---------------
Systems affected: Lycos authenticating servers ,Login forms, Lycos News Site
Risk: 7
Type of errors: Input Validation Flaw
---------------
I encountered  security holes in the Lycos Authentication servers . These
servers are affected by multiple Cross Site Scripting
attacks .The hole is in the form that the login cgi program makes the final
lofin form , injecting a final tag like "> in the m_CBURL
variable you can inject html and script in the login form. In addition i
encountered security holes in the Lycos News server related to XSS attacks.
