Loading vulnerability…
CVE-2026-39047 is a buffer overflow vulnerability in the EPSON L14150 printer firmware identified as FL27PB. The flaw is exposed through the device's RAW Printing Service, also referred to as JetDirect, listening on TCP port 9100. A remote attacker can trigger the vulnerability by sending crafted network data to the printing service, causing memory corruption that can lead to arbitrary code execution on the target device.

Repository contains a small standalone Python exploit PoC for alleged CVE-2026-39047 against Epson printers using the RAW printing service on TCP/9100, plus a mock vulnerable server for safe testing and a README describing usage. The main exploit file is poc.py, which implements a custom transport frame builder (PRT2 + version + payload length), seed derivation, payload obfuscation (zlib compression, XOR masking, Base64), and multiple payload generation techniques including cyclic, format-string-like, random, and sled-style content. It also includes staged post-exploitation command generation that creates runtime artifacts under /tmp and optional persistence simulation under /etc/rc.d. The CLI supports passive mode, fuzzing, hijack/staging objectives, callback metadata, capability selection, dry-run, technique selection, and inter-payload delay. The mock_printer.py file is a simple threaded TCP server listening on 0.0.0.0:9100 that parses the same framed protocol and exits when payloads exceed 1024 bytes, simulating a crash. Overall, this is an operational network exploit PoC/framework rather than a detector: it can actively send crafted traffic to a target printer service and includes basic post-exploitation simulation logic.
