CVE-2010-2952: Apache Traffic Server

Medium severity, CVSS 4.3. EPSS: 2.6% chance of exploitation in the next 30 days.

Apache Traffic Server before 2.0.1, and 2.1.x before 2.1.2-unstable, does not properly choose DNS source ports and transaction IDs, and does not properly use DNS query fields to validate responses, which makes it easier for man-in-the-middle attackers to poison the internal DNS cache via a crafted response.

Affected products

• Apache Traffic Server: up to and including 2.0.0; version 2.1.0 only; version 2.1.1 only
