View the latest critical CVEs issuedThis is a free service offered by Red Hot Cyber to the community. It allows you to view, on a single page, information about a single CVE from the National Vulnerability Database (NVD) and the National Institute of Standards and Technology (NIST) of the United States of America, the Forum of Incident Response and Security Teams (FIRST) regarding the EPSS score and percentile, data from the KEV catalog of the Cybersecurity and Infrastructure Security Agency (CISA), as well as selected resources from Red Hot Cyber and other international sources.
National Vulnerability Database Information
Description: The driver in Micro-Star MSI Afterburner 4.6.2.15658 (aka RTCore64.sys and RTCore32.sys) allows any authenticated user to read and write to arbitrary memory, I/O ports, and MSRs. This can be exploited for privilege escalation, code execution under high privileges, and information disclosure. These signed drivers can also be used to bypass the Microsoft driver-signing policy to deploy malicious code.
CVSS Base Score: 7.8 (v3.1)
The CVSS Base Score is a score from 0 to 10 that represents the intrinsic severity of a vulnerability. A higher score indicates greater severity.

FIRST Information
EPSS Score: 0.1819
The EPSS (Exploit Prediction Scoring System) is a score from 0 to 1 that indicates the probability that a vulnerability will be exploited in the real world in the next 30 days. A higher value indicates a greater likelihood of exploitation.
0.00.250.50.751.0
Percentile: 0.9706
The Percentile indicates how much higher this vulnerability's EPSS score is compared to all other vulnerabilities in the EPSS database. For example, a percentile of 0.90 (90%) means that 90% of vulnerabilities have an EPSS score equal to or lower than the current one.
0.00.250.50.751.0

CISA Information (Known Exploited Vulnerabilities)
The CISA KEV Catalog lists vulnerabilities that have been actively exploited in the real world. If a CVE is present in this catalog, it indicates that the threat is immediate and mitigation should be a top priority.
CVE CVE-2019-16098 is not present in the CISA KEV Catalog. This indicates that it is not currently classified by CISA as an actively exploited vulnerability.

- VortexCry-Organization/VortexCry-Ransomware-Release: # VortexCry-Ransomware VortexCry is an advanced ransomware that utilizes multi-stage process injection (such as Process Hollowing and APC Injection) and kernel driver loading (via the CVE-2019-16098 vulnerability). It is capable of encrypting files, destroying system recovery functionalities, and demanding a ransom.
- CrowTheArchfiend/RTCore64-probe: A tiny cpp program to test reading memory using a vulnerable RTCore64.sys driver/device (CVE-2019-16098). It tries to read a "secret" from its own memory using the driver, to test if the handle has been closed. This requires the RTCore64.sys driver to be loaded before execution!
