xArrow Multiple Vulnerabilities

Low RiskICS-CERT ICSA-12-145-02Feb 25, 2012
Summary

xArrow software versions prior to 3.4.1 contain multiple buffer overflow and null pointer dereference vulnerabilities (CWE-119, CWE-122, CWE-125, CWE-476). These memory safety issues could allow an attacker to cause denial of service or potentially execute arbitrary code.

What this means
What could happen
An attacker could crash xArrow or potentially run arbitrary commands, disrupting the software's functionality and potentially affecting any automated processes or reporting that depend on it.
Who's at risk
Organizations using xArrow for data collection, reporting, or automation in water and electrical utilities should assess this risk. xArrow is often deployed as a data aggregation or historical logging tool that feeds information to other systems.
How it could be exploited
An attacker would need to send specially crafted input or data to xArrow that triggers one of the buffer overflow or null pointer dereference conditions. The specific attack vector depends on how xArrow accepts input (network connections, file processing, or local data handling).
Prerequisites
  • xArrow version prior to 3.4.1 must be deployed
  • Attacker must be able to reach the xArrow instance or provide malformed input that the software processes

xArrow software: <3.4.1 has reached End of Life. The vendor will not release a patch. Apply the following compensating controls:
HARDENINGMonitor xArrow logs for unexpected crashes or errors that could indicate exploitation attempts
HARDENINGVerify input validation and error handling in any custom integrations or scripts that feed data to xArrow
