Description

Summary

A vulnerability exists in the Create User process, allowing the creation of a new admin account with an option to upload a profile image. An attacker can upload a malicious SVG file containing an embedded script. When the profile image is accessed, the embedded script executes, leading to the potential theft of session cookies.

  1. Login as admin
  2. Go to Create User
  3. Fill up everything in the registration form then upload SVG image as a profile picture
  4. In SVG image, add script tag to prepare for XSS attack
  5. Complete the Create User process
  6. Right click at the image to obtain image URL address
  7. XSS triggered

7.3 3.1 —
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
