CVE-2019-9555 describes a weak WPA Pre-Shared Key (PSK) generation vulnerability in Sagemcom F@st 5260 routers running firmware version 0.4.39. The PSK is derived from a limited wordlist and a low-entropy nonce, resulting in approximately 1.78 billion possible keys, which is insufficient for robust security. This medium-severity vulnerability (CVSS 5.3) allows an unauthenticated attacker to potentially recover the PSK, leading to a loss of confidentiality. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
