Detection & IOCsextracted from sources · hover to see the quote

  • CVE-2015-5628 is triggered by a specially crafted packet sent to the process that executes control over network communications, enabling remote arbitrary code execution via stack-based buffer overflow.
  • The vulnerability is remotely exploitable with no authentication required and low attacker skill, making it accessible to unsophisticated threat actors targeting Yokogawa ICS products.
  • Monitor network traffic to Yokogawa CENTUM, ProSafe-RS, Exaopc, Exaquantum, STARDOM, FAST/TOOLS, and related OPC server processes for anomalous or malformed packets that could trigger the buffer overflow in the network communications handler.
  • ·No known public exploits specifically target CVE-2015-5628 at the time of advisory publication; detection should focus on anomalous packet patterns rather than known exploit signatures.
  • ·The CVSS v2 base score is 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C), indicating network-accessible, unauthenticated, zero-complexity exploitation with full impact — prioritize network segmentation controls for all affected Yokogawa products.
