Ruby OpenSSL Extension inadequate encryption

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.

Summaryinfo

A vulnerability marked as critical has been reported in Ruby. This vulnerability affects unknown code of the component OpenSSL Extension. Performing a manipulation results in inadequate encryption. This vulnerability is known as CVE-2011-4121. Remote exploitation of the attack is possible. No exploit is available.

Detailsinfo

A vulnerability, which was classified as critical, was found in Ruby (Programming Language Software) (the affected version is unknown). This affects an unknown code of the component OpenSSL Extension. The manipulation with an unknown input leads to a inadequate encryption vulnerability. CWE is classifying the issue as CWE-326. The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The OpenSSL extension of Ruby (Git trunk) versions after 2011-09-01 up to 2011-11-03 always generated an exponent value of '1' to be used for private RSA key generation. A remote attacker could use this flaw to bypass or corrupt integrity of services, depending on strong private RSA keys generation mechanism.

The weakness was published 11/26/2019. This vulnerability is uniquely identified as CVE-2011-4121 since 10/18/2011. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1600 for this issue.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
