CVE-2025-5113: CWE-77 Improper Neutralization of Special Elements used in a Command ('Command Injection') in Diviotec nbr222p
The Diviotec professional series exposes a web interface. One endpoint is vulnerable to arbitrary command injection and hardcoded passwords are used.
AI Analysis
Technical Summary
CVE-2025-5113 is a high-severity vulnerability affecting the Diviotec nbr222p device, part of the Diviotec professional series. This device exposes a web interface that includes an endpoint vulnerable to arbitrary command injection, classified under CWE-77 (Improper Neutralization of Special Elements used in a Command). The vulnerability allows an attacker with low privileges and no user interaction to execute arbitrary system commands remotely by injecting malicious input into the vulnerable endpoint. Additionally, the device uses hardcoded passwords, which further exacerbates the risk by enabling easier unauthorized access or privilege escalation. The CVSS 4.0 score of 8.6 reflects the high impact on confidentiality, integrity, and availability, with attack vector being adjacent network (AV:A), low attack complexity (AC:L), no attack prerequisites (AT:N), and low privileges required (PR:L). The vulnerability does not require user interaction (UI:N) and has high impact on all security properties (VC:H, VI:H, VA:H). No patches are currently available, and no known exploits have been reported in the wild as of the publication date. The combination of command injection and hardcoded credentials makes this vulnerability particularly dangerous, as it can lead to full system compromise, data leakage, or disruption of device functionality.
Potential Impact
For European organizations using Diviotec nbr222p devices, this vulnerability poses significant risks. The arbitrary command injection can allow attackers to execute malicious commands, potentially leading to unauthorized access, data exfiltration, or disruption of critical services. The presence of hardcoded passwords increases the likelihood of successful exploitation and lateral movement within networks. Organizations relying on these devices for security, surveillance, or operational technology may face confidentiality breaches, integrity violations, and availability outages. Given the device's network adjacency attack vector, attackers within the same local or VPN network segment could exploit this vulnerability without needing direct internet exposure. This could impact sectors such as manufacturing, critical infrastructure, and enterprise environments where Diviotec devices are deployed. The lack of patches necessitates immediate mitigation to prevent exploitation, especially in environments with sensitive data or critical operations.
Mitigation Recommendations
1. Immediate network segmentation: Isolate Diviotec nbr222p devices on dedicated VLANs or network segments with strict access controls to limit exposure to trusted users and systems only. 2. Implement strong network-level authentication and monitoring: Use network access control (NAC) solutions to enforce authentication before access and monitor traffic for anomalous command injection patterns. 3. Replace or disable vulnerable endpoints: If possible, disable the vulnerable web interface endpoint or replace the device with a secure alternative until a patch is available. 4. Change default or hardcoded passwords: Although hardcoded passwords are difficult to change, check for any available configuration options or firmware updates that allow password modification; otherwise, treat devices as compromised and isolate them. 5. Employ intrusion detection/prevention systems (IDS/IPS): Deploy IDS/IPS with signatures or heuristics to detect command injection attempts targeting Diviotec devices. 6. Monitor logs and network traffic for suspicious activities related to the device. 7. Engage with Diviotec support or vendor channels to request patches or firmware updates addressing this vulnerability. 8. Develop incident response plans specifically for potential compromise of these devices.
