    Hardcoded SSH Key in Cisco Policy Suite Lets Remote Hackers Gain Root Access


    SSH Key in Cisco Policy Suite

    Cisco Techniques has launched security updates to handle vulnerabilities in a number of Cisco merchandise that may very well be exploited by an attacker to log in as a root consumer and take management of weak methods.

    Tracked as CVE-2021-40119, the vulnerability has been rated 9.8 in severity out of a most of 10 on the CVSS scoring system and stems from a weak spot within the SSH authentication mechanism of Cisco Coverage Suite.

    “An attacker might exploit this vulnerability by connecting to an affected system by means of SSH,” the networking main defined in an advisory, including “A profitable exploit might enable the attacker to log in to an affected system as the foundation consumer.” Cisco stated the bug was found throughout inside safety testing.

    Automatic GitHub Backups

    Cisco Coverage Suite Releases 21.2.0 and later may even mechanically create new SSH keys throughout set up, whereas requiring a guide course of to alter the default SSH keys for gadgets being upgraded from 21.1.0.

    Additionally addressed by Cisco are multiple critical vulnerabilities affecting web-based administration interface of the Cisco Catalyst Passive Optical Community (PON) Sequence Switches Optical Community Terminal (ONT) that would allow an unauthenticated, distant attacker to log in utilizing an inadvertent debugging account current within the system and take over management, carry out a command injection, and modify the configuration of the system.

    The vulnerabilities influence the next gadgets —

    • Catalyst PON Swap CGP-ONT-1P
    • Catalyst PON Swap CGP-ONT-4P
    • Catalyst PON Swap CGP-ONT-4PV
    • Catalyst PON Swap CGP-ONT-4PVC
    • Catalyst PON Swap CGP-ONT-4TVCW

    Marco Wiorek of Hotzone GmbH has been credited with reporting the three vulnerabilities which have been assigned the identifiers CVE-2021-34795 (CVSS rating: 10.0), CVE-2021-40113 (CVSS rating: 10.0), and CVE-2021-40112 (CVSS rating: 8.6).

    Prevent Data Breaches

    Lastly, Cisco has remediated two extra high-severity flaws in Cisco Small Enterprise Sequence Switches and Cisco AsyncOS that would enable unauthenticated, distant adversaries to realize unauthorized entry to the web-based administration interface of the switches and perform a denial of service (DoS) assault —

    • CVE-2021-34739 (CVSS rating: 8.1) – Cisco Small Enterprise Sequence Switches session credentials replay vulnerability
    • CVE-2021-34741 (CVSS rating: 7.5) – Cisco E-mail Safety Equipment (ESA) denial of service vulnerability
