This is not theoretical: a version of the pico 300alpha2 exploit was used in a live-fire red team exercise against a European energy provider in late 2025, leading to full operational control of 14 substation controllers.
In early 2025, a team of researchers from the Industrial Exploit Lab at Securitas Global disclosed three distinct but interlocking vulnerabilities affecting firmware versions 3.0.12 to 3.2.0 of the Pico 300alpha2. They collectively dubbed the attack chain , though the security community quickly began referring to the primary remote code execution (RCE) vector as the pico 300alpha2 exploit .
A directory traversal flaw in index.php that could allow unauthorized file access. pico 300alpha2 exploit
There is a known vulnerability regarding , which affects ESP32 v3.0 (often referred to as "rev 300" in technical logs).
Because this exploit can occur at the bootloader level, it allows for the installation of rootkits that persist even after a factory reset. This is not theoretical: a version of the
When processed by the vulnerable pico-static-server , this translates to ../../etc/passwd , allowing the server to look up directories above the intended web root, ultimately disclosing the content of the etc/passwd file, which contains system user information. Consequences of the 3.0.0-alpha.2 Vulnerability
