CVE-2025-65074: Wavestore VMS Server RCE Vulnerability

CVE-2025-65074 Overview

CVE-2025-65074 is a path traversal vulnerability [CWE-22] in Wavestore Video Management Software Server. The WaveView client permits users to execute a restricted set of predefined commands and scripts on the connected WaveStore Server. An attacker with high privileges can abuse path traversal in the showerr script to execute arbitrary operating system commands on the server. The flaw breaks the boundary between sanctioned scripts and unrestricted command execution, giving an authenticated adversary the ability to run code outside the intended command allow-list. Wavestore addressed the issue in version 6.44.44.

Critical Impact
An authenticated high-privilege attacker can execute arbitrary OS commands on the WaveStore Server, leading to full compromise of the video management infrastructure.

Affected Products

Wavestore Video Management Software Server (all versions prior to 6.44.44)
WaveView client connecting to vulnerable WaveStore Server instances
Deployments exposing the WaveView management interface to authenticated users

Technical Details for CVE-2025-65074

Vulnerability Analysis

The WaveView client communicates with the WaveStore Server to run a fixed list of administrative commands and helper scripts. One of these helpers, the showerr script, accepts a parameter that references a file or path to display. The server-side handler does not adequately validate or canonicalize this parameter before passing it to the underlying shell, allowing traversal sequences such as ../ to escape the intended directory.

Because the script ultimately invokes operating system commands, an attacker who controls the path argument can break out of the allow-listed command set and run arbitrary commands with the privileges of the WaveStore Server process. The vulnerability requires authentication with high privileges, which constrains opportunistic exploitation but does not protect against insider abuse, credential theft, or lateral movement scenarios where an attacker has already obtained an administrative account.

Root Cause

The root cause is missing input validation on the path argument supplied to the showerr script. The server trusts that arguments coming from the WaveView client conform to expected file locations and fails to apply canonical path resolution or an allow-list of permitted files. This classic CWE-22 weakness allows traversal sequences to redirect execution flow to attacker-influenced paths and commands.

Attack Vector

Exploitation is performed over the network against the WaveStore Server through the WaveView client protocol. The attacker authenticates with a high-privilege account, then issues a crafted request invoking showerr with a path argument containing traversal sequences and embedded command components. The server-side script processes the argument and executes attacker-controlled commands in the context of the WaveStore service. No user interaction is required beyond the attacker's own authenticated session.

No public proof-of-concept code is available at the time of publication. Technical details are described in the CERT Polska Security Advisory for CVE-2025-65074.

Detection Methods for CVE-2025-65074

Indicators of Compromise

Invocations of the showerr script containing ../, ..\, or URL-encoded traversal sequences in the path parameter
Unexpected child processes spawned by the WaveStore Server service, particularly shells, scripting interpreters, or system utilities
WaveView session activity from high-privilege accounts at unusual times or from unexpected source addresses
New or modified files written to system directories by the WaveStore Server process account

Detection Strategies

Inspect WaveStore Server logs for showerr requests with arguments that include path separators or traversal patterns
Correlate WaveView authentication events with subsequent process execution on the server host to identify command abuse
Apply endpoint detection rules that flag the WaveStore Server process spawning interpreters such as cmd.exe, powershell.exe, /bin/sh, or bash
Hunt for outbound network connections initiated by the WaveStore Server process to non-standard destinations

Monitoring Recommendations

Forward WaveStore Server application logs and host process telemetry to a centralized analytics platform for retention and correlation
Alert on any administrative WaveView command execution outside change-window hours
Track file integrity on directories accessible to the WaveStore Server service account
Monitor authentication logs for repeated high-privilege logons from new endpoints, which may indicate credential abuse preceding exploitation

How to Mitigate CVE-2025-65074

Immediate Actions Required

Upgrade Wavestore Video Management Software Server to version 6.44.44 or later on all affected systems
Inventory all WaveStore Server instances and confirm version compliance after patching
Rotate credentials for high-privilege WaveView accounts in case they were exposed prior to remediation
Restrict network reachability of the WaveStore Server management interface to trusted administrative networks only

Patch Information

Wavestore fixed CVE-2025-65074 in version 6.44.44 of the Video Management Software Server. Administrators should obtain the update directly from Wavestore and apply it following the vendor's upgrade procedure. Refer to the CERT Polska advisory and the Wavestore Video Management Software product page for vendor guidance.

Workarounds

Limit WaveView access to a minimal set of trusted administrators and enforce strong, unique passwords with multi-factor authentication where supported
Place the WaveStore Server behind network segmentation and firewall rules that block access from general user subnets
Audit and reduce the number of accounts holding high privileges within the WaveView application
Enable enhanced logging on the WaveStore Server host to capture command execution events for post-incident review

bash

# Example firewall restriction limiting WaveStore management access to an admin subnet
# Replace 10.10.50.0/24 with your administrative network and <WAVESTORE_PORT> with the configured port
iptables -A INPUT -p tcp --dport <WAVESTORE_PORT> -s 10.10.50.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport <WAVESTORE_PORT> -j DROP
