CVE-2022-21397 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 low 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 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-2022-21397 affects Oracle Communications Operations Monitor version 3.4, 4.2, 4.3, 4.4, and 5.0, specifically within the Mediation Engine component. This represents a significant security weakness that enables low-privileged attackers with network access through HTTP protocols to compromise the system. The vulnerability's classification as easily exploitable indicates that attackers require minimal technical expertise to leverage this flaw effectively. The attack vector requires network connectivity and specifically targets the HTTP interface of the Operations Monitor system, making it accessible to adversaries who can establish network connections to the affected servers. This vulnerability falls under the Common Weakness Enumeration category CWE-284 which addresses improper access control mechanisms, and aligns with ATT&CK technique T1078 for valid accounts and T1046 for network service scanning.
The technical flaw manifests as insufficient authorization controls within the Mediation Engine component, allowing attackers to perform unauthorized operations against the affected system. The vulnerability's CVSS score of 5.4 reflects moderate severity with confidentiality and integrity impacts rated as low, though the potential for unauthorized data manipulation remains significant. Attackers can achieve unauthorized update, insert, or delete operations on specific data accessible through the Operations Monitor system, while also gaining unauthorized read access to subsets of available data. The requirement for human interaction from a person other than the attacker suggests that social engineering or user manipulation may be necessary to complete the attack chain, though this does not mitigate the underlying security weakness. The impact extends beyond the immediate system as attacks may affect additional products connected to or dependent on the Operations Monitor infrastructure.
The operational impact of this vulnerability extends across the entire Oracle Communications ecosystem, particularly affecting network monitoring and operations management functions. Organizations utilizing these specific versions of Oracle Communications Operations Monitor face potential data integrity compromise and unauthorized information disclosure risks. The vulnerability's ability to affect multiple products within the communications infrastructure creates cascading security implications that could disrupt service availability and compromise sensitive operational data. System administrators must consider the potential for unauthorized modifications to operational configurations and monitoring data, which could mask security incidents or create false operational states. The low privilege requirement means that even users with minimal system access could potentially exploit this vulnerability, increasing the attack surface and making detection more challenging.
Mitigation strategies should focus on immediate patch deployment for all affected versions of Oracle Communications Operations Monitor, with particular attention to the Mediation Engine component. Organizations should implement network segmentation to limit access to the Operations Monitor systems and restrict HTTP access to authorized personnel only. Additional security measures include enabling multi-factor authentication for administrative access, implementing network access controls, and establishing monitoring for unusual HTTP traffic patterns. The vulnerability's classification as requiring human interaction suggests that user awareness training should be implemented to prevent social engineering attacks that could exploit this weakness. Security teams should also consider implementing database activity monitoring and access logging to detect unauthorized data manipulation attempts. Regular security assessments and vulnerability scanning should be conducted to identify similar access control weaknesses in other Oracle Communications products and related systems. Organizations should also review their incident response procedures to ensure readiness for potential exploitation of this vulnerability, particularly given its potential to affect multiple interconnected systems within the communications infrastructure.
