In mjs_json.c in Cesanta MongooseOS mJS 1.26, a maliciously formed JSON string can trigger an off-by-one heap-based buffer overflow in mjs_json_parse, which can potentially lead to redirection of control flow. NOTE: the original reporter disputes the significance of this finding because "there isn’t very much of an opportunity to exploit this reliably for an information leak, so there isn’t any real security impact." En el archivo mjs_json.c en Cesanta MongooseOS mJS 1.26, una cadena JSON formada maliciosamente puede desencadenar un desbordamiento de búfer en la región heap de la memoria por un paso en la función mjs_json_parse, lo que potencialmente puede conllevar a un redireccionamiento del flujo de control • https://github.com/418sec/mjs/pull/2 https://github.com/cesanta/mjs/releases/tag/1.26 https://huntr.dev/bounties/1-other-mjs • CWE-193: Off-by-one Error CWE-787: Out-of-bounds Write •
