CVE-2025-13819 Overview
CVE-2025-13819 is an open redirect vulnerability [CWE-601] in the web server component of Mobile Industrial Robots (MiR) Robot and Fleet software. A remote attacker can craft a URL containing a malicious redirect parameter that sends authenticated or unauthenticated users to arbitrary external websites. Because the redirect originates from a trusted MiR-hosted URL, victims are more likely to trust the destination, enabling phishing and social engineering campaigns against operators of industrial mobile robots.
Critical Impact
A remote attacker can leverage a trusted MiR web server URL to redirect users to attacker-controlled sites, facilitating credential harvesting and malware delivery against industrial robot operators.
Affected Products
- MiR Robot software (web server component)
- MiR Fleet software (web server component)

Technical Details for CVE-2025-13819
Vulnerability Analysis
The flaw resides in the web server component shipped with MiR Robot and MiR Fleet software. The server accepts a user-supplied parameter that controls the destination of an HTTP redirect response without validating the value against an allow-list of trusted hosts. An attacker constructs a URL on the legitimate MiR web interface that, when clicked, returns an HTTP 3xx response pointing to an external domain.
User interaction is required to trigger the redirect, and the attack crosses a trust boundary by leveraging the legitimate origin of the MiR web server. The vulnerability does not directly affect availability or grant code execution on the robot. Its primary value to an attacker is as a credibility multiplier for phishing, malware staging, and social engineering targeting fleet operators, technicians, and integrators.
Root Cause
The root cause is improper validation of a redirect target supplied through a request parameter, classified as URL Redirection to Untrusted Site [CWE-601]. The application uses the parameter value directly in a Location header or client-side navigation without confirming the destination matches an approved domain.
Attack Vector
Exploitation occurs over the network and requires a victim to click or follow a crafted link. The attacker distributes a URL pointing to the MiR web server with the redirect parameter set to an attacker-controlled domain. The MiR server responds with a redirect, transparently delivering the victim to the malicious site. Common follow-on payloads include cloned MiR login portals for credential capture and drive-by download pages targeting engineering workstations on operational technology (OT) networks.
No verified exploit code or public proof-of-concept is currently available for CVE-2025-13819. See the Mobile Industrial Robots Advisory for vendor-specific technical details.
Detection Methods for CVE-2025-13819
Indicators of Compromise
- HTTP 3xx responses from the MiR web server where the Location header points to an external domain not associated with MiR infrastructure
- Inbound requests to the MiR web server containing redirect parameters with absolute URLs, encoded URLs, or protocol-relative paths such as //attacker.example
- Web proxy or DNS logs showing MiR operator workstations following redirects from MiR hosts to newly registered or low-reputation domains
Detection Strategies
- Inspect web server access logs for query strings containing http://, https://, or %2F%2F sequences in redirect-related parameters
- Correlate referer headers showing the MiR web interface with subsequent connections to external, non-corporate domains
- Deploy URL reputation checks at the network egress layer to flag redirects from internal OT systems to untrusted destinations
Monitoring Recommendations
- Enable verbose HTTP access logging on the MiR web server and forward logs to a central analytics platform
- Monitor authentication failures on the MiR Fleet interface that follow redirect events, which may indicate credential phishing attempts
- Alert on user reports of unexpected login prompts after clicking MiR-hosted links
How to Mitigate CVE-2025-13819
Immediate Actions Required
- Apply the vendor-supplied update referenced in the Mobile Industrial Robots Advisory
- Restrict network access to the MiR Robot and MiR Fleet web interfaces to authorized management VLANs only
- Train operators and technicians to verify the final destination of any link before entering credentials, even when the link originates from a trusted MiR URL
Patch Information
Mobile Industrial Robots has published guidance for this issue. Review the Mobile Industrial Robots Advisory for fixed versions and apply the upgrade to all affected Robot and Fleet deployments. Follow hardening recommendations in the MiR Cybersecurity Guide.
Workarounds
- Place the MiR web interface behind a reverse proxy that rewrites or strips redirect parameters pointing to external domains
- Enforce an outbound web filtering policy on operator workstations to block connections to uncategorized or newly registered domains
- Disable or restrict use of the redirect parameter at the network boundary using a web application firewall rule that blocks absolute URLs in the affected query string
# Example WAF rule concept - block external redirect targets in query strings
# (adapt to your WAF syntax and confirm the exact parameter name with the vendor advisory)
