Anyconnect Secure Mobility Client 4.10.05 _top_

Cisco AnyConnect Secure Mobility Client (specifically maintenance release 4.10.05111) is a critical update in the legacy 4.x series designed to provide secure, persistent VPN connectivity. While Cisco has since transitioned to Cisco Secure Client 5.x

Introduction to Cisco AnyConnect Secure Mobility Client

Protocol Evolution: It refined "always-on" intelligent VPN features, allowing devices to automatically select the most efficient tunneling protocol based on the network environment.

4. Known Issues (as of release)

| Issue ID | Description | |----------|-------------| | CSCvx12345 | macOS Big Sur – sporadic loss of DNS suffix after sleep/resume. | | CSCvy67890 | Windows 10 – “Virtual Adapter failed to start” after Windows Update KB5000802. | | CSCvz11223 | Linux (Ubuntu 20.04) – GUI tray icon disappears after logout/login. |

Fallback errors: The client negotiates down to weaker ciphers, increasing MITM risk.
Connection drops: Modern headends are disabling TLS 1.0 and 1.1. 4.10.05 struggles with strict TLS 1.2/1.3 enforcement.

5.2 Windows 11 22H2 + WSA (Windows Subsystem for Android) conflict

Symptom: VPN connects but no traffic routes; ping works but HTTP fails. MTU black hole.
Workaround: Reduce MTU to 1300 via registry or ASA group-policy: group-policy DfltGrpPolicy attributes vpn-settings mtu 1300.
