Introduction to asdm-openjre-7191-90.bin Software

This software package combines Cisco’s Adaptive Security Device Manager (ASDM) 7.19(1.90) with OpenJDK Runtime Environment 18, designed for secure firewall management on ASA 5500-X series appliances. The integrated solution addresses Java dependency challenges by bundling a verified JRE build that meets Cisco’s 2024 cryptographic standards.

Compatible with ​​ASA 5506-X, 5508-X, and 5516-X models​​, this release introduces mandatory digital signature verification for ASDM images when used with ASA OS 9.16(3.19)+. While Cisco’s release notes don’t specify an exact publication date, version sequencing indicates Q3 2024 availability alongside coordinated ASA platform updates.

Key Features and Improvements

  1. ​​Enhanced Cryptographic Compliance​​

    • Removes support for MD5/DES algorithms in SNMPv3 configurations, enforcing SHA-256/AES-256 encryption
    • Implements OpenJRE 18 with TLS 1.3 session resumption capabilities

  2. ​​Security Validation Enhancements​​

    • Mandatory Cisco digital signatures prevent unsigned ASDM image execution
    • Resolves CVE-2024-20359 (ASDM XML external entity injection vulnerability)

  3. ​​Platform Optimization​​

    • 40% reduction in Java heap memory consumption through modular JRE packaging
    • ARMv8 architecture exclusivity improves performance on 5508-X/5516-X hardware

  4. ​​Protocol Modernization​​

    • Exclusive SSHv2 support with ECDSA/EDDSA host key requirements
    • Discontinued DH groups 2/5/24 in SSL configurations

Compatibility and Requirements

Supported ASA Models Minimum ASA OS RAM/Flash Requirements
ASA 5506-X 9.16(3) 4GB/16GB
ASA 5508-X 9.14(1) 8GB/32GB
ASA 5516-X 9.12(4) 16GB/64GB

​​Critical Notes​​:

  • Incompatible with legacy Java Runtime Environments below JRE 8u351
  • Requires ASDM 7.18(1.152)+ for backward compatibility mode
  • Disabled Clientless SSL VPN support per Cisco’s deprecated features list

Software Distribution Channels

Licensed Cisco partners with Smart Net Total Care contracts can access the package through Cisco Software Center.
