Upgrade directly to EdgeOne 2.7.12 using the upgrade image on the MyTXOne Portal. |
Mitigation Before Upgrading
Edge Series Devices
- Update to the latest IPS pattern.
- In the device console, go to Admin → System → Edge Device Security.
- Under IPS for Self-Protection, enable Apply IPS profiles to secure Edge device.
- Select the IPS profile and click Save.

EdgeOne, ODC, and TPS
| Product | Recommended action |
|---|---|
| EdgeOne | Update to self-protection pattern TXv2_SDP_261030_1 or later. |
| ODC | Upgrade to ODC 1.5 or later and apply the latest self-protection pattern (SDP_261030_15 for ODC-VA). Alternatively, migrate to EdgeOne 2.7.12 or later and enable self-protection with pattern TXv2_SDP_261030_1. |
| TPS | Apply self-protection pattern SDP_261030_15. |
Threat Coverage
Check Pattern Versions on the MyTXOne Portal for the latest IPS and VDS patterns.
| Threat | Detection coverage | Recommended action |
|---|---|---|
| PHP2Shell (CVE-2026-109618) |
Five IPS rules and a VDS pattern | Update to the latest IPS and VDS patterns. This coverage is supported across the Edge product family and requires only a pattern update. |
| Node2Shell (Google Brotli, CVE-2026-111497) |
Two IPS rules and a VDS pattern | Update to the latest IPS and VDS patterns. No additional product action is required for this threat. |
| PXE (CVE-2026-97631) |
Four IPS rules. No VDS pattern is available for this threat. | Update to the latest IPS pattern to protect exposed assets behind EdgeIPS or EdgeFire. EdgeIPS and EdgeFire hardware appliances are unaffected by this vulnerability. |
| Linux Kernel TCP (CVE-2026-98432) |
One IPS rule and a VDS pattern | Update the patterns and follow the steps under Mitigation Before Upgrading. Apply the applicable firmware patch or system upgrade when it becomes available. |
