The version "1.25" is archaic. It dates back to early Cisco IOS (Internetwork Operating System) implementations from the early-to-mid 2000s. While modern Cisco devices run much newer SSH implementations, seeing this specific version string in 2023/2024 is an immediate red flag. It suggests the device is running an operating system that has not been updated in potentially two decades. Addressing the risks associated with devices displaying the

The Cisco-1.25 engine variant often relies on legacy default cryptographic configurations. It defaults to vulnerable Cipher Block Chaining (CBC) modes or older algorithms like Triple DES (3DES) and Blowfish. These algorithms are highly susceptible to modern traffic decryption techniques, sniffing, and Man-in-the-Middle (MitM) injection attacks.
