CVE-2025-64693
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 · uneditedSecurity Point (Windows) of MaLion and MaLionCloud contains a heap-based buffer overflow vulnerability in processing Content-Length. Receiving a specially crafted request from a remote unauthenticated attacker could lead to arbitrary code execution with SYSTEM privilege.
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 heap-based buffer overflow vulnerability exists in the Security Point component of MaLion and MaLionCloud for Windows when processing the Content-Length HTTP header. A remote unauthenticated attacker can send a specially crafted request with an oversized Content-Length value, causing memory corruption that leads to arbitrary code execution with SYSTEM privileges.

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.
-
Verify MaLion or MaLionCloud is installedCheck for the product in Windows installed programs (Add/Remove Programs), or look for installation directories such as C:\Program Files\MaLion or C:\Program Files\MaLionCloud, or check for running processes named MaLion.exe or MaLionCloud.exeAffected if The product is not installed or the specific vulnerable version is not present
-
Identify the installed versionLocate the main executable (MaLion.exe or MaLionCloud.exe), right-click and select Properties, or use command: dir "C:\Program Files\MaLion\*" /s /b or similar to find version info, then compare against any vendor-released version guidanceAffected if The installed version falls within the vulnerable range (if vendor publishes specific affected versions)
-
Confirm Security Point component is activeCheck if the Security Point web service is running. This is typically accessible via HTTP/HTTPS on a specific port (consult documentation or check running listeners with netstat -an | findstr LISTENING). The component processes HTTP requests including Content-Length headers.Affected if Security Point is enabled and listening for HTTP connections, making it network-accessible
-
Verify network exposure of the serviceReview firewall rules and network configuration to determine if the Security Point service port is exposed to untrusted networks. Use netsh advfirewall firewall show rule name=all or review inbound rules in Windows Firewall with Advanced Security.Affected if The Security Point HTTP service is accessible from untrusted network segments or the internet
If MaLion or MaLionCloud is installed with Security Point enabled and accessible over the network, and the version is unpatched, the environment is vulnerable to remote code execution via crafted Content-Length headers.

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 dataApply vendor-supplied patches immediately upon release. As an interim measure, restrict network access to the Security Point service to trusted IPs only, or temporarily disable the affected component if possible.
