GV-LPC2011/LPC2211: Predictable from Observable State
CVE-2026-42365 is a high-severity predictable from observable state vulnerability in GV-LPC2011/LPC2211 from GeoVision, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected GV-LPC2011/LPC2211 versions: 1.10. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.34% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of GV-LPC2011/LPC2211 you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on geovision.com.tw for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
A guessable session cookie vulnerability exists in the Web Interface functionality of GeoVision LPC2011/LPC2211 1.10. A specially crafted series of HTTP requests can lead to an authentication bypas. An attacker can bruteforce session cookies to trigger this vulnerability.

The underlying weakness: Predictable from Observable State
A number or object is predictable based on observations that the attacker can make about the state of the system or network, such as time, process ID, etc.
How developers prevent this class of flaw
- Increase the entropy used to seed a PRNG.
- Use products or modules that conform to FIPS 140-2 to avoid obvious entropy problems. Consult FIPS 140-2 Annex C (Approved Random Number Generators).
- Use a PRNG that periodically re-seeds itself using input from high-quality sources, such as hardware devices with high entropy. However, do not re-seed too frequently, or else the entropy source might block.
