This 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: A missing authentication vulnerability in dulldusk/phpfm through 1.8.0 allows an unauthenticated remote attacker to access the full file manager functionality including reading, writing, deleting, and uploading files anywhere on the server filesystem. The authentication check in index.php at line 637 evaluates 'if ($auth_pass == '' || $loggedon==$auth_pass)', and since auth_pass is an empty string in the default configuration, the condition always evaluates to true and grants full access without credentials.

CVSS Base Score: 9.8 (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: N/A

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.

EPSS Score not available for this CVE.

Percentile: N/A

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.

Percentile not available for this CVE.
