CVE-2023-26048 Details
Jetty is a java based web server and servlet engine. In affected versions servlets with multipart support (e.g. annotated with `@MultipartConfig`) that call `HttpServletRequest.getParameter()` or `HttpServletRequest.getParts()` may cause `OutOfMemoryError` when the client sends a multipart request with a part that has a name but no filename and very large content. This happens even with the default settings of `fileSizeThreshold=0` which should stream the whole part content to disk. An attacker client may send a large multipart request and cause the server to throw `OutOfMemoryError`. However, the server may be able to recover after the `OutOfMemoryError` and continue its service -- although it may take some time. This issue has been patched in versions 9.4.51, 10.0.14, and 11.0.14. Users are advised to upgrade. Users unable to upgrade may set the multipart parameter `maxRequestSize` which must be set to a non-negative value, so the whole multipart content is limited (although still read into memory).

Exploit prediction scoring system (EPSS) score for CVE-2023-26048
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%).
39.41 Probability of exploitation activity being observed over the next 30 days (97th percentile)
CVSS score for CVE-2023-26048
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.
