CVE-2026-88277 Overview
CVE-2026-88277 is an OS command injection vulnerability [CWE-78] in the GeoVision GV-LPC2211 license plate capture camera running firmware V1.13. An authenticated Open Network Video Interface Forum (ONVIF) user can inject shell metacharacters through the ConsumerReference.Address parameter. The device processes the tainted input without proper sanitization and executes the supplied commands as root.
The flaw grants full operating system control over the camera to any account with valid ONVIF credentials. Successful exploitation compromises confidentiality, integrity, and availability of the device and any network segment it can reach.
Critical Impact
Authenticated attackers gain root-level command execution on the camera, enabling firmware tampering, credential theft, and lateral movement into video surveillance networks.
Affected Products
- GeoVision GV-LPC2211 license plate capture camera
- Firmware version V1.13
- Devices exposing the ONVIF service interface

Technical Details for CVE-2026-88277
Vulnerability Analysis
The GV-LPC2211 exposes an ONVIF web services endpoint that accepts SOAP requests for event subscription management. The ConsumerReference.Address field within these SOAP messages carries a URL identifying the notification consumer. Firmware V1.13 passes this value into a shell context without escaping metacharacters such as backticks, semicolons, or $() sequences.
An authenticated ONVIF user can embed arbitrary shell commands inside the address value. The camera then executes those commands with root privileges because the ONVIF service runs without privilege separation. This grants complete control over the embedded Linux environment.
Root Cause
The root cause is missing input validation and unsafe string concatenation into a shell invocation [CWE-78]. The affected code path treats the ConsumerReference.Address value as trusted data. No allow-list validation, quoting, or use of execve-style argument arrays prevents shell interpretation of the supplied characters.
Attack Vector
The attack is remotely reachable over the network wherever the ONVIF service is exposed. The attacker must first authenticate with any valid ONVIF account, including low-privileged operator or user roles. Once authenticated, the attacker sends a crafted SOAP subscription request containing shell payload characters inside ConsumerReference.Address.
The camera parses the request, invokes the vulnerable handler, and executes the payload as root. No user interaction is required, and exploitation completes within a single request.
No verified public proof-of-concept code is available in the CVE record. Refer to the Geovision Cyber Security Overview for vendor-published technical details.
Detection Methods for CVE-2026-88277
Indicators of Compromise
- ONVIF SOAP requests where the ConsumerReference.Address element contains shell metacharacters such as ;, |, &, backticks, or $(...) sequences
- Unexpected outbound connections from the camera to attacker-controlled infrastructure following event subscription calls
- New or modified files in writable firmware partitions on the camera, including additions to persistence locations such as /etc/init.d
- Anomalous root shell processes spawned by the ONVIF service binary
Detection Strategies
- Inspect HTTP and HTTPS traffic to the camera for SOAP payloads targeting the ONVIF event service and flag non-URL characters inside ConsumerReference.Address
- Baseline normal ONVIF client behavior and alert on subscription requests originating from unfamiliar source addresses
- Correlate authentication events on the camera with subsequent outbound network activity to identify post-exploitation callbacks
Monitoring Recommendations
- Forward camera syslog and network flow data to a centralized logging platform for retention and analysis
- Monitor the surveillance VLAN for unexpected east-west traffic that could indicate lateral movement from a compromised camera
- Alert on repeated ONVIF authentication attempts that precede event subscription calls, which may indicate credential brute forcing followed by exploitation
How to Mitigate CVE-2026-88277
Immediate Actions Required
- Restrict network access to the GV-LPC2211 ONVIF service to trusted management hosts using firewall or access control list rules
- Rotate all ONVIF account credentials on affected cameras and remove unused accounts
- Segment surveillance cameras onto an isolated VLAN with no direct route to sensitive internal networks
- Review camera logs for signs of prior exploitation, including unexpected process activity and outbound connections
Patch Information
Consult the Geovision Cyber Security Overview for vendor security advisories and firmware update availability for the GV-LPC2211. Apply any firmware release that supersedes V1.13 and addresses the ONVIF command injection.
Workarounds
- Disable the ONVIF service on the camera if it is not required for the deployment
- Block inbound access to the camera management interfaces from untrusted networks at the perimeter
- Enforce strong, unique passwords on all ONVIF accounts to raise the cost of the required authenticated foothold
# Example firewall restriction limiting ONVIF access to a management subnet
iptables -A INPUT -p tcp --dport 80 -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j DROP
iptables -A INPUT -p tcp --dport 443 -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
