CVE-2017-10249 in PeopleSoft Enterprise PeopleTools
Summary
by MITRE
Vulnerability in the PeopleSoft Enterprise PeopleTools component of Oracle PeopleSoft Products (subcomponent: Integration Broker). Supported versions that are affected are 8.54 and 8.55. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise PeopleSoft Enterprise PeopleTools. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in PeopleSoft Enterprise PeopleTools, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of PeopleSoft Enterprise PeopleTools accessible data as well as unauthorized read access to a subset of PeopleSoft Enterprise PeopleTools 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 identified as CVE-2017-10249 resides within the PeopleSoft Enterprise PeopleTools component, specifically within the Integration Broker subcomponent of Oracle PeopleSoft Products. This security flaw affects versions 8.54 and 8.55 of the software, representing a significant concern for organizations utilizing these enterprise applications. The vulnerability operates at the network level, requiring only HTTP access for exploitation, which makes it particularly dangerous as it can be leveraged by attackers without requiring any authentication credentials. The CVSS 3.0 scoring system rates this vulnerability with a base score of 6.1, indicating a medium severity threat that specifically impacts both confidentiality and integrity aspects of the affected systems.
The technical nature of this vulnerability stems from insufficient input validation within the Integration Broker functionality, allowing malicious actors to craft specially formatted HTTP requests that can manipulate the underlying PeopleTools application. This flaw enables unauthenticated attackers to perform unauthorized operations including update, insert, and delete actions against specific data sets accessible through the PeopleTools environment. The attack requires human interaction from users other than the attacker, suggesting that the exploitation might occur through social engineering or targeted phishing campaigns that trick legitimate users into performing actions that trigger the vulnerability. The impact extends beyond the immediate PeopleTools component, potentially affecting additional Oracle products within the enterprise ecosystem due to the interconnected nature of PeopleSoft applications.
Organizations compromised by this vulnerability face significant operational risks including data integrity breaches where unauthorized modifications can alter critical business data, as well as confidentiality violations that allow unauthorized access to sensitive information. The potential for unauthorized data access creates substantial business disruption risks, particularly in environments where PeopleSoft serves as a core component of financial, human resources, or enterprise resource planning systems. The vulnerability's classification under CWE-20 (Improper Input Validation) aligns with common attack patterns documented in the MITRE ATT&CK framework, specifically relating to privilege escalation and credential access techniques. The CVSS vector analysis reveals that while the attack requires low complexity and no prior privileges, the successful exploitation can cause considerable damage to data integrity and confidentiality, with the potential for cascading effects across interconnected enterprise applications.
Effective mitigation strategies for CVE-2017-10249 should include immediate implementation of Oracle's security patches and updates, alongside network-level restrictions that limit HTTP access to the affected Integration Broker components. Organizations should deploy web application firewalls to monitor and filter suspicious HTTP requests, while also implementing network segmentation to isolate PeopleSoft environments from general network access. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses within the broader enterprise infrastructure, as this vulnerability demonstrates the importance of validating input across all application components. The remediation process must also include user awareness training to prevent social engineering attacks that could exploit the human interaction requirement, while maintaining comprehensive logging and monitoring capabilities to detect potential exploitation attempts. Additionally, organizations should review their access controls and implement the principle of least privilege to minimize the potential impact of any successful exploitation attempts.
