Detailsinfo

A vulnerability was found in IEEE P1735 (unknown version) and classified as critical. This issue affects an unknown code block. 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. 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 improperly specified HDL syntax allows use of an EDA tool as a decryption oracle. 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 shared 07/13/2018 as confirmed advisory (CERT.org). The advisory is shared at kb.cert.org. The identification of this vulnerability is CVE-2017-13092 since 08/22/2017. An attack has to be approached locally. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1600 for this issue.

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-121470, VDB-121471 and VDB-121472 are related to this item. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
