CVE-2019-2707 in PeopleSoft Enterprise ELM Enterprise Learning Management
Summary
by MITRE
Vulnerability in the PeopleSoft Enterprise ELM Enterprise Learning Management component of Oracle PeopleSoft Products (subcomponent: Application Search). The supported version that is affected is 9.2. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise PeopleSoft Enterprise ELM Enterprise Learning Management. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in PeopleSoft Enterprise ELM Enterprise Learning Management, 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 ELM Enterprise Learning Management accessible data as well as unauthorized read access to a subset of PeopleSoft Enterprise ELM Enterprise Learning Management 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-2019-2707 resides within the PeopleSoft Enterprise ELM Enterprise Learning Management component, specifically within the Application Search subcomponent of Oracle PeopleSoft Products. This issue affects version 9.2 and represents a critical security weakness that enables unauthenticated attackers to compromise the system through network-based HTTP access. The vulnerability's classification as easily exploitable indicates that attackers require minimal technical expertise to leverage this flaw, making it particularly dangerous in production environments where such systems are often accessible from external networks. The CVSS 3.0 base score of 6.1 reflects the moderate severity of the threat, with confidentiality and integrity impacts rated as low, while the scope of the vulnerability extends beyond the targeted component to potentially affect additional Oracle products within the enterprise ecosystem.
The technical flaw manifests through a lack of proper authentication mechanisms within the Application Search functionality, allowing unauthorized users to execute malicious HTTP requests against the vulnerable system. This weakness creates pathways for attackers to perform unauthorized operations including update, insert, and delete actions on sensitive data within the PeopleSoft Enterprise ELM Enterprise Learning Management system. The vulnerability's requirement for human interaction from individuals other than the attacker suggests that social engineering or targeted phishing campaigns may be necessary to initially gain access, though once the initial foothold is established, the attacker can leverage the vulnerability to manipulate system data. This characteristic aligns with ATT&CK technique T1078.004 which covers legitimate credentials, and CWE-287 which addresses improper authentication mechanisms.
The operational impact of this vulnerability extends beyond immediate data compromise to potentially disrupt business operations and undermine organizational security posture. Successful exploitation can result in unauthorized read access to sensitive educational data, training records, and user information stored within the learning management system. The ability to perform unauthorized updates, inserts, and deletes creates significant risks for data integrity, potentially allowing attackers to modify training content, alter user permissions, or manipulate learning progress tracking. Organizations utilizing PeopleSoft Enterprise ELM Enterprise Learning Management may experience cascading effects across their enterprise applications, as the vulnerability's scope is indicated to potentially impact additional Oracle products, creating broader system compromise risks. The CVSS vector analysis reveals that while the attack requires low complexity and no prior privileges, it does necessitate user interaction, suggesting that the vulnerability could be exploited through targeted campaigns that require some level of social engineering to initially gain access.
Mitigation strategies for CVE-2019-2707 should prioritize immediate patching of affected systems with Oracle's security updates, as this represents the most effective defense against the vulnerability. Organizations should implement network segmentation to limit direct external access to PeopleSoft applications, particularly those with known vulnerabilities. Additional protective measures include deploying web application firewalls to monitor and filter HTTP requests, implementing robust access controls and authentication mechanisms, and establishing comprehensive monitoring protocols to detect unauthorized access attempts. Security teams should conduct thorough vulnerability assessments to identify similar weaknesses across other Oracle products within their environment, as the vulnerability's potential to affect additional systems highlights the need for comprehensive security posture evaluation. Regular security awareness training for personnel can help prevent initial compromise through social engineering attacks that may be necessary to exploit this vulnerability, while maintaining up-to-date security configurations and conducting regular penetration testing can help identify and remediate similar authentication weaknesses in other enterprise applications.
