CVE-2016-1335
HighSummary
The SSH implementation in Cisco StarOS before version 19.3.M0.62771 and 20.x before version 20.0.M0.62768 on ASR 5000 devices mishandles a multi-user public-key authentication configuration, allowing remote authenticated users to gain privileges by establishing a connection from an endpoint previously used for an administrator's connection.
Risk Assessment
The organization may be exposed to unauthorized access to systems, potentially leading to privilege escalation and security breaches.
Recommendation
It is recommended to update the system to the latest version of Cisco StarOS to mitigate this vulnerability and review the public key authentication configuration.
