Kerentanan Reusing a Nonce, Key Pair in Encryption pada gnome libsoup, redhat enterprise linux. Skor CVSS 3.1 7.3 (High) menurut NVD.

Deskripsi (NVD)

A flaw was found in Libsoup. The server-side digest authentication implementation in the SoupAuthDomainDigest class does not properly track issued nonces or enforce the required incrementing nonce-count (nc) attribute. This vulnerability allows a remote attacker to capture a single valid authentication header and replay it repeatedly. Consequently, the attacker can bypass authentication and gain unauthorized access to protected resources, impersonating the legitimate user.
