CVE-2020-10280
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 · uneditedThe Apache server on port 80 that host the web interface is vulnerable to a DoS by spamming incomplete HTTP headers, effectively blocking the access to the dashboard.
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 confidenceThe Apache HTTP Server listening on port 80 that hosts the web interface is vulnerable to a denial-of-service attack. An attacker can send multiple incomplete HTTP headers to exhaust server resources and block access to the dashboard.

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 device model and firmware versionAccess the device admin panel or use the command line interface to retrieve the exact model number (e.g., Mir100, Mir200, Mir250, Mir500, Mir1000, Er200, Er Lite, Er Flex) and firmware version. On Mir robots, this is typically found in the web interface under 'System' or 'Settings' or via the robot's local display.Affected if The device is a Mir100 with firmware <= 2.8.1.1, or any Mir200, Mir250, Mir500, Mir1000, Er200, Er Lite, or Er Flex regardless of firmware version.
-
Verify Apache HTTP Server is running on port 80Attempt to access the device web interface by browsing to http://[device-ip]:80 or http://[device-ip]. Check if the Apache landing page or robot dashboard loads. You can also run 'netstat -an | grep :80' or 'curl -v http://localhost:80' from the device console if you have shell access.Affected if The Apache server on port 80 is exposed and reachable.
-
Check Apache configuration for header handling settingsIf you have console or SSH access to the device, examine the Apache configuration files (typically in /etc/apache2/ or /etc/httpd/). Look for directives related to TimeOut, LimitRequestFields, LimitRequestFieldSize, and Header parsing behavior.Affected if The Apache configuration lacks proper timeout limits or request field restrictions for handling incomplete headers.
-
Test for vulnerability with crafted incomplete headersSend incomplete HTTP headers to the device using a tool like netcat: 'echo -e "GET / HTTP/1.1\r\nHost: target\r\n" | nc target 80'. Repeat this multiple times and observe if the server becomes unresponsive or exhibits delayed responses.Affected if The server becomes slow, unresponsive, or drops connections after receiving incomplete headers.
A user is affected if they have a Mir100 device on firmware 2.8.1.1 or lower, or any Mir200, Mir250, Mir500, Mir1000, Er200, Er Lite, or Er Flex device with the web interface (Apache on port 80) accessible, and the Apache configuration does not enforce strict header timeout and field limits.

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 Apache request filtering and timeout configurations to drop incomplete headers; consider rate limiting or a WAF in front of the Apache server.
