Summary

Microsoft Windows XP, Server 2003 and 2008, and Vista exposes I/O activity measurements of all processes, which allows local users to obtain sensitive information, as demonstrated by reading the I/O Other Bytes column in Task Manager (aka taskmgr.exe) to estimate the number of characters that a different user entered at a runas.exe password prompt, related to a "benchmarking attack."

Exploit prediction

1.45% chance of exploitation in the next 30 days, higher than 73% 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.
