CVE-2020-15688: Embedthis GoAhead

High severity, CVSS 8.8. EPSS: 4% chance of exploitation in the next 30 days.

The HTTP Digest Authentication in the GoAhead web server before 5.1.2 does not completely protect against replay attacks. This allows an unauthenticated remote attacker to bypass authentication via capture-replay if TLS is not used to protect the underlying communication channel.

Affected products

• Embedthis GoAhead: before 5.1.2 (fixed in 5.1.2)
