CVE-2007-1103: Tor

Medium severity, CVSS 4.3. EPSS: 1.8% chance of exploitation in the next 30 days.

Tor does not verify a node's uptime and bandwidth advertisements, which allows remote attackers who operate a low resource node to make false claims of greater resources, which places the node into use for many circuits and compromises the anonymity of traffic sources and destinations.

Affected products

• Tor Tor: up to and including 0.1.1.26
