Summary
by MITRE • 10/25/2023
Atos Unify OpenScape 4000 Platform V10 R1 before Hotfix V10 R1.42.2 4000 and Manager Platform V10 R1 before Hotfix V10 R1.42.2 allow command injection by an authenticated attacker into the platform operating system, leading to administrative access, via dtb pages of the platform portal. This is also known as OSFOURK-23719.

The CVE-2023-45356 vulnerability affects the Atos Unify OpenScape 4000 Platform and Manager Platform versions prior to specific hotfixes, representing a critical command injection flaw that enables authenticated attackers to execute arbitrary operating system commands. This vulnerability exists within the platform's portal interface through the dtb pages, which serve as entry points for administrative functions. The flaw allows an attacker who has already gained authentication access to the platform to escalate privileges and gain full administrative control over the underlying operating system. The vulnerability is particularly concerning because it transforms a standard authenticated access point into a potential gateway for complete system compromise, making it a significant concern for organizations relying on these telephony and communication platforms.
The technical implementation of this command injection vulnerability stems from insufficient input validation and sanitization within the dtb pages of the platform portal. When authenticated users interact with these specific pages, the system fails to properly sanitize user-supplied input before incorporating it into system commands or shell executions. This lack of proper input filtering creates an environment where malicious payloads can be injected directly into the command execution chain, allowing attackers to bypass normal access controls and execute arbitrary code with the privileges of the platform's operating system. The vulnerability is classified as a command injection flaw under CWE-77, which specifically addresses situations where user-controllable data is used in system commands without proper validation or escaping mechanisms. This type of vulnerability is particularly dangerous because it can be exploited to gain root or administrative privileges on the target system.
The operational impact of this vulnerability extends far beyond simple privilege escalation, as it provides attackers with complete control over the affected platforms. Once exploited, attackers can manipulate the telephony infrastructure, access sensitive communication data, modify system configurations, and potentially use the compromised platform as a launch point for further attacks within the network. The vulnerability affects both the OpenScape 4000 Platform and Manager Platform, which are commonly deployed in enterprise environments for critical communication services, making the potential impact substantial. Organizations may face service disruptions, data breaches, and compliance violations if these systems are compromised. The vulnerability's presence in the platform portal makes it particularly attractive to attackers because it requires minimal privileges to exploit, and the effects can be devastating to business continuity and security posture. According to ATT&CK framework, this vulnerability maps to T1059.001 (Command and Scripting Interpreter: PowerShell) and T1068 (Exploitation for Privilege Escalation) techniques, demonstrating how the vulnerability can be leveraged for lateral movement and system compromise.
Organizations should immediately implement mitigations including applying the vendor-provided hotfixes V10 R1.42.2 for both the OpenScape 4000 Platform and Manager Platform. Network segmentation and access controls should be enhanced to limit access to the affected portal pages to only authorized administrative personnel. Input validation should be strengthened across all user-facing interfaces to prevent similar injection attacks, and regular security assessments should be conducted to identify potential vulnerabilities in legacy systems. Additionally, monitoring should be implemented to detect unusual command executions or access patterns that might indicate exploitation attempts. The vulnerability highlights the importance of maintaining current security patches and the need for robust input validation in enterprise communication platforms, particularly those that handle sensitive business communications and may be targeted by sophisticated attack campaigns.
