CVE-2025-65075 Overview
CVE-2025-65075 is a path traversal vulnerability [CWE-22] in Wavestore Video Management Software Server. The WaveView client allows users to execute a restricted set of predefined commands and scripts on the connected WaveStore Server. An authenticated attacker with high privileges can abuse the alog script to traverse directories and read or delete arbitrary files with the permissions of the dvr user. The issue is resolved in version 6.44.44.
Critical Impact
An authenticated high-privileged attacker can read or delete arbitrary files on the WaveStore Server running as the dvr user, enabling potential tampering with surveillance data or disruption of video management operations.
Affected Products
- Wavestore Video Management Software Server versions prior to 6.44.44
- WaveView client connected to vulnerable WaveStore Server instances
- Deployments relying on the alog script for log retrieval

Technical Details for CVE-2025-65075
Vulnerability Analysis
The WaveView client exposes a controlled interface that invokes a predefined set of commands and scripts on the connected WaveStore Server. One of these, the alog script, accepts a file path argument but fails to validate or sanitize traversal sequences in the input.
An authenticated attacker with high privileges can supply crafted paths containing ../ sequences to escape the intended working directory. The script then operates on arbitrary files reachable by the dvr service account, including reads and deletions outside of the intended log directory.
Because the vulnerable logic executes server-side under the context of the dvr user, exploitation does not require local shell access. The attack is delivered through the client-server protocol over the network.
Root Cause
The root cause is insufficient input validation on file path arguments passed to the alog script. The script trusts caller-supplied paths without canonicalizing them or enforcing a boundary against the intended log directory, matching the pattern described by CWE-22: Improper Limitation of a Pathname to a Restricted Directory.
Attack Vector
Exploitation requires an authenticated session with high privileges on the WaveStore Server. The attacker invokes the alog script through the WaveView client interface and passes a path containing directory traversal sequences. The server-side script then reads or deletes the targeted file using the privileges of the dvr user account.

Detection Methods for CVE-2025-65075
Indicators of Compromise
- Invocations of the alog script containing ../ sequences or absolute paths pointing outside the standard log directory.
- Unexpected deletions or access events on files owned by or readable to the dvr user outside typical operational paths.
- WaveView client sessions from high-privileged accounts issuing non-standard command arguments.
Detection Strategies
- Audit WaveStore Server command logs for alog executions with suspicious path arguments and alert on traversal patterns.
- Correlate authenticated WaveView sessions with filesystem events generated by the dvr user to identify out-of-scope access.
- Compare installed WaveStore Server versions against 6.44.44 across the fleet to inventory exposure.
Monitoring Recommendations
- Enable verbose logging for script execution on the WaveStore Server and forward events to a central analytics platform.
- Monitor file integrity on surveillance evidence directories and configuration paths accessible to the dvr user.
- Alert on administrative WaveView logins from unexpected sources or outside maintenance windows.
How to Mitigate CVE-2025-65075
Immediate Actions Required
- Upgrade Wavestore Video Management Software Server to version 6.44.44 or later on all deployments.
- Review and reduce the number of accounts with high privileges on WaveView and WaveStore Server.
- Rotate credentials for high-privileged WaveView accounts and audit recent administrative activity.
Patch Information
The vendor fixed this issue in Wavestore Video Management Software Server version 6.44.44. See the CERT Polska Security Advisory and the Wavestore Video Management Software product page for release details and upgrade guidance.
Workarounds
- Restrict network access to the WaveStore Server management interface to trusted administrative networks only.
- Enforce least privilege for WaveView accounts and remove high-privileged roles from users who do not require them.
- Monitor and alert on alog script invocations until patching is complete across the environment.
