IEEE P1735 cryptographic issue

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability has been found in IEEE P1735 (the affected version is unknown) and classified as critical. This vulnerability affects an unknown code. The manipulation with an unknown input leads to a cryptographic issue vulnerability. The CWE definition for the vulnerability is CWE-310. As an impact it is known to affect 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 improperly specified padding in CBC mode 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 presented 07/13/2018 as confirmed advisory (CERT.org). The advisory is shared for download at kb.cert.org. This vulnerability was named CVE-2017-13091 since 08/22/2017. The attack needs to be approached locally. No form of authentication is required for a successful 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†). See VDB-121469, VDB-121470, VDB-121471 and VDB-121472 for similar entries. Once again VulDB remains the best source for vulnerability data.
