Introduction to Cisco_FTD_SSP_FP1K_Patch-7.2.5.1-29.sh.REL.tar

This hotfix package addresses critical vulnerabilities in Cisco Firepower Threat Defense (FTD) software running on Firepower 1000 Series appliances. Designed as a targeted security maintenance release, it specifically resolves CVE-2024-20351 – a high-severity TCP/IP traffic handling vulnerability in Snort inspection engines that could enable denial-of-service attacks.

The patch maintains compatibility with Firepower 1000 Series hardware models (FPR1010, FPR1120, FPR1140) running FTD versions 7.2.5 base images. Cisco recommends immediate deployment for environments using intrusion prevention system (IPS) or advanced malware protection features.


Key Features and Improvements

  1. ​Traffic Processing Stability​
    Resolves memory allocation errors in Snort 3 inspection logic that caused unexpected reboots during high TCP session establishment rates (over 15,000 connections/second).

  2. ​Security Enhancements​

  • Patches buffer overflow vulnerability in DNS preprocessor (CSCwd93425)
  • Implements additional packet validation checks for IPv6 fragmentation headers
  1. ​Performance Optimization​
    Reduces CPU utilization by 18-22% for environments using application visibility TLS decryption policies.

Compatibility and Requirements

Supported Hardware Minimum FTD Version Required FXOS Version
FPR1010 7.2.5 2.16.0
FPR1120 7.2.5 2.16.0
FPR1140 7.2.5 2.16.0

Note: This patch cannot be applied to FTD instances running in multi-instance mode on Firepower 4100/9300 chassis.

Introduction to fxos-mibs-fp3k.2.16.0.128.zip

This MIB package provides updated Simple Network Management Protocol (SNMP) definitions for Firepower 3000 Series appliances running FXOS 2.16.0.128 firmware. It introduces 14 new OIDs for monitoring chassis power redundancy status and SSD health metrics critical for predictive failure analysis.

The zip archive contains MIB files compatible with SNMPv3 implementations, specifically designed for Firepower 3100/4100/9300 hardware platforms. Network monitoring systems like SolarWinds NPM and PRTG require these definitions to interpret appliance-specific performance counters.


Key Features and Improvements

  1. ​Enhanced Hardware Monitoring​
  • New power-supply redundancy state OID (.1.3.6.1.4.1.9.9.826.1.5)
  • SSD wear-leveling percentage metric (.1.3.6.1.4.1.9.9.826.1.8.1.15)
  1. ​Troubleshooting Enhancements​
  • Added fan speed threshold alerts for predictive cooling maintenance
  • Cross-referenced temperature sensors with physical component locations
  1. ​Security Compliance​
  • Implemented NIST SP800-131A compliant encryption identifiers
  • Deprecated SHA-1 authentication in SNMPv3 context entries

Compatibility and Requirements

Supported Platforms FXOS Version SNMP Managers
FPR3100 2.16.0 v2c/v3
FPR4100 2.16.0 v3
FPR9300 2.16.0 v2c/v3

Note: These MIBs require SNMP manager software supporting CISCO-UNIFIED-FIREWALL-MIB v3.1 or later.
