CVE-2017-3500 in Primavera Gateway
Summary
by MITRE
Vulnerability in the Primavera Gateway component of Oracle Primavera Products Suite (subcomponent: Primavera Desktop Integration). Supported versions that are affected are 1.0, 1.1, 14.2, 15.1, 15.2, 16.1 and 16.2. Easily "exploitable" vulnerability allows high privileged attacker with network access via HTTP to compromise Primavera Gateway. While the vulnerability is in Primavera Gateway, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Primavera Gateway accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Primavera Gateway. CVSS 3.0 Base Score 8.7 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:H).

The vulnerability identified as CVE-2017-3500 resides within the Primavera Gateway component of Oracle Primavera Products Suite, specifically affecting the Primavera Desktop Integration subcomponent. This security flaw impacts multiple version ranges including 1.0, 1.1, 14.2, 15.1, 15.2, 16.1, and 16.2, representing a significant attack surface across the Primavera product ecosystem. The vulnerability's classification as easily exploitable indicates that attackers with minimal technical expertise can leverage this weakness, making it particularly dangerous for organizations relying on these project management platforms. The CVSS 3.0 base score of 8.7 reflects the severity of the potential impact, with high confidentiality and availability risks that can compromise critical project data and system availability.
The technical nature of this vulnerability stems from insufficient input validation within the Primavera Gateway component, which processes requests from the Primavera Desktop Integration module. Attackers with high privileged access and network connectivity via HTTP can exploit this weakness to gain unauthorized access to sensitive data stored within the Primavera Gateway environment. This access extends beyond the immediate component to potentially impact other interconnected Primavera products within the suite, creating cascading security risks. The vulnerability's ability to cause complete denial of service through system hangs or frequent crashes represents a severe operational impact that can disrupt critical project management workflows and business operations.
From an operational standpoint, the vulnerability presents a substantial risk to organizations utilizing Primavera products for enterprise project management and scheduling. The confidentiality impact of high severity means that sensitive project data, resource allocations, and business-critical information could be exposed to unauthorized parties. The availability impact of high severity indicates that attackers can potentially bring down the entire Primavera Gateway service, causing complete system downtime that affects multiple users and departments. This vulnerability aligns with CWE-20, which addresses "Improper Input Validation," and represents a classic example of how inadequate security controls in enterprise software can create significant attack vectors. The CVSS vector analysis shows that the attack requires network access with high privileges and no user interaction, making it particularly concerning for environments where network access is not properly restricted.
Organizations should implement immediate mitigations including applying the relevant Oracle security patches, implementing network segmentation to limit access to the Primavera Gateway component, and conducting thorough network monitoring for suspicious HTTP traffic patterns. The ATT&CK framework categorizes this vulnerability under initial access techniques, specifically leveraging network-based attacks to gain unauthorized system access. Additional protective measures include implementing strict access controls, regular security assessments of Primavera installations, and establishing incident response procedures specifically for this type of vulnerability. The interconnected nature of Primavera products means that organizations should also review their overall security posture across all Primavera components to prevent lateral movement of attacks. Given the high severity score and the potential for complete system compromise, organizations should prioritize this vulnerability in their security remediation schedules and consider implementing temporary network restrictions while permanent fixes are deployed.
