CVE-2025-10225
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 Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) in the OpenSSL-based session module in AxxonSoft Axxon One (C-Werk) 2.0.6 and earlier on Windows allows a remote attacker under high load conditions to cause application crashes or unpredictable behavior via triggering memory reallocation errors when handling expired session keys.
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 buffer handling vulnerability exists in the OpenSSL-based session module of AxxonSoft Axxon One (C-Werk) 2.0.6 and earlier on Windows. Under high load conditions, a remote attacker can trigger memory reallocation errors when the system processes expired session keys, leading to memory corruption, application crashes, or unpredictable behavior.

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 installed Axxon One versionOpen Windows Control Panel > Programs and Features, or check the installation directory for a version file. The executable is typically named 'C-Werk.exe' or similar. Right-click the executable, select Properties, and inspect the Version tab.Affected if The installed version is 2.0.6 or any version lower than 2.0.6 on Windows.
-
Confirm operating system platformVerify that the Axxon One server is running on Windows. This vulnerability only affects the Windows implementation of the session module.Affected if The system is running any Windows version with Axxon One <= 2.0.6 installed.
-
Determine if session module is activeInspect the Axxon One configuration files (typically in the installation directory under 'config' or 'settings' folders) for session-related settings. Look for configurations referencing OpenSSL, session keys, or authentication modules.Affected if The session module using OpenSSL is enabled in the configuration.
-
Review application event logs for session errorsOpen Windows Event Viewer > Application Logs. Search for events from Axxon One or C-Werk around the time of crashes. Look for entries mentioning memory allocation failures, OpenSSL errors, or session key processing failures.Affected if Event logs show recurring errors related to session handling, memory corruption, or unexpected process terminations.
-
Check for high-load session activityMonitor network connections to the Axxon One server port (default HTTP ports 80/443 or custom ports). Use 'netstat -an' or the Windows Resource Monitor to observe connection patterns and check for unusual spikes in session initialization traffic.Affected if The system experiences high volumes of session-related requests and shows instability or crashes correlated with this load.
A system is affected if it runs Axxon One version 2.0.6 or earlier on Windows, has the OpenSSL-based session module enabled, and exhibits crash behavior or memory errors during high session load.

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 the vendor patch or upgrade to Axxon One version later than 2.0.6. If no patch is available, consider restricting network access to the affected system and monitoring for signs of session-based DoS attacks.
