CVE-2021-35580 in Applications Manager
Summary
by MITRE • 10/20/2021
Vulnerability in the Oracle Applications Manager product of Oracle E-Business Suite (component: View Reports). Supported versions that are affected are 12.1.3 and 12.2.3-12.2.10. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Applications Manager. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Applications Manager, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Applications Manager accessible data as well as unauthorized read access to a subset of Oracle Applications Manager accessible data. CVSS 3.1 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

The vulnerability identified as CVE-2021-35580 resides within Oracle Applications Manager, a component of the Oracle E-Business Suite ecosystem, specifically affecting the View Reports functionality. This security flaw manifests in versions 12.1.3 and 12.2.3 through 12.2.10, representing a significant risk to organizations utilizing these legacy systems. The vulnerability operates through HTTP network access and requires minimal technical prerequisites for exploitation, making it particularly dangerous as it can be leveraged by unauthenticated attackers without requiring any prior access credentials or system privileges.
The technical nature of this vulnerability stems from inadequate input validation and access control mechanisms within the Oracle Applications Manager component. When users interact with the View Reports functionality, the system fails to properly validate user inputs, creating an avenue for malicious actors to manipulate the application's behavior. This weakness allows attackers to perform unauthorized operations including data modification, deletion, and unauthorized data reading within the scope of the affected system. The vulnerability's classification as easily exploitable indicates that the attack vector is straightforward and does not require specialized tools or extensive technical knowledge beyond basic network connectivity.
From an operational perspective, this vulnerability presents a substantial risk to enterprise security posture as it can lead to data integrity compromise and unauthorized access to sensitive business information. The CVSS 3.1 score of 6.1 reflects the moderate severity of the threat, with particular emphasis on confidentiality and integrity impacts. The vulnerability's potential to affect additional products within the Oracle E-Business Suite ecosystem means that exploitation could extend beyond the immediate target, potentially compromising related systems and applications that share common infrastructure or data repositories. The requirement for human interaction from a non-attacker user suggests that social engineering or targeted phishing campaigns could be employed to facilitate successful exploitation, making the threat more sophisticated than simple automated attacks.
The security implications of this vulnerability align with CWE-20, which addresses "Improper Input Validation," and demonstrate characteristics consistent with ATT&CK technique T1213.002 for data from information repositories, indicating that attackers could leverage this flaw to access sensitive data repositories. Organizations should implement immediate mitigations including network segmentation to limit access to the affected Oracle Applications Manager components, deployment of web application firewalls to monitor and filter HTTP traffic, and application-level access controls to restrict unauthorized operations. Additionally, administrators should consider disabling unnecessary HTTP endpoints and implementing comprehensive monitoring solutions to detect anomalous access patterns that could indicate exploitation attempts. The vulnerability underscores the critical importance of maintaining up-to-date security patches and conducting regular vulnerability assessments of legacy systems to prevent similar exposure scenarios in the future.
