CVE-2025-8613 Overview
CVE-2025-8613 is a command injection vulnerability affecting Vacron Camera devices. The flaw resides in the webs.cgi endpoint, which fails to properly validate user-supplied input before passing it to a system call. Authenticated remote attackers can leverage this weakness to execute arbitrary operating system commands in the context of the root user. The Zero Day Initiative tracked this issue as ZDI-CAN-25892 and published advisory ZDI-25-805. The vulnerability maps to CWE-78, Improper Neutralization of Special Elements used in an OS Command.
Critical Impact
Successful exploitation grants attackers root-level code execution on the affected Vacron Camera, enabling full device takeover, surveillance feed manipulation, and lateral movement into connected networks.
Affected Products

Technical Details for CVE-2025-8613
Vulnerability Analysis
The vulnerability exists within the webs.cgi handler that processes ping-related requests on Vacron Camera devices. The CGI binary accepts a user-controlled string, typically a host or IP address, and concatenates it directly into a shell command invocation. Because the input is not sanitized or escaped, attackers can append shell metacharacters such as ;, |, or backticks to break out of the intended argument and execute arbitrary commands. The injected commands run with the privileges of the web service, which executes as root on these embedded Linux devices.
Exploitation requires valid credentials to reach the vulnerable endpoint. Once authenticated, an attacker issues a single crafted HTTP request to trigger command execution. The attack vector is network-based, and no user interaction is required beyond the initial authentication.
Root Cause
The root cause is missing input validation and unsafe construction of shell commands in the diagnostic ping functionality. The CGI handler passes attacker-controlled data into a system shell invocation without applying allow-listing, escaping, or parameterized execution. This pattern is the canonical example of CWE-78 OS command injection.
Attack Vector
The attacker authenticates to the camera's web interface, then submits an HTTP request to the webs.cgi ping endpoint. The host parameter contains shell metacharacters followed by an attacker-supplied command. The CGI process executes the appended command as root, returning output or enabling persistence through reverse shells, credential theft, or firmware modification. See the Zero Day Initiative Advisory ZDI-25-805 for the technical breakdown.
Detection Methods for CVE-2025-8613
Indicators of Compromise
- HTTP POST or GET requests to webs.cgi containing shell metacharacters (;, |, &, `, $()) in ping or diagnostic parameters
- Unexpected outbound connections initiated by the camera to attacker-controlled hosts
- New processes spawned by the web server parent process that are not part of normal camera operation
- Modifications to firmware configuration files or the appearance of unknown binaries in writable filesystem paths
Detection Strategies
- Inspect web access logs from Vacron Camera devices and upstream proxies for suspicious parameter values targeting webs.cgi
- Deploy network intrusion detection signatures that match command-injection payloads against the camera's HTTP traffic
- Baseline normal device behavior and alert on deviations such as new listening ports or outbound shell-like traffic
Monitoring Recommendations
- Forward camera logs and surrounding network telemetry into a centralized SIEM or data lake for correlation
- Monitor for repeated authentication attempts followed by webs.cgi requests, which may indicate brute force preceding exploitation
- Track DNS and NetFlow data from IoT VLANs to detect command-and-control activity originating from camera devices
How to Mitigate CVE-2025-8613
Immediate Actions Required
- Restrict network access to the camera management interface using firewall rules or VLAN segmentation; do not expose webs.cgi to the public internet
- Rotate all administrative credentials on Vacron Camera devices and enforce strong, unique passwords
- Audit existing devices for signs of compromise using the indicators listed above
- Apply vendor firmware updates referenced in the Zero Day Initiative Advisory ZDI-25-805 once available
Patch Information
At the time of NVD publication, no specific vendor patch URL is listed in the CVE record. Administrators should consult the Zero Day Initiative Advisory ZDI-25-805 and the Vacron support channels for firmware updates addressing the webs.cgi command injection.
Workarounds
- Place affected cameras on an isolated management network reachable only through a hardened jump host or VPN
- Disable remote administrative access where the diagnostic ping feature is not required
- Use an upstream web application firewall to block requests to webs.cgi containing shell metacharacters
- Decommission and replace devices that cannot be patched or adequately segmented
