标题： Cisco node-jose open source library 数据伪造问题漏洞 (CVE-2018-0114)
描述：Cisco node-jose open source library是美国思科（Cisco）公司的一个基于Web浏览器和node.js的服务器的JSON对象签名和加密的开源库。 Cisco node-jose open source library 0.11.0之前的版本中存在安全漏洞，该漏洞源于node-jose使用了JSON Web Signature (JWS)标准。远程攻击者可通过移除原签名伪造有效的JWS对象利用该漏洞重新签名令牌。
描述
POC for CVE-2018-0114 written in Go
介绍
# CVE-2018-0114 POC

A vulnerability in the Cisco node-jose open source library before 0.11.0 could allow an unauthenticated, remote attacker to re-sign tokens using a key that is embedded within the token. The vulnerability is due to node-jose following the JSON Web Signature (JWS) standard for JSON Web Tokens (JWTs). This standard specifies that a JSON Web Key (JWK) representing a public key can be embedded within the header of a JWS. This public key is then trusted for verification. An attacker could exploit this by forging valid JWS objects by removing the original signature, adding a new public key to the header, and then signing the object using the (attacker-owned) private key associated with the public key embedded in that JWS header.
