**Name of the Vulnerable Software and Affected Versions** Paramiko versions prior to 1.17.6 Paramiko versions 1.18.x prior to 1.18.5 Paramiko versions 2.0.x prior to 2.0.8 Paramiko versions 2.1.x prior to 2.1.5 Paramiko versions 2.2.x prior to 2.2.3 Paramiko versions 2.3.x prior to 2.3.2 Paramiko versions 2.4.x prior to 2.4.1 **Description** The issue is related to the `transport.py` component of the Paramiko library, which has weaknesses in its authentication procedure. This allows a remote attacker to access confidential data, compromise its integrity, and cause a denial of service. The vulnerability can be exploited by a customized SSH client that skips the authentication step, as demonstrated by the `channel-open` request. **Recommendations** For Paramiko versions prior to 1.17.6, update to version 1.17.6 or later. For Paramiko versions 1.18.x prior to 1.18.5, update to version 1.18.5 or later. For Paramiko versions 2.0.x prior to 2.0.8, update to version 2.0.8 or later. For Paramiko versions 2.1.x prior to 2.1.5, update to version 2.1.5 or later. For Paramiko versions 2.2.x prior to 2.2.3, update to version 2.2.3 or later. For Paramiko versions 2.3.x prior to 2.3.2, update to version 2.3.2 or later. For Paramiko versions 2.4.x prior to 2.4.1, update to version 2.4.1 or later. As a temporary workaround, consider restricting access to the `transport.py` component until a patch is available.

**Name of the Vulnerable Software and Affected Versions** Cisco Prime Collaboration Provisioning Software Releases prior to 12.1 **Description** A vulnerability in the web interface of Cisco Prime Collaboration Provisioning allows an unauthenticated, remote attacker to bypass authentication and perform command injection with root privileges. This is due to missing security constraints in certain HTTP request methods, which could allow access to files via the web interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to the targeted application. **Recommendations** For Cisco Prime Collaboration Provisioning Software Releases prior to 12.1, update to a version 12.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the web interface to minimize the risk of exploitation.
