CVE-2024-55451

Exp

A Stored Cross-Site Scripting (XSS) vulnerability exists in authenticated SVG file upload and viewing functionality in UJCMS 9.6.3. The vulnerability arises from insufficient sanitization of embedded attributes in uploaded SVG files. When a maliciously crafted SVG file is viewed by other backend users, it allows authenticated attackers to execute arbitrary JavaScript in the context of other backend users' browsers, potentially leading to the theft of sensitive tokens.

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:H)
They need powerful rights—admin, root, or similar—before this pays off.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
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:N)
Service keeps running; no real outage angle.
