Detailsinfo

A vulnerability, which was classified as critical, has been found in Pirelli Router P.DG-A4001N (Router Operating System). This issue affects some unknown processing of the component WPA Key Handler. The manipulation with an unknown input leads to a missing encryption vulnerability. Using CWE to declare the problem leads to CWE-311. The product does not encrypt sensitive or critical information before storage or transmission. Impacted is integrity.

The bug was discovered 09/11/2014. The weakness was released 01/06/2015 by Eduardo Pablo Novella Lorente (@enovella_) with Universitat Politècnica de València as Reverse-engineering the default WPA key generation algorithm for Pirelli routers in Argentina as confirmed article (Website). The advisory is shared at ednolo.alumnos.upv.es. The public release happened without involvement of Pirelli. The identification of this vulnerability is CVE-2015-0558 since 01/05/2015. The exploitation is known to be easy. Access to the local network is required for this attack to succeed. No form of authentication is needed for a successful exploitation. Technical details are unknown but a public exploit is available. MITRE ATT&CK project uses the attack technique T1600 for this issue.

A public exploit has been developed by Eduardo Pablo Novella Lorente in Python. The exploit is available at packetstormsecurity.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 117 days. During that time the estimated underground price was around $0-$5k. The advisory illustrates:

Just to see how easy was to achieve those keys in the HomeStation(essids-like WLAN_XXXX) in Spain, a simple curl command was enough (...)

The article contains the following remark:

Since I attempted to do a responsible disclosure and neither ADB Pirelli nor Arnet Argentina were interested to discuss the problem, I have finally decided to do full disclosure to speed up the process of fixing.

The vulnerability is also documented in the vulnerability database at X-Force (99682). ednolo.alumnos.upv.es is providing further details. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
