UltraVNC repeater ships hardcoded default admin password allowing unauthenticated admin access
Vulnerability Description
UltraVNC repeater through 1.8.2.2 initializes the HTTP administration server with a hardcoded default password. In repeater/webgui/settings.c:197, when settings2.txt is absent on first run the repeater writes the literal string "adminadmi2" as the admin password via strcpy_s(saved_password, 64, "adminadmi2"). The HTTP Basic-auth handler wi_decode_auth() checks this password without rate-limiting or lockout. Any remote attacker who can reach the repeater HTTP port (default TCP 80) can authenticate as administrator using the well-known default credential on a fresh or unmodified installation, gaining full control of the repeater configuration including allow/deny rules and session visibility.

UltraVNC 信任管理问题漏洞
Vulnerability Description
uvnc UltraVNC是uvnc个人开发者开源的一款Windows远程控制软件。 UltraVNC 1.8.2.2及之前版本存在信任管理问题漏洞,该漏洞源于HTTP管理服务器使用硬编码默认密码初始化,在首次运行时将字符串“adminadmi2”写入为管理员密码,且HTTP基本认证处理程序无速率限制或锁定机制,可导致远程攻击者使用已知默认凭据以管理员身份进行身份验证,从而完全控制中继器配置(包括允许/拒绝规则和会话可见性)。
