CVE-2023-50291 Details
Insufficiently Protected Credentials vulnerability in Apache Solr.

This issue affects Apache Solr: from 6.0.0 through 8.11.2, from 9.0.0 before 9.3.0.
One of the two endpoints that publishes the Solr process' Java system properties, /admin/info/properties, was only setup to hide system properties that had "password" contained in the name.
There are a number of sensitive system properties, such as "basicauth" and "aws.secretKey" do not contain "password", thus their values were published via the "/admin/info/properties" endpoint.
This endpoint populates the list of System Properties on the home screen of the Solr Admin page, making the exposed credentials visible in the UI.

This /admin/info/properties endpoint is protected under the "config-read" permission.
Therefore, Solr Clouds with Authorization enabled will only be vulnerable through logged-in users that have the "config-read" permission.
Users are recommended to upgrade to version 9.3.0 or 8.11.3, which fixes the issue.
A single option now controls hiding Java system property for all endpoints, "-Dsolr.hiddenSysProps".
By default all known sensitive properties are hidden (including "-Dbasicauth"), as well as any property with a name containing "secret" or "password".

Users who cannot upgrade can also use the following Java system property to fix the issue:
  '-Dsolr.redaction.system.pattern=.*(password|secret|basicauth).*'

Exploit prediction scoring system (EPSS) score for CVE-2023-50291
EPSS (Exploit Prediction Scoring System): EPSS predicts the likelihood that a vulnerability will be exploited in the wild. A higher percentage means a greater chance of an exploit occurring. The EPSS model produces a probability score between 0 and 1 (0 and 100%).
0.5 Probability of exploitation activity being observed over the next 30 days (65th percentile)
CVSS score for CVE-2023-50291
CVSS (Common Vulnerability Scoring System): An open framework owned and managed by FIRST.Org, Inc. that assigns a numerical score from 0 to 10 to software vulnerabilities to indicate their severity.

Bitsight Data Discovery and Continuous Threat Scanning

Bitsight, the leading provider in Cyber Risk Management, introduced the next-generation internet scanner Bitsight Groma in May 2024. This technology continuously scans the entire internet to discover assets, collect asset attribution evidence, and identify an ever-growing set of security observations, such as vulnerabilities and misconfigurations. Groma’s scanning activities presently encompass:


  • 40 million-plus monitored organizations
  • 250 million-plus host names
  • 4 billion-plus routable IPv4 and IPv6 addresses

Greynoise’s recent study testifies the speed of Bitsight Groma.
