CVE-2025-57799: StreamVault Command Injection Vulnerability

CVE-2025-57799 Overview

CVE-2025-57799 is a command injection vulnerability [CWE-78] in StreamVault, a multi-platform video parsing and downloading tool. Authenticated attackers can modify system parameters to inject and execute arbitrary operating system commands on the underlying server. Successful exploitation grants attackers full server privileges through remote command execution.

All StreamVault versions prior to 250822 are affected. Systems using default or weak backend passwords face elevated risk because authentication is the primary barrier to exploitation. The maintainers released a fix in version 250822.

Critical Impact
Authenticated attackers can achieve full server compromise through OS command injection, leading to complete confidentiality, integrity, and availability loss.

Affected Products

StreamVault versions prior to 250822
StreamVault deployments retaining default backend credentials
StreamVault deployments using weak administrative passwords

Technical Details for CVE-2025-57799

Vulnerability Analysis

The vulnerability is an OS Command Injection flaw [CWE-78] in the authenticated administrative interface of StreamVault. After logging in, an attacker can supply crafted values in specific system parameter fields. The application passes these values into an operating system shell without sufficient validation or sanitization.

The attacker leverages shell metacharacters to append arbitrary commands to the underlying process invocation. Because the StreamVault backend typically runs with elevated service privileges, injected commands execute in that same security context. This turns a parameter update into a path to full server takeover.

Exploitation requires low-privilege authenticated access. However, StreamVault installations that keep default credentials or use weak passwords effectively remove that barrier. In such deployments, remote attackers can reach the vulnerable functionality with minimal effort.

Root Cause

The root cause is unsanitized user input flowing into a shell command execution routine. Configuration parameters accepted by the management interface are concatenated into commands without argument escaping or allowlist validation. The fix in version 250822 addresses this by sanitizing the affected parameters, as reflected in the GitHub Commit Update.

Attack Vector

The attack is delivered over the network against the StreamVault web management interface. The attacker authenticates using valid or guessed credentials, then submits a modified system parameter containing shell metacharacters such as ;, |, `, or $(). The backend evaluates the constructed command, executing the attacker-supplied payload alongside the intended operation.

Detection Methods for CVE-2025-57799

Indicators of Compromise

Unexpected child processes such as sh, bash, cmd.exe, powershell.exe, curl, or wget spawned by the StreamVault service account.
Outbound network connections from the StreamVault host to unfamiliar external IP addresses shortly after administrative logins.
Modifications to StreamVault system parameters containing shell metacharacters (;, |, &&, `, $()).
New cron jobs, scheduled tasks, or persistence artifacts created by the StreamVault process user.

Detection Strategies

Monitor process ancestry for the StreamVault runtime spawning shell interpreters or download utilities.
Inspect StreamVault application logs for administrative parameter changes containing shell control characters.
Correlate successful backend logins with subsequent process execution and outbound network activity.
Alert on writes to sensitive locations such as /etc/, /tmp/, web roots, or startup directories by the StreamVault service.

Monitoring Recommendations

Enable verbose audit logging for administrative actions in the StreamVault management console.
Forward host process telemetry and web access logs to a centralized analytics platform for correlation.
Track authentication events for the StreamVault backend, focusing on brute-force patterns and off-hours logins.
Baseline normal StreamVault child processes and alert on deviations.

How to Mitigate CVE-2025-57799

Immediate Actions Required

Upgrade StreamVault to version 250822 or later without delay.
Reset all backend administrative passwords and enforce strong, unique credentials.
Restrict network access to the StreamVault management interface using firewall rules or VPN gating.
Review StreamVault hosts for signs of prior exploitation, including unexpected files, users, and scheduled tasks.

Patch Information

The issue is patched in StreamVault version 250822. The upstream fix is available in the GitHub Commit Update, with additional context in the GitHub Security Advisory. Administrators should validate the running version after upgrade and confirm that parameter sanitization is active.

Workarounds

Place StreamVault behind an authenticated reverse proxy that blocks shell metacharacters in parameter values.
Restrict access to the administrative interface to trusted management networks only.
Run the StreamVault service under a dedicated low-privilege account with no shell and minimal filesystem permissions.
Disable or remove unused administrator accounts and rotate credentials for any account that used default passwords.

bash

# Configuration example: restrict access and run as low-privilege user
# 1. Firewall: allow admin UI only from a trusted management subnet
iptables -A INPUT -p tcp --dport 8080 -s 10.10.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP

# 2. Run StreamVault as a dedicated non-privileged user with no login shell
useradd --system --shell /usr/sbin/nologin streamvault
chown -R streamvault:streamvault /opt/streamvault

# 3. Verify installed version is patched
grep -i version /opt/streamvault/VERSION   # expect: 250822 or later
