CVE-2024-31213 | InstantCMS Open Redirect vulnerability

Exp

InstantCMS is a free and open source content management system. An open redirect was found in the ICMS2 application version 2.16.2 when being redirected after modifying one's own user profile. An attacker could trick a victim into visiting their web application, thinking they are still present on the ICMS2 application. They could then host a website stating "To update your profile, please enter your password," upon which the user may type their password and send it to the attacker. As of time of publication, a patched version is not available.

Base score Version Severity Vector Exploitability Impact Score source
3.5 3.1 LOW
CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:N 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:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
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.

Some sensitive info could get out, but not a total data dump.
