CVE-2024-20943 in Knowledge Management
Summary
by MITRE • 02/17/2024
Vulnerability in the Oracle Knowledge Management product of Oracle E-Business Suite (component: Internal Operations). Supported versions that are affected are 12.2.3-12.2.13. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Knowledge Management. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Knowledge Management, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Knowledge Management accessible data as well as unauthorized read access to a subset of Oracle Knowledge Management accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N).

The vulnerability identified as CVE-2024-20943 resides within Oracle Knowledge Management, a component of the Oracle E-Business Suite operating under the Internal Operations framework. This security flaw affects a specific range of versions from 12.2.3 through 12.2.13, representing a significant portion of the Oracle E-Business Suite ecosystem. The vulnerability classification as easily exploitable indicates that threat actors can leverage this weakness with minimal technical sophistication, particularly targeting low-privileged users who can access the system through HTTP network protocols. The attack vector specifically requires network access via HTTP, making it accessible to remote adversaries who can potentially leverage this weakness from external network positions.
The technical nature of this vulnerability stems from insufficient authorization controls within the Oracle Knowledge Management component, allowing attackers with minimal privileges to perform unauthorized operations against the system's data. The CVSS 3.1 base score of 5.4 reflects the moderate severity level, with the vector CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N indicating that the attack requires network access with low complexity, only low privilege levels, and human interaction from users other than the attacker. This scope change aspect of the vulnerability means that while the initial compromise targets Oracle Knowledge Management, the impact extends to additional products within the Oracle E-Business Suite environment, potentially creating cascading security effects throughout the organization's business applications.
The operational impact of this vulnerability manifests through unauthorized data modification and access capabilities that could compromise both the integrity and confidentiality of sensitive information. Attackers can achieve unauthorized update, insert, or delete operations against data accessible through Oracle Knowledge Management, while also gaining unauthorized read access to specific subsets of the system's data. This dual impact on both integrity and confidentiality aligns with CWE-284 (Improper Access Control) and represents a significant concern for organizations relying on Oracle E-Business Suite for critical business operations. The requirement for human interaction suggests that social engineering or user manipulation may be necessary components of the attack, potentially involving phishing or other deceptive techniques to trigger the vulnerability through legitimate user actions.
Organizations should implement immediate mitigation strategies including applying the relevant Oracle critical patch updates, reviewing and strengthening access controls for Oracle Knowledge Management components, and implementing network segmentation to limit exposure. The vulnerability's classification under the ATT&CK framework would likely map to techniques involving privilege escalation and credential access, with the scope change aspect potentially triggering lateral movement within the Oracle E-Business Suite environment. Security monitoring should focus on unusual data access patterns and unauthorized modifications within Oracle Knowledge Management, while user awareness training should address the social engineering components that enable exploitation. The vulnerability's impact on multiple products within the Oracle E-Business Suite ecosystem emphasizes the importance of comprehensive security assessments and coordinated patch management across all affected components to prevent cascading failures that could compromise the entire suite of business applications.
