Vulnerability Title
GoRest: InMemorySecret2FA race condition allows process crash via concurrent map access
Source: CVE Program / CVE List V5
Vulnerability Description
GoRest is a Golang starter kit built with the Gin framework for prototyping and developing RESTful APIs. In versions prior to 1.12.2 nMemorySecret2FA contains a race condition due to an unsynchronized package-level map used to store 2FA secrets. Multiple HTTP handlers in handler/login.go and handler/twoFA.go read from and write to this map concurrently, and because Go's runtime treats unsynchronized concurrent map access as an unrecoverable fatal error, an attacker can repeatedly trigger this condition to crash the process on demand. This results in high, repeatable availability impact with no confidentiality or integrity consequences. This issue has been fixed in version 1.12.2.

Vulnerability Description
mahir gorest是mahir个人开发者开源的一款基于Go语言的RESTful API框架。 mahir gorest 1.12.2之前版本存在竞争条件问题漏洞，该漏洞源于nMemorySecret2FA中的竞争条件，由于未同步的包级映射存储2FA密钥，多个HTTP处理程序并发读写该映射，攻击者可反复触发导致进程崩溃，造成高可用性影响。
