        Gadu-Gadu是一款聊天客户端。
        Gadu-Gadu不正确处理文件扩展名,远程攻击者可以利用这个漏洞伪造扩展名,发送恶意文件给Gadu-Gadu客户端接收。
        Bartosz Kwitkowski报告远程验证用户可以建立包含特殊文件名的链接,当Gadu-Gadu接收处理时会以伪造的文件扩展名显示文件并下载,这可通过在文件实际扩展名后追加大量空格字符完成。

Gadu-Gadu is a Polish instant messaging application for Microsoft Windows operating systems.

It is reported that the Gadu-Gadu instant messenger application contains a weakness allowing attackers to obfuscate file extensions.

This may allow an attacker to send potentially malicious executable files to users who think that they are downloading files that are believed to be harmless. 

file.ext%20(220%20kB)%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20.exe

Gadu-Gadu Client File Extension Spoofing
Remote / Network Access Input Manipulation
Loss of Integrity
Exploit Public

- 漏洞描述

Gadu-Gadu chat client contains a flaw that may allow a malicious user to spoof the file extension. The issue is triggered when a remote authenticated user appends a large number of space characters followed by the actual file extension to the spoofed filename. This will cause the recipient's Gadu-Gadu client to display a filename with a spoofed file extension when the recipient attempts to download the file. This flaw leads to a loss of integrity.
