CVE-2023-41720
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability exists on all versions of Ivanti Connect Secure below 22.6R2 where an attacker with a foothold on an Ivanti Connect Secure (ICS) appliance can escalate their privileges by exploiting a vulnerable installed application. This vulnerability allows the attacker to gain elevated execution privileges on the affected system.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceIvanti Connect Secure versions below 22.6R2 contain a privilege escalation vulnerability where an attacker with an existing foothold on the appliance can exploit a vulnerable installed application to gain elevated execution privileges on the affected system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Ivanti Connect Secure versionAccess the appliance admin interface or use the system status command to retrieve the installed version number. This is typically found in the system information or about section of the management console.Affected if The installed version is 22.1, 22.2, 22.3, 22.4, 22.5, or 22.6 (any version below 22.6R2).
-
Confirm the exact version stringVerify the full version string including any build numbers or release identifiers to distinguish between affected versions and the patched 22.6R2 release.Affected if The version string does not indicate version 22.6R2 or later.
-
Review user access logsExamine system and authentication logs for any unauthorized privilege escalation attempts or unexpected administrative actions that may indicate exploitation of this vulnerability.Affected if Evidence exists of privilege escalation from a low-privilege user to administrator-level access on the appliance.
A system is affected if Ivanti Connect Secure is running any version from 22.1 through 22.6, as these versions contain the vulnerable code that allows an authenticated attacker to escalate privileges.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade Ivanti Connect Secure to version 22.6R2 or later to remediate this vulnerability.
Ivanti Connect Secure 22.6R2 or later
- 1. Obtain the fixed version (22.6R2 or later) from Ivanti's official support portal or software distribution channel
- 2. Review the official Ivanti Connect Secure upgrade documentation for prerequisites and procedures
- 3. Create a complete backup of the current appliance configuration
- 4. Follow the standard Ivanti upgrade procedure to apply version 22.6R2 or later
- 5. After upgrade completion, verify the installed version matches the expected fixed release
- 6. Confirm the appliance is functioning normally and all services are operational
