SpecView Directory Traversal
Low RiskICS-CERT ICSA-13-011-02Oct 15, 2013
Summary
SpecView versions 2.5_Build_853 and earlier contain a directory traversal vulnerability (CWE-23) that allows an attacker to read or write arbitrary files on the system. The application does not properly validate file path inputs, enabling attackers to bypass directory restrictions and access sensitive files outside the intended scope of the application.
What this means
What could happen
An attacker with network access to SpecView could read or write arbitrary files on the affected system through directory traversal, potentially compromising configuration files, process data, or enabling further system compromise.
Who's at risk
Water utilities, electric utilities, and other critical infrastructure operators using SpecView for SCADA data visualization or process monitoring. Any environment where SpecView is used to display or manage operational data from PLCs, RTUs, or process control systems is affected.
How it could be exploited
An attacker sends a crafted request to SpecView containing path traversal sequences (e.g., ../ or absolute paths) to access files outside the intended directory. The vulnerable application does not properly validate or sanitize the file path, allowing the attacker to read sensitive files or write malicious content to arbitrary locations on the system.
Prerequisites
- Network access to SpecView application port
- SpecView version 2.5_Build_853 or earlier
