[Eclipse Vert.x] Stored Cross-site Scripting in directory listings via file names
The Eclipse Foundation is a Common Vulnerabilities and Exposures (CVE) Numbering Authority. This issue it used to request and track the progress of the assignment of a CVE for a vulnerability in the project code for an Eclipse open source project.
Basic information
Project name: Eclipse Vert.x
Project id: rt.vertx
Request type: publication
Versions affected: [4.0.0, 4.5.21] and [5.0.0, 5.0.4]
Common Weakness Enumeration:
- CWE-79 Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting')
- CWE-80 Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS)
Common Vulnerability Scoring System: CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N
Summary:
In Eclipse Vert.x versions [4.0.0, 4.5.21] and [5.0.0, 5.0.4], when "directory listing" is enabled, file and directory names are inserted into generated HTML without proper escaping in the href, title, and link attributes. An attacker who can create or rename files or directories within a served path can craft filenames containing malicious script or HTML content, leading to stored cross-site scripting (XSS) that executes in the context of users viewing the affected directory listing.
