CVE-2025-49080
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 · uneditedThere is a memory management vulnerability in Absolute Secure Access server versions 9.0 to 13.54. Attackers with network access to the server can cause a Denial of Service by sending a specially crafted sequence of packets to the server. The attack complexity is low, there are no attack requirements, privileges, or user interaction required. Loss of availability is high; there is no impact on confidentiality or integrity.
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 confidenceA memory management vulnerability exists in Absolute Secure Access server versions 9.0 through 13.54. Attackers with network access can send a specially crafted sequence of packets to trigger a memory handling error, causing the server to crash or become unresponsive. The attack requires no authentication or user interaction, resulting in complete loss of service availability.

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.
-
Confirm Absolute Secure Access server is deployedCheck running services or installed applications for 'Absolute Secure Access' or 'Absolute' server components. On Windows, review Programs and Features or services.msc. On Linux, check for rpm/deb packages or systemctl services containing 'absolute'.Affected if Absolute Secure Access server is installed in the environment
-
Identify installed versionRun the command to check the Absolute Secure Access server version. On Windows, right-click the application in Programs and Features and select Properties to view the Version field, or check the About section in the server admin console. On Linux, run: rpm -qa | grep -i absolute or dpkg -l | grep -i absolute.Affected if The installed version falls within the range >= 9.0 and <= 13.54
-
Verify server network accessibilityDetermine if the Absolute Secure Access server has an exposed network interface. Use netstat -an or ss -tlnp to identify listening ports and their bound addresses. Check firewall rules (Windows Firewall or iptables) to see if the server ports are open to untrusted networks.Affected if The server listens on interfaces accessible from untrusted networks (such as Internet-facing or DMZ segments)
-
Review server status for crash indicatorsCheck system logs (Windows Event Viewer under Application/System logs, or Linux /var/log/messages, /var/log/syslog) and Absolute Secure Access server logs for unexpected restarts, memory errors, or service failures occurring around the same time.Affected if The server has recently crashed, become unresponsive, or logged memory handling errors
You are affected if Absolute Secure Access server version 9.0 through 13.54 is installed and accessible over the network, since unauthenticated attackers can trigger the memory handling flaw to cause a denial of service.

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.
From vendor dataUpgrade Absolute Secure Access server to a version beyond 13.54, as indicated by the vendor. If immediate patching is not feasible, restrict network access to the server using firewalls or network segmentation to limit exposure to untrusted attackers.
