# Vulnerability scan on the Security Management Server shows that port 8211 uses weak HMAC algorithms

**Product:** Security Management  
**Version:** R80.40 (EOS), R81 (EOS), R81.10 (EOS), R81.20, R82  
**OS:** Gaia  
**Last Modified:** 2026-01-21

## Symptoms

- Vulnerability scan on the Security Management Server or Log Server shows that port 8211 uses a weak Hash-based Message Authentication Code cipher suite in TLS 1.2:

`TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA`
  
Port 8211 is used for internal communication between Log Servers for RFL queries.

## Solution

This problem was fixed. The fix is included starting from:

- [Jumbo Hotfix Accumulator for R82](https://sc1.checkpoint.com/documents/Jumbo_HFA/R82/Default.htm) starting from Take 44
- [Jumbo Hotfix Accumulator for R81.20](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.20/Default.htm) starting from Take 119

Check Point recommends to always upgrade to the [Recommended version](https://support.checkpoint.com/results/sk/sk95746) ( [Security Gateway](https://support.checkpoint.com/product/73) / [VSX](https://support.checkpoint.com/product/359) / [Security Management Server](https://support.checkpoint.com/product/184) / [Multi-Domain Security Management Server](https://support.checkpoint.com/product/166) / [SmartConsole](https://support.checkpoint.com/product/191)).

If you choose not to upgrade, [contact Check Point Support](https://www.checkpoint.com/support-services/contact-support/) to get a Hotfix for your version.

A Support Engineer will make sure the Hotfix is compatible with your environment before providing it.

For faster resolution and verification, collect these files:

1. [CPinfo](https://support.checkpoint.com/results/sk/sk92739) file from the Management Server involved in the case.
2. [CPinfo](https://support.checkpoint.com/results/sk/sk92739) file from the Security Gateway / each Cluster Member involved in the case.

**Hotfix installation instructions:**

Refer to [sk168597 - How to install a Hotfix](https://support.checkpoint.com/results/sk/sk168597).

**Note:** You must install the Hotfix on all the Security Management Servers and Log Servers in order not to break the communication between them over TCP port 8211.

#### NOTE

This solution has been verified for the specific scenario, described by the combination of Product, Version and Symptoms. It may not work in other scenarios.
