CVE-2026-88275 Overview
CVE-2026-88275 is a command injection vulnerability [CWE-78] in the GeoVision GV-LPC2211 license plate capture device running firmware V1.13. The device passes the administrator-supplied WPA-PSK value into a shell context when wireless configuration is applied. An authenticated administrator can embed shell metacharacters in the pre-shared key to execute arbitrary commands as root. The flaw affects the wireless configuration workflow of the embedded Linux platform.
Critical Impact
An authenticated administrator can achieve root-level command execution on the device, gaining full control of the camera and its network position.
Affected Products
- GeoVision GV-LPC2211 firmware V1.13
- GeoVision license plate capture appliances sharing the same wireless configuration handler
- Deployments exposing the administrative web interface to reachable networks

Technical Details for CVE-2026-88275
Vulnerability Analysis
The GV-LPC2211 exposes wireless configuration through its administrative interface. When an administrator applies a new wireless profile, the firmware constructs a shell command that includes the WPA-PSK value without sanitization. The device then executes this command as root to update the wireless supplicant configuration.
Because the PSK is interpolated directly into a shell string, characters such as `, $(), ;, and | are interpreted by the shell rather than treated as literal key material. The vulnerability is classified as OS Command Injection under [CWE-78]. Successful exploitation yields arbitrary code execution with root privileges on the underlying embedded Linux system.
The attacker precondition is administrator access to the device management interface. Post-exploitation impact includes persistent implants, network pivoting, credential theft from other stored configurations, and manipulation of captured license plate data.
Root Cause
The root cause is unsafe construction of a shell command using attacker-influenced input. The wireless configuration routine concatenates the WPA-PSK string into a command line passed to a shell interpreter. No input validation, escaping, or parameterized invocation is performed. See the GeoVision Cyber Security Resource for vendor guidance.
Attack Vector
Exploitation requires network access to the device management interface and valid administrator credentials. The attacker submits a wireless configuration change containing shell metacharacters embedded within the PSK field. When the device applies the configuration, the injected commands execute as root. The vulnerability chains effectively with credential reuse, default credentials left in production, or a session hijack against an authenticated administrator.
No verified exploit code is publicly available. See the GeoVision Cyber Security Resource for technical details.
Detection Methods for CVE-2026-88275
Indicators of Compromise
- Wireless configuration change events containing shell metacharacters such as `, $(, ;, |, or & in the PSK field
- Unexpected outbound connections from GV-LPC2211 devices to unfamiliar hosts following configuration changes
- Presence of new processes, cron entries, or startup scripts on the device that were not deployed by administrators
- Administrative logins from IP ranges inconsistent with normal operator locations
Detection Strategies
- Inspect HTTP request bodies to the device management interface for wireless configuration parameters containing shell syntax
- Correlate administrator authentication events with subsequent wireless configuration changes and outbound network activity
- Baseline expected DNS and outbound traffic from IoT camera VLANs and alert on deviations
Monitoring Recommendations
- Forward device syslog and administrative interface logs to a centralized analytics platform for retention and search
- Monitor management VLAN traffic for anomalous protocols originating from camera endpoints
- Alert on configuration change events outside of approved maintenance windows
How to Mitigate CVE-2026-88275
Immediate Actions Required
- Restrict access to the GV-LPC2211 administrative interface to a dedicated management network or jump host
- Rotate administrator credentials and remove any default or shared accounts on affected devices
- Audit recent wireless configuration changes for shell metacharacters in the PSK field
- Inventory all GeoVision GV-LPC2211 units and record firmware versions for patch tracking
Patch Information
Consult the GeoVision Cyber Security Resource for the vendor advisory and firmware updates addressing CVE-2026-88275. Apply the fixed firmware to all GV-LPC2211 devices running V1.13 as soon as it becomes available in your environment.
Workarounds
- Disable the wireless configuration feature and operate the device over wired Ethernet where feasible
- Place devices behind a network segment that blocks inbound access to the management interface from user and internet-facing networks
- Enforce strong, unique administrator credentials and require multi-factor authentication on the jump host used to reach device management
- Only apply wireless configuration changes from trusted administrative workstations under change control
# Configuration example: restrict management interface access with iptables on an upstream gateway
iptables -A FORWARD -s 10.10.20.0/24 -d 192.0.2.25 -p tcp --dport 443 -j ACCEPT
iptables -A FORWARD -d 192.0.2.25 -p tcp --dport 443 -j DROP
