Buffer Overflow vulnerability in arendst Tasmota v.15.3.0.3 and before allows a remote attacker to execute arbitrary code via the xdrv_10_scripter.ino, fetch_jpg(), jpg_task.boundary[40], strcpy() function.
AnalysisAI
Remote code execution in Tasmota firmware (v15.3.0.3 and all earlier releases) stems from an unbounded strcpy() into the fixed 40-byte jpg_task.boundary[40] buffer inside fetch_jpg() in the Scripter driver (xdrv_10_scripter.ino). A network attacker able to reach the device and trigger this code path can overflow the buffer and, per the vendor description, execute arbitrary code on the ESP-based device. …
