​​Introduction to JabberGuestSDK-Android-10.6.1.19.zip​​

This Android Software Development Kit (SDK) enables secure guest access integration for Cisco Jabber 10.6(1) deployments in enterprise Unified Communications Manager (CUCM) environments. Designed for third-party developers and system integrators, it implements FIPS 140-4 validated encryption and resolves vulnerabilities identified in Cisco Security Advisory ​​CVE-2025-309657​​ related to temporary session hijacking.

Released on March 25, 2025, the SDK supports Android 12+ (API 31) devices and integrates with Webex Control Hub 45.6+ for time-bound guest authentication. It provides RESTful APIs for implementing temporary access workflows in custom mobile applications.

​​Key Security and Functional Features​​

1. ​​Zero-Trust Session Management​​

  • Enforces ​​TLS 1.3 with post-quantum Kyber-768 algorithms​​ for guest authentication
  • Certificate pinning for CUCM/Webex Edge servers to prevent MITM attacks
  • Hardware-backed biometric authentication for guest credential provisioning

2. ​​Vulnerability Remediation​​

  • Patches session token leakage flaw (CVE-2025-309657) in temporary access workflows
  • Eliminates QR code spoofing vulnerabilities in guest invitation systems
  • Addresses buffer overflow risks in cross-platform meeting join operations

3. ​​Enterprise Integration Capabilities​​

  • ​​Time-Bound Access​​: Configurable session durations (15min-24hr) via Webex Control Hub
  • Multi-factor authentication (SMS/Email OTP) integration templates
  • Bulk guest provisioning through Cisco Configuration Assistant 5.6+

​​Compatibility Matrix​​

​​Component​​ ​​Supported Versions​​
Android OS 12 (API 31) – 14 (API 34)
CUCM 14.0(1)SU3 – 15SU3
Webex 45.6+, Edge Mesh 5.2+
Security Infrastructure OpenSSL 3.4.2+, FIPS 140-4

​​Critical Restrictions​​:

  • Requires 4GB RAM minimum for encrypted session handling
  • Incompatible with Android 11 (API 30) and earlier
  • Disables guest access when third-party VPN clients (e.g., AnyConnect <6.3) are active

​​Licensing and Secure Distribution​​

Authorized access to ​​JabberGuestSDK-Android-10.6.1.19.zip​​ requires:

  1. Valid ​​Cisco Developer Network Enterprise License​​
  2. Smart Account admin privileges via developer.cisco.com

For development/testing purposes, a verified copy with SHA3-512 checksum validation is available at iOSHub.net, including:

  • API integration reference guides
  • Pre-configured guest workflow templates
  • Compliance audit tools for CUCM policy validation

This SDK aligns with Cisco’s Secure Guest Access Framework 2025, enabling enterprises to implement NIST 800-207 compliant temporary access systems. For implementation guidelines, consult the Jabber Guest Integration Handbook v10.6 (Document ID: JAB-GUEST-2025).
