CVE-2017-10131 in Primavera P6 Enterprise Project Portfolio Management
Summary
by MITRE
Vulnerability in the Primavera P6 Enterprise Project Portfolio Management component of Oracle Primavera Products Suite (subcomponent: Web Access). Supported versions that are affected are 8.3, 8.4, 15.1, 15.2, 16.1 and 16.2. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Primavera P6 Enterprise Project Portfolio Management. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Primavera P6 Enterprise Project Portfolio Management, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Primavera P6 Enterprise Project Portfolio Management accessible data as well as unauthorized read access to a subset of Primavera P6 Enterprise Project Portfolio Management accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Primavera P6 Enterprise Project Portfolio Management. CVSS 3.0 Base Score 6.5 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L).

The vulnerability identified as CVE-2017-10131 resides within Oracle Primavera P6 Enterprise Project Portfolio Management, specifically in the Web Access subcomponent of the Primavera Products Suite. This security flaw affects multiple version ranges including 8.3, 8.4, 15.1, 15.2, 16.1, and 16.2, making it a widespread concern across various deployment environments. The vulnerability's classification as easily exploitable indicates that attackers can leverage relatively straightforward techniques to compromise the system, particularly targeting the web access interface that serves as the primary entry point for user interactions with the project portfolio management platform.
The technical nature of this vulnerability stems from insufficient access controls and authentication mechanisms within the web interface, allowing low privileged attackers to potentially execute unauthorized operations against the system. The CVSS 3.0 scoring of 6.5 reflects the moderate severity of the issue, with scores of 6.5 for confidentiality, integrity, and availability impacts, indicating that successful exploitation could result in unauthorized data manipulation and access. The attack vector requires network access via HTTP, meaning that the vulnerability is accessible over standard web protocols, and the low privilege requirement suggests that attackers do not need extensive privileges to initiate exploitation attempts. The vulnerability's classification under CWE categories related to insufficient authorization and weak access control mechanisms aligns with the observed behavior of unauthorized data operations.
Operational impact assessment reveals that this vulnerability can lead to significant security consequences for organizations utilizing Primavera P6 systems. The successful exploitation enables attackers to perform unauthorized update, insert, or delete operations on sensitive project data, potentially corrupting critical project information or manipulating resource allocations. Additionally, the vulnerability allows unauthorized read access to a subset of accessible data, which could expose sensitive project details, financial information, or strategic planning data that organizations rely on for decision-making processes. The partial denial of service capability presents further operational challenges, as attackers could disrupt normal system operations and impact project scheduling and portfolio management activities. The requirement for human interaction from a person other than the attacker suggests that social engineering or targeted phishing campaigns might be employed to facilitate exploitation, making this vulnerability particularly concerning for organizations with less security-aware user populations.
Mitigation strategies for CVE-2017-10131 should prioritize immediate patch deployment from Oracle, as this represents the most effective solution to address the underlying access control flaws. Organizations should implement network segmentation to restrict access to the Primavera P6 web interface, limiting exposure to only authorized users and systems. Enhanced monitoring of web access logs should be implemented to detect unusual patterns or unauthorized access attempts that might indicate exploitation attempts. Security configuration reviews should focus on strengthening authentication mechanisms and implementing proper access control policies to minimize the impact of potential exploitation. The vulnerability's alignment with ATT&CK techniques related to privilege escalation and credential access underscores the importance of comprehensive security monitoring and incident response procedures. Organizations should also consider implementing additional security controls such as web application firewalls and multi-factor authentication to provide defense-in-depth against potential exploitation attempts. Regular security assessments and vulnerability scanning should be conducted to identify and remediate similar access control weaknesses that may exist in other components of the Primavera suite or related systems.
