1 Critical and 3 High-Priority Security Vulnerabilities Among 26 Flaws Patched in Cisco Products during November 2024

Cisco, best known for its networking hardware and software lines, typically releases security advisories on a weekly basis. These advisories contain details of new vulnerabilities as well as instructions for obtaining product security updates. In this blog post, we summarise key details for all Cisco security fixes released in the last month, as well as highlight some of the most critical issues. The full list of advisories can be viewed in full via the Cisco Security Center, at: https://sec.cloudapps.cisco.com/security/center/publicationListing.x

Commentary

The Cisco security advisories issued in November 2024 include a high-priority fix for a critical flaw in Cisco’s Unified Industrial Wireless Software for Cisco Ultra-Reliable Wireless Backhaul (URWB) Access Points – exploit could allow an unauthenticated, remote attacker to perform command injection attacks with root privileges. There are several further ‘High’ priority fixes for vulnerabilities in the company’s Nexus Dashboard Fabric Controller (NDFC), Enterprise Chat and Email (ECE), and Secure Web Appliance product lines.

In addition, Cisco has published updates to existing security advisories for vulnerabilities in a raft of other products, most notably a set of eight total flaws in its Cisco Identity Services Engine (ISE). Other products receiving updates include IOS XR Software, Unified CCMP, Unified CM, and EPNM.

An advisory from CISA earlier in November also highlighted that the operators of the ‘AndroxGh0st’ malware/botnet have dusted off and targeted a decade-old Cross-Site Scripting (XSS) vulnerability in Cisco’s Adaptive Security Appliance (ASA) software (CVE-2014-2120). The exploitation of that vulnerability formed part of what is being called a ‘strategic expansion’ by the threat group, and highlighting that it’s not always just the latest bleeding-edge ‘0-day’ vulnerabilities that attackers are exploiting in the wild.

1 ‘Critical’ Severity Vulnerabilities

The list of ‘Critical’ severity vulnerabilities below are those that Cisco have rated as 9.0 or higher out of 10 under the “CVSS” (Common Vulnerability) scoring system – although this is at the discretion of Cisco. These vulnerabilities typically represent a critical risk to organisations – being both trivial for attackers to exploit, as well as having the potential to have significant impact (harm) if successfully exploited. Critical vulnerabilities are crucial to patch, and remediation is time sensitive – these types of vulnerabilities often feature in our “Known Exploited Vulnerabilities” (KEV) roundups as undergoing active exploitation if a threat group develops working exploit code and begins to actively target organisations. The vulnerabilities flagged as Critical severity in Cisco products this month includes:

3 Additional ‘High’ Severity Vulnerabilities

The list of ‘High’ severity vulnerabilities below are those that Cisco have rated between 7.0 and 8.9 out of 10 under the “CVSS” (Common Vulnerability) scoring system. High-severity vulnerabilities are still important to prioritise for remediation, but they are rated as a slightly lower risk than ‘critical’ vulnerabilities. This may be because they are either harder for attackers to exploit (such as requiring local rather than network access to exploit) or else considered to have a typically lower impact on systems and services if they were to be exploited. The vulnerabilities regarded as ‘High’ in Cisco products this month include:

How to Protect Your Organisation with AppCheck

All our vulnerability entries above contain links to official remediation guidance from Cisco in the form of their published Security Advisories, as well as details of mitigations or workarounds that can be performed if immediate patching is not possible. Cisco release free software updates and customers within service contracts are entitled to regular software updates containing security fixes via update channels.

To help customers determine their exposure to vulnerabilities in Cisco ASA, FMC, and FTD Software, Cisco also provides the Cisco Software Checker tool, available at https://sec.cloudapps.cisco.com/security/center/softwarechecker.x, which can be used to check if a specific software release is vulnerable to a given vulnerability.

We also recommend scanning your entire estate using the AppCheck vulnerability scanner regularly – both server systems and networking infrastructure, as well as end-user machines running desktop operating systems – in order to detect known vulnerabilities in your technical estate. Contact your account manager now to enquire about license options for our ‘internal scan hubs’ solution or, if not already a customer, book a demo or free trial at: info@appcheck-ng.com
