Infineon RSA Library up to 1.02.013 RSA Key Generation 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 Infineon RSA Library up to 1.02.013 (Software Library) and classified as critical. This vulnerability affects some unknown functionality of the component RSA Key Generation. 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 Infineon RSA library 1.02.013 in Infineon Trusted Platform Module (TPM) firmware, such as versions before 0000000000000422 - 4.34, before 000000000000062b - 6.43, and before 0000000000008521 - 133.33, mishandles RSA key generation, which makes it easier for attackers to defeat various cryptographic protection mechanisms via targeted attacks, aka ROCA. Examples of affected technologies include BitLocker with TPM 1.2, YubiKey 4 PGP key generation, and the Cached User Data encryption feature in Chrome OS.

The bug was discovered 10/10/2017. The weakness was shared 10/16/2017 (Website). The advisory is available at support.lenovo.com. This vulnerability was named CVE-2017-15361 since 10/15/2017. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1600 by the MITRE ATT&CK project.

The vulnerability was handled as a non-public zero-day exploit for at least 6 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 103864 (SSL Certificate Contains Weak RSA Key (Infineon TPM / ROCA)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family General and running in the context r. The commercial vulnerability scanner Qualys is able to test this issue with plugin 42042 (Detection of certificates with vulnerable keys 2 (ROCA)).

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the databases at Tenable (103864) and SecurityFocus (BID 101484†). If you want to get best quality of vulnerability data, you may have to visit VulDB.
