CVE-2022-21402 in Communications Operations Monitor
Summary
by MITRE • 01/19/2022
Vulnerability in the Oracle Communications Operations Monitor product of Oracle Communications (component: Mediation Engine). Supported versions that are affected are 3.4, 4.2, 4.3, 4.4 and 5.0. Easily exploitable vulnerability allows high privileged attacker with network access via HTTP to compromise Oracle Communications Operations Monitor. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Communications Operations Monitor, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Communications Operations Monitor accessible data as well as unauthorized read access to a subset of Oracle Communications Operations Monitor accessible data. CVSS 3.1 Base Score 4.8 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N).

The vulnerability identified as CVE-2022-21402 affects the Oracle Communications Operations Monitor product within the Mediation Engine component, representing a significant security weakness that impacts multiple supported versions including 3.4, 4.2, 4.3, 4.4, and 5.0. This vulnerability falls under the Common Weakness Enumeration category CWE-284 which specifically addresses improper access control mechanisms, making it a critical concern for organizations relying on this communications infrastructure. The flaw operates at the application layer and requires an attacker with high privileges to execute successful exploitation, though the attack vector through HTTP network access creates substantial risk for organizations with exposed systems.
The technical nature of this vulnerability stems from inadequate access control measures within the Mediation Engine component, which allows authenticated attackers with elevated privileges to perform unauthorized operations against the Oracle Communications Operations Monitor system. The CVSS 3.1 scoring system rates this vulnerability at 4.8 with a base score that reflects both confidentiality and integrity impacts, indicating that successful exploitation could enable attackers to modify or delete sensitive data within the monitored environment. The attack requires human interaction from individuals other than the attacker, suggesting that social engineering or insider threat vectors may be leveraged to achieve successful compromise, which aligns with the ATT&CK framework's concept of privilege escalation through social engineering techniques.
From an operational standpoint, this vulnerability presents substantial risk to organizations managing telecommunications infrastructure through Oracle Communications Operations Monitor, as it can result in unauthorized update, insert, or delete operations against sensitive data accessible through the system. The impact extends beyond the immediate component to potentially affect additional products within the Oracle Communications ecosystem, creating cascading security implications that organizations must consider when assessing their overall security posture. The unauthorized read access capability further compounds the threat by potentially exposing sensitive operational data that could be used for additional attacks or to gain deeper insights into the organization's communications infrastructure.
Organizations should implement immediate mitigations including restricting network access to the affected systems, implementing additional authentication controls, and monitoring for unusual access patterns or unauthorized modifications. The vulnerability's classification under CVSS vector AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N indicates that while network access is required, the attack complexity is low given the high privilege requirements, making it particularly dangerous when combined with insider threats or compromised credentials. Security teams should also consider implementing network segmentation to limit lateral movement and ensure that only authorized personnel have access to the Mediation Engine component, aligning with defense-in-depth strategies recommended by industry standards and frameworks such as NIST Cybersecurity Framework and ISO 27001.
