CVE-2025-0608 Overview
CVE-2025-0608 is an open redirect vulnerability affecting Logo Software Inc.'s Logo Cloud platform. The flaw allows attackers to redirect authenticated users from a trusted Logo Cloud URL to an attacker-controlled destination. Classified under [CWE-601] (URL Redirection to Untrusted Site), the issue enables phishing campaigns and forceful browsing attacks against users of the platform. All Logo Cloud releases prior to version 2025.R6 are affected. The vulnerability was disclosed through the Turkish national cyber security authority (USOM) under advisory TR-25-0318.
Critical Impact
Attackers can craft URLs on the legitimate Logo Cloud domain that redirect victims to malicious sites, enabling credential theft and social engineering attacks against trusted users.

Technical Details for CVE-2025-0608
Vulnerability Analysis
CVE-2025-0608 stems from insufficient validation of user-controlled URL parameters used in redirect logic within Logo Cloud. The application accepts a destination URL and issues an HTTP redirect without verifying that the target belongs to an allowlisted domain. An authenticated user who clicks a specially crafted Logo Cloud link is transparently forwarded to an attacker-controlled host. Because the initial URL resolves to a trusted Logo Cloud domain, users and email security gateways are more likely to treat the link as legitimate. The vulnerability requires low privileges and user interaction over the network.
Root Cause
The root cause is missing or insufficient allowlist validation on a redirect parameter. The application trusts client-supplied input when constructing the Location header response. This pattern maps directly to [CWE-601], URL Redirection to Untrusted Site, commonly known as open redirect.
Attack Vector
An attacker crafts a Logo Cloud URL containing a redirect parameter that points to a malicious domain. The attacker distributes the link through email, chat, or embedded content. When a victim authenticates and follows the link, Logo Cloud issues a redirect to the attacker's site. The attacker can then present a cloned login portal to harvest credentials or deliver malware payloads. Forceful browsing scenarios also allow attackers to bypass intended navigation flows.
No verified proof-of-concept code has been published. See the USOM Security Notification TR-25-0318 for advisory details.
Detection Methods for CVE-2025-0608
Indicators of Compromise
- Outbound web requests originating from Logo Cloud redirects to unfamiliar external domains.
- Email or messaging traffic containing Logo Cloud URLs with encoded url, redirect, next, or return parameters pointing to external hosts.
- Authentication anomalies following user visits to Logo Cloud redirect endpoints, such as credential reuse from atypical geolocations.
Detection Strategies
- Inspect web proxy and secure web gateway logs for HTTP 302 responses from Logo Cloud domains whose Location header targets non-Logo domains.
- Deploy URL parsing rules that flag Logo Cloud requests containing fully qualified external URLs in query string parameters.
- Correlate phishing report submissions with recent user navigation to Logo Cloud redirect endpoints.
Monitoring Recommendations
- Enable phishing telemetry from email security platforms and correlate hits with Logo Cloud referrer strings.
- Monitor DNS resolution logs for lookalike domains that impersonate Logo Cloud login pages.
- Track user reports of unexpected redirects and reauthentication prompts after clicking internal Logo Cloud links.
How to Mitigate CVE-2025-0608
Immediate Actions Required
- Upgrade Logo Cloud to version 2025.R6 or later, which contains the vendor fix.
- Notify user populations to be cautious of Logo Cloud links received via email or external sources until the upgrade is complete.
- Review web gateway policies to block redirects from Logo Cloud domains to uncategorized external hosts.
Patch Information
Logo Software Inc. addressed CVE-2025-0608 in Logo Cloud release 2025.R6. Organizations should coordinate with Logo Software support channels and consult the Siber Güvenlik Advisory TR-25-0318 for authoritative remediation guidance.
Workarounds
- Enforce browser and gateway-level warnings when users are redirected off the Logo Cloud domain.
- Configure email security to rewrite and inspect Logo Cloud URLs, expanding redirect parameters prior to delivery.
- Provide targeted user awareness training that highlights the risk of clicking Logo Cloud links containing embedded external URLs.
