Detailsinfo

A vulnerability was found in IEEE P1735 (affected version unknown). It has been rated as critical. Affected by this issue is an unknown functionality. The manipulation with an unknown input leads to a cryptographic issue vulnerability. Using CWE to declare the problem leads to CWE-310. Impacted is confidentiality, integrity, and availability. CVE summarizes:

The P1735 IEEE standard describes flawed methods for encrypting electronic-design intellectual property (IP), as well as the management of access rights for such IP, including modification of a license-deny response to a license grant. The methods are flawed and, in the most egregious cases, enable attack vectors that allow recovery of the entire underlying plaintext IP. Implementations of IEEE P1735 may be weak to cryptographic attacks that allow an attacker to obtain plaintext intellectual property without the key, among other impacts.

The bug was discovered 11/03/2017. The weakness was disclosed 07/13/2018 as confirmed advisory (CERT.org). The advisory is shared for download at kb.cert.org. This vulnerability is handled as CVE-2017-13095 since 08/22/2017. The attack needs to be approached locally. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1600.

The vulnerability was handled as a non-public zero-day exploit for at least 252 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.

The vulnerability is also documented in the vulnerability database at SecurityFocus (BID 101699†). The entries VDB-121468, VDB-121469, VDB-121470 and VDB-121471 are pretty similar. VulDB is the best source for vulnerability data and more expert information about this specific topic.
