CVE-2023-3722 is a high-severity OS command injection vulnerability found in the Avaya Aura Device Services Web application. This vulnerability allows remote code execution as the Web server user through a malicious uploaded file. The issue affects Avaya Aura Device Services version 8.1.4.0 and earlier. The potential risk to organizations includes unauthorized access and control over affected systems. Organizations should prioritize patching immediately to mitigate this threat.
The vulnerability has a CVSS score of 8.6, indicating high severity. The attack vector is network-based, and the attack complexity is low, meaning it can be exploited without extensive skills. The potential impacts of successful exploitation include high availability impact and low confidentiality and integrity impacts, making this vulnerability particularly concerning for organizations utilizing the affected product.
As of now, there is no confirmed public exploit available, but the existence of a GitHub proof-of-concept (PoC) indicates that researchers have recognized the risk. Organizations are urged to take this vulnerability seriously and implement corrective measures as part of their security posture.
In conclusion, CVE-2023-3722 represents a significant security risk for organizations using Avaya Aura Device Services. Immediate action is required to patch the vulnerability and prevent potential exploitation.
Vulnerability Details
This vulnerability allows OS command injection in the Avaya Aura Device Services Web application. The official description states, 'An OS command injection vulnerability was found in the Avaya Aura Device Services Web application which could allow remote code execution as the Web server user via a malicious uploaded file.' The CVSS score from NVD is 9.8, classified as critical, indicating high risk. The vulnerability affects all versions prior to vendor patch, specifically version 8.1.4.0 and earlier.
Technical Analysis
The root cause of this vulnerability is an inadequate validation of uploaded files, allowing attackers to execute arbitrary commands on the server. The attack vector is network-based, and an attacker does not need any privileges to exploit it. User interaction is not required, which further increases the risk. The confidentiality impact is low, integrity impact is low, and availability impact is high, as successful exploitation can lead to service disruption.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2023-3722 is significant. Organizations that deploy Avaya Aura Device Services are vulnerable to remote code execution, which can lead to unauthorized access, data breaches, and service interruptions. The blast radius potential is extensive, as the vulnerability affects all installations prior to version 8.1.4.0. Evaluating the urgency based on the CVSS score indicates that organizations should address this vulnerability in their priority patch cycle.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected products include Avaya Aura Device Services, specifically all versions prior to vendor patch 8.1.4.0.
Mitigation & Remediation
Organizations should prioritize patching to version 8.1.4.1 or later as soon as possible to remediate this vulnerability. In cases where the patch is not immediately available, organizations should implement workarounds such as restricting file uploads and monitoring logs for unusual activities. Configuration hardening and network controls should also be enforced to mitigate potential exploitation.
Detection Guidance
Organizations should monitor log indicators for any unusual file upload activities. Behavioral anomalies in server responses or unexpected access patterns should be flagged for further investigation. Additionally, network signatures that correlate with potential exploit attempts should be defined and monitored.
AppSecure Threat Intelligence Insight
