CWE-306Published: May 19, 2026· Updated: May 21, 2026
Official Description
In ScadaBR version 1.2.0, a Missing Authentication for Critical Function vulnerability could allow an unauthenticated attacker to send a HTTP GET requests to the SCADA system and inject arbitrary sensor readings.
Risk Analysis
This critical vulnerability in ScadaBR 1.2.0 allows an unauthenticated attacker to inject arbitrary sensor readings into the SCADA system. With a CVSS score of 9.1, this flaw poses a high risk to data integrity and system reliability.
No public exploit is currently known for this vulnerability. Its remote exploitability and low attack complexity mean it could be easily abused if an exploit emerges.
Upgrade ScadaBR to a patched version if available. Implement robust authentication mechanisms for critical functions and restrict network access to the SCADA system.
Technical Analysis
CVE-2026-8602 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.1.
