Detailsinfo

A vulnerability was found in Huawei Home Gateway WS318 up to V100R001C01B022. It has been classified as problematic. This affects an unknown functionality of the component Random Number Generator. The manipulation with an unknown input leads to a entropy vulnerability. CWE is classifying the issue as CWE-332. The lack of entropy available for, or used by, a Pseudo-Random Number Generator (PRNG) can be a stability and security threat. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Huawei home gateways WS318 with software V100R001C01B022 and earlier versions are affected by the PIN offline brute force cracking vulnerability of the WPS protocol because the random number generator (RNG) used in the supplier's solution is not random enough. As a result, brute force cracking the PIN code is easier. After an attacker cracks the PIN, the attacker can access the Internet via the cracked device.

The bug was discovered 12/24/2014. The weakness was disclosed 04/02/2017 (Website). The advisory is shared at huawei.com. This vulnerability is uniquely identified as CVE-2014-9690 since 03/13/2015. The exploitability is told to be difficult. An attack has to be approached locally. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1600.001 for this issue.

The vulnerability was handled as a non-public zero-day exploit for at least 830 days. During that time the estimated underground price was around $0-$5k.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
