Vulnerability Spotlight: Code execution vulnerabilities in Prusa Slicer
Summary: Cisco Talos discovered two out-of-bounds write vulnerabilities in Prusa Research's PrusaSlicer, an open-source 3-D printer slicing program forked from Slic3r, in the Obj.cpp load_obj() and Objparser::objparse() functions. Specially crafted OBJ files can trigger the flaws to gain code execution on the victim machine, affecting PrusaSlicer 2.2.0 and Master commit 4b040b856, with Snort rules 56727 and 56728 released to detect exploitation attempts.
Bottom line: A malicious OBJ file is enough to execute code on a machine running PrusaSlicer 2.2.0, so any shop that opens third-party 3-D models is exposed until the update is applied.
