Vulnerability from variot
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. GoAhead for, Capture-replay An authentication bypass vulnerability exists.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. GoAhead is the world's most popular, tiny embedded web server. It is compact, secure and simple to use. GoAhead is deployed in hundreds of millions of devices and is ideal for the smallest of embedded devices.A security vulnerability affecting GoAhead versions 2 to 5 has been identified when using Digest authentication over HTTP. GoAhead versions 3 to 5 validated the nonce with a fixed duration of 5 minutes which permitted short-period replays. This duration is too long for most implementations.Tested on: GoAhead-httpGoAhead-Webs. There is a security vulnerability in Embedthis Software GoAhead versions before 5.1.2. An attacker could exploit this vulnerability to bypass authentication
