Kerentanan Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') pada cesanta mongoose. Skor CVSS 3.1 5.4 (Medium) menurut github.com.

Deskripsi (NVD)

Mongoose is an embedded web server and network library. Prior to 7.22, a remote attacker can send a crafted percent-encoded request path to a deployment using MG_ENABLE_DIRLIST and persuade a user to visit it. The mg_http_serve_dir() and listdir() path in src/http.c places the decoded request URI into the title and h1 elements without HTML entity encoding. The resulting reflected cross-site scripting executes in the Mongoose origin and can expose session data or perform actions as the victim. This issue is fixed in version 7.22.
