Cisco mounted critical vulnerabilities throughout a number of of its merchandise this week, together with in its Industrial Community Director, Modeling Labs, ASR 5000 Collection Routers, and BroadWorks Community Server. The issues can result in administrative command injection, authentication bypass, distant privilege escalation and denial of service.

The Cisco Industrial Community Director (IND), a community monitoring and administration server for operational know-how (OT) networks, received patches for two vulnerabilities rated crucial and medium respectively. These have been mounted in model 1.11.3 of the software program.

The crucial flaw, CVE-2023-20036, is within the web-based person interface of Cisco IND and will enable authenticated distant attackers to execute arbitrary instructions on the underlying Home windows working system with administrative privileges (​​NT AUTHORITYSYSTEM). The vulnerability is the results of inadequate enter validation within the performance that permits customers to add System Packs.

The medium-risk flaw mounted in Cisco IND, CVE-2023-20039, is the results of insufficiently robust file permissions by default on the appliance information listing. A profitable exploit may enable an authenticated attacker to entry delicate data and information from this listing.

Cisco Modeling Labs flaw may enable for unauthorized distant entry

Cisco Modeling Labs, an on-premise community simulation instrument, has a critical vulnerability (CVE-2023-20154) that outcomes from processing sure messages from an exterior LDAP authentication server, which may enable an unauthenticated distant attacker to realize entry to the instrument’s internet interface with administrative privileges. This is able to give them entry to view and modify all simulations and user-created information.

The flaw impacts Modeling Labs for Training, Modeling Labs Enterprise and Modeling Labs – Not For Resale, however not Modeling Labs Private and Private Plus. It might probably solely be exploited if the exterior LDAP server is configured in a manner that it responds to look queries with a non-empty array of matching entries. The configuration of the LDAP server may be modified by an administrator to mitigate this flaw as a brief workaround, however prospects are suggested to improve Modeling Labs to model 2.5.1 to repair the vulnerability.

Privilege escalation attainable with Cisco StarOS flaw

The Cisco StarOS Software program which is used on ASR 5000 Collection Routers, but additionally on the Virtualized Packet Core – Distributed Occasion (VPC-DI) and Virtualized Packet Core – Single Occasion (VPC-SI) options, has a high-risk vulnerability (CVE-2023-20046) in its implementation of key-based SSH authentication.

Particularly, if an attacker sends an authentication request over SSH from an IP deal with configured because the supply for a high-privileged account, however as a substitute offers the SSH key for a low-privileged account, the system will authenticate them because the high-privileged account regardless that they did not present the right SSH key. This ends in privilege escalation and is the results of inadequate validation of the provided credentials.

As a workaround, directors may configure all person accounts which are accepted for SSH key-based authentication to make use of completely different IP addresses. Nevertheless, Cisco recommends upgrading to a set model of the software program.

Cisco BroadWorks vulnerability may result in denial of service

The Cisco BroadWorks Community Server obtained a patch for a high-risk vulnerability (CVE-2023-20125) in its TCP implementation that might result in a denial-of-service situation. The flaw outcomes from an absence of fee limiting for incoming TCP connections, permitting unauthenticated distant attackers to ship a excessive fee of TCP connections to the server and exhaust its system assets. Prospects are suggested to deploy the AP.ns.23.0.1075.ap385072.Linux-x86_64.zip or RI.2023.02 patches.

Cisco additionally patched a number of medium-risk flaws this week in its TelePresence Collaboration Endpoint and RoomOS, Cisco SD-WAN vManage Software program and the Cisco Packet Information Community Gateway. These can lead to arbitrary file write, arbitrary file deletion and IPsec ICMP denial of service.
