A vulnerability was found in IEEE P1735 (version unknown). It has been declared as critical. Affected by this vulnerability is an unknown function. The manipulation with an unknown input leads to a cryptographic issues vulnerability. The CWE definition for the vulnerability is CWE-310. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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 the encryption key and insertion of hardware trojans in any IP. 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 released 07/13/2018 as confirmed advisory (CERT.org). It is possible to read the advisory at kb.cert.org. This vulnerability is known as CVE-2017-13094 since 08/22/2017. Attacking locally is a requirement. The exploitation doesn't need any form of authentication. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1600 according to MITRE ATT&CK.

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†). Entries connected to this vulnerability are available at VDB-121468, VDB-121469, VDB-121470 and VDB-121472.
