CVE-2021-32066: Oracle Jd Edwards Enterpriseone Tools

High severity, CVSS 7.4. EPSS: 2.9% chance of exploitation in the next 30 days.

An issue was discovered in Ruby through 2.6.7, 2.7.x through 2.7.3, and 3.x through 3.0.1. Net::IMAP does not raise an exception when StartTLS fails with an an unknown response, which might allow man-in-the-middle attackers to bypass the TLS protections by leveraging a network position between the client and the registry to block the StartTLS command, aka a "StartTLS stripping attack."

Affected products

• Oracle Jd Edwards Enterpriseone Tools: before 9.2.6.1 (fixed in 9.2.6.1)
• Ruby-Lang Ruby: from 2.6.0, up to and including 2.6.7; from 2.7.0, up to and including 2.7.3; from 3.0.0, up to and including 3.0.1
