CVE-2006-6893

UnknownEPSS 2.11%

Last modified

CVE-2006-6893 is a vulnerability of currently unknown severity. Tor allows remote attackers to discover the IP address of a hidden service by accessing this service at a high rate, thereby changing the server's CPU temperature and consequently changing the pattern of time values visible through (1) ICMP timestamps, (2) TCP sequence numbers, and (3) TCP timestamps, a different vulnerability than CVE-2006-0414. NOTE: it could be argued that this is a laws-of-physics vulnerability that is a fundamental design limitation of certain hardware implementations, so perhaps this issue should not be included in CVE.. EPSS estimates a 2.11% chance of exploitation in the next 30 days.
