Avulnerability in the client update process of Cisco AnyConnect Secure Mobility Client Software for Windows and Cisco Secure Client Software for Windows could allow a low-privileged, authenticated, local attacker to elevate privileges to those of SYSTEM. The client update process is executed after a successful VPN connection is established.
This vulnerability exists because improper permissions are assigned to a temporary directory that is created during the update process. An attacker could exploit this vulnerability by abusing a specific function of the Windows installer process. A successful exploit could allow the attacker to execute code with SYSTEM privileges.
Cisco has released free software updates that address the vulnerability described in this advisory. Customers with service contracts that entitle them to regular software updates should obtain security fixes through their usual update channels.
Customers may only install and expect support for software versions and feature sets for which they have purchased a license. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license:
-user-license-agreement.html
Additionally, customers may only download software for which they have a valid license, procured from Cisco directly, or through a Cisco authorized reseller or partner. In most cases this will be a maintenance upgrade to software that was previously purchased. Free security software updates do not entitle customers to a new software license, additional software feature sets, or major revision upgrades.
The Cisco Support and Downloads page on Cisco.com provides information about licensing and downloads. This page can also display customer device support coverage for customers who use the My Devices tool.
When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page, to determine exposure and a complete upgrade solution.
In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.
Customers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco TAC: -cisco-worldwide-contacts.html
In the following tables, the left column lists Cisco software releases. The right column indicates whether a release is affected by the vulnerability that is described in this advisory and the first release that includes the fix for this vulnerability. Customers are advised to upgrade to an appropriate fixed software release as indicated in this section.
To learn about Cisco security vulnerability disclosure policies and publications, see the Security Vulnerability Policy. This document also contains instructions for obtaining fixed software and receiving security vulnerability information from Cisco.

SSL-VPN: This has no standard/RFC, so as a rule of thumb you should always assume no compatibility between vendors, unless explicitly confirmed by either side. (And as far as I know, this is the case here too)
IPsec: IPsec is mostly standardized, and there is even a "Dialup - Cisco IPsec Client" wizard template in FortiOS GUI. However, the last time I've heard about this, this teplate supposedly only works with some old/outdated Anyconnect versions, and new/current Anyconnect clients are reportedly incompatible with general third-party solutions due to some vendor-specific proprietary attributes used by Anyconnect and ASA.
I'm using the ASA-5515 in my old system, and as upgrade I'm switching to the Fortigate 200F. Regarding the budged, ZTNA will be implemented in 2024, so that's why I will use the anyconnect solution for the moment.
The Fortinet Security Fabric brings together the concepts of convergence and consolidation to provide comprehensive cybersecurity protection for all users, devices, and applications and across all network edges.
Keep getting this message when trying to re-install Cisco VPN - "anyconnect secure mobility client cannot be installed on this disk. Version 3.1.02026 of the cisco anyconnect secure mobility client is already installed." Moved and deleted and when I search I only find the download or emails with information on the subject.
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
Tried again with reboots (same way I did before) and it worked loading the web based one. Talked with our VPN guru here also (has a MAC at home) and went through the process with him and he did the same thing I did. Well, it worked for him.
Now, with Secure Client, you gain improved secure remote access, a suite of modular security services, and a path for enabling Zero Trust Network Access (ZTNA) across the distributed network. The newest capability is in Secure Endpoint as a new module within the unified endpoint agent framework. Now you can harness Endpoint Detection & Response (EDR) from within Secure Client. You no longer need to deploy and manage Secure Client and Secure Endpoint as separate agents, making management more effortless on the backend.
Within Device Insights, Secure Client lets you deploy, update, and manage your agents from a new cloud management system inside SecureX. If you choose to use cloud management, Secure Client policy and deployment configuration are done in the Insights section of Cisco SecureX. Powerful visibility capabilities in SecureX Device Insights show which endpoints have Secure Client installed in addition to what module versions and profiles they are using.
The emphasis on interoperability of endpoint security agents helps provide the much-needed visibility and simplification across multiple Cisco security solutions while simultaneously reducing the complexity of managing multiple endpoints and agents. Application and data visibility is one of the top ways Secure Client can be an important part of an effective security resilience strategy.
We are not sure what specific issue you are referring to. The last round of issues were resolved by a macOS update and we also put in a workaround from our side. Please reach out to
ac-mobile...@cisco.com if you need help with something still not functioning properly with current Secure Client and macOS versions.
I like that the Secure Clients are converging, but multiple UI versions, 4.1 for AnyConnect and 5.0 for SecureEndpoint are not working together well for the user. I can find no supporting information on this.
We're using Cisco Anyconnect version 3.1 and are having issues using the syslog user-id receiver in panos 6.1.3. The default syslog profile for cisco anyconnect 1.0 and the regex entriy doesn't correctly interpet the correct user id dhcp assigned IP address. Need help ASAP creating new or correct regex.
I've been on the phone with support for the last few days and I am having the EXACT same issue. Same panos and anyconnect version. I think it has something to do with the regex setting looking at the first ip which should be public but I'm not sure. I wish I knew regex better. Someone PLEASE HELP!
As root, first unzip and untar the file, then run the vpn_install shell script. [Note the file name and directory name will change as the version changes. The example below was from version 4.3.05017.]
Then install the Ubuntu Network Manager plugins (note, even with this package Ubuntu 16 does not support the GUI interface: see -more-anyconnect-compatible-vpn-transport-in-ubuntu-16-04 for more information):
