AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability exists in PuTTY versions 0.77 before 0.84. PuTTY uses a copy of its icon as a trust indication for TELNET data. However, the trust status represented by this icon is not cleared between proxy authentication and the main session, which can lead to incorrect trust assumptions.


How can this vulnerability impact me? :

Because the trust status is not properly cleared between proxy authentication and the main session, users or systems might mistakenly trust TELNET data that should not be trusted. This could potentially lead to security issues such as accepting malicious data or unauthorized access during the session.
