In short

Cisco IOS and related devices leak sensitive information from memory during IKEv1 security negotiations. An attacker can extract this data without authentication, potentially revealing passwords or encryption keys.

Technical detail

The IKEv1 implementation in affected Cisco platforms fails to properly sanitize memory buffers during Security Association negotiation, allowing unauthenticated remote attackers to read sensitive data through crafted SA requests. Pre-condition: IKEv1 service must be enabled; impact includes disclosure of credentials and cryptographic material.
