Attack-Flow Graph

Executive Summary

This vulnerability exists in PCViewer vt1000 and is a directory traversal flaw. It allows unauthenticated attackers to read arbitrary files on the system by submitting specially crafted GET requests containing relative path sequences.

By using path traversal sequences such as ../../../../../../../../../../../../etc/passwd, attackers can access sensitive system files that are outside the intended directory.

Impact Analysis

This vulnerability can have a significant impact because it allows attackers to read sensitive files on the system without any authentication.

Access to sensitive files like /etc/passwd can lead to information disclosure, which may facilitate further attacks or compromise system security.
