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 Java OpenWire protocol marshaller is vulnerable to Remote Code
Execution. This vulnerability may allow a remote attacker with network
access to either a Java-based OpenWire broker or client to run arbitrary
shell commands by manipulating serialized class types in the OpenWire
protocol to cause either the client or the broker (respectively) to
instantiate any class on the classpath.
Users are recommended to upgrade
both brokers and clients to version 5.15.16, 5.16.7, 5.17.6, or 5.18.3
which fixes this issue.
CVSS Base Score: 10.0 (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: 0.9444
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: 0.9999
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
