CVE-2019-11873

wolfSSL 4.0.0 has a Buffer Overflow in DoPreSharedKeys in tls13.c when a current identity size is greater than a client identity size. An attacker sends a crafted hello client packet over the network to a TLSv1.3 wolfSSL server. The length fields of the packet: record length, client hello length,...

Sagemcom [email protected] 5260 Router Insufficient Default PSK Entropy Vulnerability

Sagemcom email protected 5260 routers on firmware version 0.4.39 and possibly others, in WPA mode, default to using a PSK that is generated from a 2-part wordlist of known values and a nonce with insufficient entropy. The number of possible PSKs is about 1.78 billion, which is too small. 0day.tod...

CVE-2019-9555

CVE-2019-9555 affects Sagemcom F@st 5260 routers (firmware 0.4.39 and possibly others) where WPA PSKs are derived from a two-part wordlist plus a nonce with insufficient entropy. This yields roughly 1.78 billion possible PSKs, making the WPA key space far smaller than expected and enabling potent...

CVE-2018-5389

CVE-2018-5389 concerns the IKEv1 main mode with Pre-Shared Keys (PSK). The vulnerability allows an offline dictionary/brute-force attack to recover a weak PSK and can enable impersonation of a host or network, particularly when PSKs are reused across versions/modes. Cross-protocol authentication ...

CVE-2018-5389

The Internet Key Exchange v1 main mode is vulnerable to offline dictionary or brute force attacks. Reusing a key pair across different versions and modes of IKE could lead to cross-protocol authentication bypasses. It is well known, that the aggressive mode of IKEv1 PSK is vulnerable to offline...

Hijacking Philips Hue

We were filming a smart home hacking piece on the 5th May this year. Like most home users, the Wi-Fi PSK wasn’t strong enough, so we cracked it and joined the network. The user had a Philips Hue lighting system. None of us here had looked at Hue before - we made an assumption after the previous...
