CVE-2022-38122 is a vulnerability identified in POWERCOM CO., LTD.'s UPSMON PRO software, specifically version 2.57. The core issue is the transmission of sensitive information in cleartext over the HTTP protocol, which is inherently insecure. This vulnerability falls under CWE-319, which pertains to the cleartext transmission of sensitive data. Because the data is not encrypted during transmission, an unauthenticated remote attacker can intercept network traffic and gain access to sensitive information without needing any credentials or user interaction. The vulnerability has a CVSS v3.1 base score of 7.5, indicating a high severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) reveals that the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L), requires no privileges (PR:N), and no user interaction (UI:N). The impact is primarily on confidentiality (C:H), with no impact on integrity (I:N) or availability (A:N). No patches or mitigations are currently linked, and there are no known exploits in the wild at the time of publication. The vulnerability affects only version 2.57 of UPSMON PRO, which is a monitoring software for UPS (Uninterruptible Power Supply) systems, typically used in enterprise environments to monitor power infrastructure. The lack of encryption in communication can expose sensitive operational data, potentially including configuration details, status information, or credentials, which could be leveraged for further attacks or espionage. Given the nature of UPSMON PRO, this vulnerability could be exploited to gather intelligence on critical power infrastructure management systems, which are essential for business continuity and operational stability.

For European organizations, the exploitation of this vulnerability could lead to significant confidentiality breaches, especially in sectors relying heavily on uninterrupted power supply monitoring, such as data centers, manufacturing, healthcare, and critical infrastructure. Exposure of sensitive operational data could facilitate further targeted attacks, including lateral movement within networks or preparation for sabotage. Although the vulnerability does not directly affect integrity or availability, the leakage of sensitive information could undermine trust in power management systems and potentially lead to indirect disruptions. Organizations with distributed power management setups or those using UPSMON PRO in multi-site environments are at higher risk due to the increased attack surface. Additionally, regulatory frameworks in Europe, such as GDPR, impose strict requirements on protecting sensitive data, and exploitation of this vulnerability could lead to compliance violations and associated penalties. The absence of authentication and user interaction requirements makes this vulnerability particularly dangerous, as attackers can exploit it remotely without alerting users or administrators.

1. Immediate Network Controls: Implement network segmentation and isolate UPSMON PRO management traffic within secure VLANs or dedicated management networks to reduce exposure to untrusted networks. 2. Use of VPNs or Encrypted Tunnels: Where possible, encapsulate UPSMON PRO HTTP traffic within VPN tunnels or use TLS proxies to enforce encryption despite the software's lack of native HTTPS support. 3. Monitor Network Traffic: Deploy intrusion detection/prevention systems (IDS/IPS) to monitor for unusual HTTP traffic patterns associated with UPSMON PRO communications. 4. Vendor Engagement: Engage with POWERCOM CO., LTD. to request patches or updates that enable encrypted communication protocols (e.g., HTTPS). 5. Access Control: Restrict network access to UPSMON PRO interfaces strictly to authorized personnel and systems using firewall rules and access control lists (ACLs). 6. Alternative Solutions: Evaluate alternative UPS monitoring solutions that support secure communication protocols if immediate patching is not feasible. 7. Incident Response Preparedness: Prepare incident response plans to quickly address any detected exploitation attempts, including forensic analysis of network traffic and logs. 8. Regular Audits: Conduct regular security audits and vulnerability assessments focusing on power management systems and their communication channels.
