Summary

HyperTerminal application for Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003 does not properly validate the length of a value that is saved in a session file, which allows remote attackers to execute arbitrary code via a malicious HyperTerminal session file (.ht), web site, or Telnet URL contained in an e-mail message, triggering a buffer overflow.

Exploit prediction

35.31% chance of exploitation in the next 30 days, higher than 98% of all scored CVEs (FIRST EPSS, 2026-11-08).

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
