CVE-2024-26290
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 · uneditedImproper Input Validation vulnerability in Avid Avid NEXIS E-series on Linux, Avid Avid NEXIS F-series on Linux, Avid Avid NEXIS PRO+ on Linux, Avid System Director Appliance (SDA+) on Linux allows code execution on underlying operating system with root permissions.This issue affects Avid NEXIS E-series: before 2024.6.0; Avid NEXIS F-series: before 2024.6.0; Avid NEXIS PRO+: before 2024.6.0; System Director Appliance (SDA+): before 2024.6.0.
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 · high confidenceImproper input validation in Avid NEXIS E-series, F-series, PRO+, and System Director Appliance (SDA+) storage systems running on Linux allows authenticated or unauthenticated attackers to execute arbitrary code with root privileges. The vulnerability stems from insufficient validation of user-supplied input before use in system operations.

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.
-
Identify if the system is an Avid NEXIS applianceCheck for Avid NEXIS-specific processes, services, or directories. Look for processes named 'avidnexis', 'nexis', or 'sda' (for System Director Appliance), or check for /opt/avid/nexis or similar installation directories.Affected if The system runs Avid NEXIS E-series, F-series, PRO+, or SDA+ software on Linux
-
Determine the installed Avid NEXIS versionCheck the installed version by examining version files in the installation directory (commonly /opt/avid/nexis/version or similar), or run 'dpkg -l | grep -i avid' or 'rpm -qa | grep -i avid' if using package management.Affected if The installed version is older than 2024.6.0 (the fixed release)
-
Verify if the management interface is accessibleCheck if the web-based management interface or command-line management ports are open and listening. Look for services on typical management ports or check running services with 'netstat -tulpn' or 'ss -tulpn'.Affected if Management interfaces are exposed without network segmentation
-
Check for signs of privilege escalationReview system logs (especially /var/log/ and /opt/avid/nexis/logs/) for unexpected commands run as root, unusual authentication events, or privilege escalation attempts from the avidx or nexis service accounts.Affected if Logs show authenticated commands executed as root that were not initiated by legitimate administrators
-
Confirm the Linux operating system baseVerify the underlying OS is Linux by running 'uname -a' or checking /etc/os-release. Avid NEXIS runs on a Linux-based appliance OS.Affected if The system runs a Linux-based Avid NEXIS appliance firmware
A user is affected if they are running Avid NEXIS E-series, F-series, PRO+, or SDA+ on Linux with a version older than 2024.6.0 and the management interface is accessible to authenticated attackers.

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 · scopedApply Avid version 2024.6.0 or later to all affected NEXIS E-series, F-series, PRO+, and SDA+ appliances. This is a critical update requiring careful staging and rollback planning due to the root-level code execution risk.
2024.6.0
- 1. Identify the specific Avid NEXIS product model (E-series, F-series, PRO+, or SDA+) in your environment
- 2. Access the Avid NEXIS management interface or use the command line to verify the current software version
- 3. Confirm the current version is before 2024.6.0 to determine if the system is vulnerable
- 4. Consult the official Avid knowledge base (kb.avid.com) for the specific upgrade procedure for your product model
- 5. Download the 2024.6.0 or later update package from Avid's official support portal
- 6. Follow Avid's documented upgrade procedure, ensuring proper backup of configuration data
- 7. After upgrading, verify the new version is 2024.6.0 or later
- 8. Validate that the vulnerability is resolved by checking the system operates normally
