CVE-2020-29574

Think of Cyberoam OS’s WebAdmin as the “control panel” for your network security device. This bug lets someone skip the login step and trick the device into running its own database commands, which can open the door to total control. Because it’s been seen in real ransomware attacks and there’s no known patch, keeping the device running is a high risk.

This matters to you if your business still uses Cyberoam OS and you allow access to its WebAdmin interface. It’s especially urgent if WebAdmin is reachable from the internet (directly or via exposed network paths), because the flaw can be triggered by unauthenticated attackers. CISA’s guidance indicates this should be treated as a discontinued product risk (EoL/EoS).

This is RED because it’s confirmed in CISA KEV as being used in ransomware campaigns, and it’s a remote, unauthenticated database-injection weakness in WebAdmin. There is no known patch available, and the product is end-of-life/end-of-service, so delaying increases the chance your device is targeted. Treat it as an immediate “stop exposure and replace” situation.

1. Exposure check (fast):

   • Confirm whether the affected device is actually Cyberoam OS running WebAdmin.
   • From a network boundary perspective, verify whether the WebAdmin port/interface is reachable from the public internet (including via port forwarding, DMZ, or a management VPN that allows broad access).

2. If reachable, reduce exposure right now:

   • Remove/undo any port forwarding or inbound rules that expose WebAdmin to the internet.
   • Restrict access to WebAdmin to a minimal set of trusted admin IP addresses and/or a tightly controlled management network.
   • Ensure any “temporary” external access methods (public management URLs, broad VPN access, etc.) are disabled.

3. Replace because no patch is available:

   • Per CISA KEV, the affected product is end-of-life/end-of-service. Since no fix/patch information is available, the practical remediation is to discontinue using Cyberoam OS and migrate to a supported, vendor-patched alternative.
   • During migration, keep the replacement device’s management interface similarly locked down (no internet access).

4. Post-mitigation verification:

   • Review device and security logs for suspicious WebAdmin activity around the period it may have been exposed.
   • Check firewall/security appliance logs for repeated probing of WebAdmin and for any anomalous outbound connections from the device.
   • Confirm that the network no longer has any path that would allow unauthenticated access to WebAdmin.

5. Time guidance from CISA KEV:

   • CISA KEV remediation due date listed for this issue was 2025-02-27; treat that as already elapsed and prioritize replacement and exposure shutdown immediately.

CVE-2020-29574 is a CWE-89 (SQL injection) vulnerability in the WebAdmin component of Cyberoam OS (affecting versions through 2020-12-04). The key mechanism is unauthenticated remote attackers sending crafted input that causes the application to execute arbitrary SQL statements, enabling high impact outcomes such as compromise, disruption, and potential data exposure. CISA KEV confirms real-world abuse: it is listed as being used in ransomware campaigns, which makes this actively relevant despite the absence of a public exploit code record. A patch is not available per the provided findings, and CISA indicates the product is end-of-life/end-of-service, recommending users discontinue utilization. Press attention is sustained, but the decisive urgency driver here is KEV-listed exploitation in the wild. EPSS is a prediction (trend flat) and is not used to downplay risk because KEV/real-world exploitation takes precedence.
