CVE-2023-39678Public exploitNetwork attack vector

Browser script execution via unneutralized logged usernames

Published Aug 29, 2023 · Updated Oct 2, 2024

Stored cross-site scripting in the Log Query page of BDCOM P3310D-2AC 10.1.0F Build 69083 allows remote attackers to run browser scripts. The interface records a Telnet login attempt's username without neutralizing HTML and later renders that value in the Log Query page. Exploitation requires network access to Telnet and a user to view the poisoned log; script execution can read or alter data available to that user's browser session.
