CyberRota Analysis
AI-GeneratedBoringproxy versions up to 0.10.0 are vulnerable to a newline injection flaw that enables authenticated low-privileged users with tunnel-creation permissions to manipulate the SSH authorized_keys file. This vulnerability allows attackers to insert arbitrary public keys, granting them persistent shell access and the ability to extract sensitive credentials, including user tokens and TLS certificates, from the database. Organizations using Boringproxy should prioritize patching this vulnerability to prevent potential exploitation and data breaches.

Original NVD Description
boringproxy through 0.10.0 contains a newline injection vulnerability that allows authenticated low-privileged users with tunnel-creation permission to inject arbitrary lines into the server account's SSH authorized_keys file by supplying a percent-encoded newline character in the domain parameter of the tunnel creation endpoint. Attackers can insert an unrestricted public key entry into authorized_keys to gain persistent shell access, and subsequently read cleartext credentials from the database file including all user tokens, tunnel private keys, and TLS certificates.
