AlienVault OTX Vulnerabilities

AlienVault OTX Malware

A denial-of-service vulnerability due to improper prioritization of network traffic over protection mechanism exists in Relion 670/650 and SAM600-IO series device that if exploited could potentially cause critical functions like LDCM (Line Distance Communication Module) to malfunction.

CVE-2025-2403 is a high-severity denial-of-service (DoS) vulnerability affecting Hitachi Energy's Relion 670/650 and SAM600-IO series devices, specifically impacting versions 2.2.2.6 through 2.2.6.0. These devices are critical components in electrical grid protection and automation systems. The vulnerability arises from improper allocation of resources without adequate limits or throttling, classified under CWE-770. Specifically, the devices fail to properly prioritize network traffic over their protection mechanisms, which can be exploited by an unauthenticated attacker remotely over the network without requiring user interaction. Exploitation can cause critical functions such as the Line Distance Communication Module (LDCM) to malfunction, potentially disrupting protective relaying and communication essential for grid stability. The CVSS v3.1 score of 7.5 reflects a high severity, with network attack vector, low attack complexity, no privileges or user interaction required, and an impact limited to availability (no confidentiality or integrity impact). No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability’s root cause is the lack of resource allocation limits or throttling, which allows an attacker to overwhelm the device’s processing capabilities, leading to denial of critical protective functions. Given the role of these devices in power grid protection, the vulnerability poses a significant risk to operational continuity and grid reliability if exploited.
