immediate Primavera Unifier environment, as the vulnerability can potentially impact additional products within the Oracle Construction and Engineering Suite ecosystem, creating cascading effects that could compromise multiple interconnected systems.
Organizations should implement comprehensive mitigation strategies that include network segmentation to limit access to the affected system, deployment of web application firewalls to monitor and filter HTTP traffic, and regular security updates to address known vulnerabilities. The vulnerability aligns with CWE-284, which addresses improper access control issues, and may correlate with ATT&CK techniques involving initial access through web application exploitation and privilege escalation through data manipulation. Regular security assessments and user awareness training should be implemented to reduce the risk of successful exploitation, particularly focusing on social engineering attack vectors that may be leveraged to achieve unauthorized access to the system.
