CVE-2024-25657
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn open redirect in the Login/Logout functionality of web management in AVSystem Unified Management Platform (UMP) 23.07.0.16567~LTS could allow attackers to redirect authenticated users to malicious websites.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceOpen redirect vulnerability in AVSystem UMP web management's login/logout functionality allows authenticated users to be redirected to attacker-controlled websites via unvalidated redirect parameters.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify AVSystem UMP installationCheck for AVSystem UMP web management interface by accessing the management portal URL (commonly /ump, /admin, or the default web interface port 443/8080). Look for AVSystem branding or ump-related processes running on the system.Affected if AVSystem UMP web management interface is present and accessible
-
Determine UMP versionCheck the installed UMP version via the web interface footer, admin panel 'About' section, or by querying the service/process version (common locations: /opt/avsystem/ump, /usr/share/ump, or via 'dpkg -l'/'rpm -qi' if installed via package manager).Affected if The installed version matches or predates the vulnerable release where the open redirect was present (confirm against vendor release notes for when the fix was applied)
-
Verify login page accepts redirect parameterAccess the UMP login page and inspect the request/response. Look for redirect, next, url, or callback parameters in the URL query string. Example: /login?redirect=http://evil.comAffected if The login page accepts and reflects a redirect parameter without strict validation of the destination domain
-
Test logout for unvalidated redirectsLogout from the UMP interface and inspect the logout URL for redirect parameters. Example: /logout?redirect=https://attacker.com. Attempt a logout and observe if the browser is redirected to an arbitrary domain.Affected if The logout function allows an attacker-controlled URL to be used as the redirect target without sanitization
-
Confirm authentication requirementVerify that exploitation requires a valid authenticated session. Attempt the redirect with and without valid credentials.Affected if The redirect vulnerability is exploitable only by authenticated users (as stated in the CVE description)
The environment is affected if AVSystem UMP web management is installed and the login/logout functionality reflects unvalidated redirect parameters, allowing authenticated users to be redirected to arbitrary external URLs.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict validation of redirect URLs to ensure only relative paths or explicitly whitelisted domains are permitted; reject or sanitize any user-supplied redirect parameters before use.
