CVE-2009-0654

Tor 0.2.0.28, and probably 0.2.0.34 and earlier, allows remote attackers, with control of an entry router and an exit router, to confirm that a sender and receiver are communicating via vectors involving (1) replaying, (2) modifying, (3) inserting, or (4) deleting a single cell, and then observing cell recognition errors at the exit router. NOTE: the vendor disputes the significance of this issue, noting that the product's design "accepted end-to-end correlation as an attack that is too expensive to solve."

Methodology and limits

Source-backed, but still worth verifying for high-impact use.

Security records are triage intelligence and should be validated against asset inventory, firmware versions, compensating controls, and vendor advisories.

For security teams

Prioritize known exploited and high-confidence records.

For buyers

Check support and vulnerability signals before purchase.

For MSPs

Use reports and monitors for customer device review.

Questions to ask before relying on this record

Paid reports include citation paths and report-generation context; public previews intentionally hide source URLs.
