CVE-2017-3300 in PeopleSoft
Summary
by MITRE
Vulnerability in the PeopleSoft Enterprise PeopleTools component of Oracle PeopleSoft Products (subcomponent: Multichannel Framework). 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 v3.0 Base Score 6.1 (Confidentiality and Integrity impacts).

The CVE-2017-3300 vulnerability represents a critical security flaw within Oracle PeopleSoft Enterprise PeopleTools, specifically within the Multichannel Framework subcomponent. This vulnerability affects versions 8.54 and 8.55 of the PeopleTools suite, which are widely deployed enterprise applications used for business process management and human capital management. The vulnerability stems from insufficient input validation and authentication mechanisms within the web interface, creating a pathway for unauthorized access to sensitive enterprise data. The flaw is classified as easily exploitable due to its accessibility over HTTP networks without requiring authentication credentials, making it particularly dangerous in enterprise environments where PeopleSoft systems are exposed to external networks.
The technical implementation of this vulnerability involves a weakness in the application's request handling mechanism, where the Multichannel Framework fails to properly validate user input and authenticate requests before processing them. This creates an opportunity for attackers to manipulate HTTP requests and gain access to restricted functionality within the PeopleTools environment. The vulnerability operates at the application layer and leverages the fact that the system does not adequately enforce access controls for specific data operations. Attackers can potentially exploit this weakness to perform unauthorized data manipulation operations including updates, inserts, and deletes on sensitive information within the PeopleSoft database. The impact extends beyond the immediate PeopleTools component as the vulnerability can affect interconnected systems and applications that rely on PeopleSoft for data exchange and business process automation.
The operational impact of CVE-2017-3300 is significant for organizations utilizing Oracle PeopleSoft systems, as successful exploitation can lead to data integrity compromise and unauthorized access to sensitive business information. The vulnerability's CVSS v3.0 base score of 6.1 indicates a moderate to high risk level, with particular emphasis on confidentiality and integrity impacts. Attackers can potentially access subsets of data that may include employee records, financial information, or other sensitive business data depending on the organization's PeopleSoft implementation. The requirement for human interaction from individuals other than the attacker suggests that social engineering or targeted phishing attacks might be necessary to initially gain access, though once the vulnerability is exploited, the attacker can operate with minimal additional privileges. This vulnerability aligns with CWE-287 which addresses improper authentication issues, and can be mapped to ATT&CK technique T1078 for valid accounts and T1046 for network service scanning.
Organizations should implement immediate mitigations including network segmentation to limit access to PeopleSoft systems, implementing robust web application firewalls, and ensuring that the affected PeopleTools versions are updated with Oracle's security patches. The vulnerability demonstrates the importance of maintaining up-to-date enterprise applications and implementing defense-in-depth strategies. Additional security measures should include monitoring for suspicious HTTP requests, implementing stronger authentication mechanisms, and conducting regular vulnerability assessments of enterprise applications. Organizations should also consider implementing database activity monitoring to detect unauthorized data access patterns and establish incident response procedures specifically for PeopleSoft-related security incidents. The vulnerability underscores the necessity of following security best practices such as the principle of least privilege and regular security testing to prevent similar exploits from compromising enterprise data integrity and confidentiality.
