CVE-2026-42365 Overview
CVE-2026-42365 is a guessable session cookie vulnerability in the Web Interface of GeoVision GV-LPC2011 and GV-LPC2211 license plate capture cameras running firmware version 1.10. The flaw is classified under [CWE-341: Predictable from Observable State]. A remote unauthenticated attacker can issue a crafted series of HTTP requests to brute-force valid session cookies and bypass authentication on the device. Successful exploitation grants access to the administrative web interface without valid credentials.
Critical Impact
Remote attackers can bypass authentication on GeoVision GV-LPC2011/LPC2211 devices by guessing session cookies, exposing camera configuration and video data to unauthorized access.
Affected Products
- GeoVision GV-LPC2011 firmware version 1.10
- GeoVision GV-LPC2211 firmware version 1.10
- GeoVision GV-LPC2011 and GV-LPC2211 hardware platforms

Technical Details for CVE-2026-42365
Vulnerability Analysis
The vulnerability resides in the session management logic of the GeoVision LPC2011/LPC2211 Web Interface. The web application generates session cookies that lack sufficient entropy, making them predictable or guessable across a tractable keyspace. An attacker who can reach the device over the network can iterate through candidate cookie values until a valid authenticated session is matched.
Because the attack targets the cookie space rather than user credentials, it bypasses any password-strength controls present on the device. The CWE-341 classification reflects that the cookie state is derivable from observable inputs or limited randomness sources.
Root Cause
The root cause is the use of a weak or predictable algorithm for generating session identifiers in the embedded web server. Typical contributors include small cookie value ranges, sequential counters, low-resolution timestamps, or insufficient seeding of the random number generator at boot. The cookie space does not provide the cryptographic randomness required to resist online brute-force attempts.
Attack Vector
Exploitation occurs entirely over the network and requires no authentication or user interaction. An attacker sends a series of HTTP requests to the camera's web interface, each carrying a candidate session cookie value. When the device accepts a guessed cookie as a valid session, the attacker inherits the privileges of the corresponding logged-in user, including any administrative access. Devices exposed directly to the internet face the highest risk of automated exploitation.
No public proof-of-concept code or exploit module is available at the time of publication. Refer to the Talos Intelligence Vulnerability Reports for additional technical detail.
Detection Methods for CVE-2026-42365
Indicators of Compromise
- High volumes of HTTP requests to the camera web interface from a single source IP, each carrying different Cookie header values.
- Successful HTTP 200 responses to administrative endpoints without a preceding successful login request.
- Configuration changes, new user accounts, or firmware modifications on the camera that do not correspond to known administrator activity.
Detection Strategies
- Monitor web server and reverse proxy logs in front of GeoVision devices for rapid sequential requests with varying session cookies.
- Alert on authentication state transitions where a session is treated as valid without a corresponding login event.
- Correlate access patterns from camera management VLANs against expected administrator source addresses.
Monitoring Recommendations
- Capture network telemetry from segments hosting GV-LPC2011/LPC2211 cameras and inspect HTTP traffic for cookie brute-force signatures.
- Forward camera and gateway logs to a centralized SIEM for retention and rule-based alerting on anomalous request rates.
- Track outbound connections from camera devices to detect post-compromise command-and-control behavior.
How to Mitigate CVE-2026-42365
Immediate Actions Required
- Remove direct internet exposure of GV-LPC2011 and GV-LPC2211 management interfaces and place devices behind a firewall or VPN.
- Restrict access to the camera web interface to a dedicated management network and explicit administrator source IPs.
- Review device logs and configuration for unauthorized accounts, changed settings, or unexpected firmware versions.
Patch Information
Consult the GeoVision Cyber Security Overview for vendor advisories and firmware updates addressing CVE-2026-42365. Apply any updated firmware released for the GV-LPC2011 and GV-LPC2211 product lines as soon as it becomes available, and verify the post-update version is later than 1.10.
Workarounds
- Enforce network-layer access controls so only trusted hosts can reach the camera HTTP/HTTPS ports.
- Place the cameras on an isolated VLAN with no inbound connectivity from untrusted networks or the internet.
- Rate-limit and inspect HTTP traffic to the device using an upstream reverse proxy or web application firewall to disrupt cookie brute-force attempts.
- Rotate any administrator credentials and force re-authentication after applying network restrictions.
# Example: restrict access to GeoVision camera web interface using iptables
# Replace 10.0.10.0/24 with your management network
iptables -A FORWARD -p tcp -d 192.0.2.50 --dport 80 -s 10.0.10.0/24 -j ACCEPT
iptables -A FORWARD -p tcp -d 192.0.2.50 --dport 443 -s 10.0.10.0/24 -j ACCEPT
iptables -A FORWARD -p tcp -d 192.0.2.50 --dport 80 -j DROP
iptables -A FORWARD -p tcp -d 192.0.2.50 --dport 443 -j DROP
