Python pakettis Js2Py, mis laaditi eelmisel kuul alla 1,2 miljonit korda, avastati haavatavus (CVE-2024-28397), mis v\u00f5imaldab k\u00f5rvale hiilida liiva kastist isolatsioonist ja k\u00e4ivitada s\u00fcsteemis koodi spetsiaalselt vormindatud JavaScript andmete t\u00f6\u00f6tlemisel. Haavatavust saab kasutada r\u00fcnnakute jaoks programmide vastu, mis kasutavad Js2Py JavaScript koodi t\u00e4itmiseks. Parandus on praegu saadaval ainult patachina. R\u00fcnnakuv\u00f5imekuse kontrollimiseks on loodud eksploiti protot\u00fc\u00fcp.<\/p>\n

Js2Py pakett rakendab JavaScripti t\u00f5lkijat ja interpreteerijat, mis v\u00f5imaldab t\u00e4ita JavaScripti koodi isoleeritud. virtuaalses masinas<\/a> v\u00f5i t\u00f5lkida JavaScripti Pythonisse. Projekt on t\u00e4ielikult kirjutatud Pythonis ja ei kasuta kolmanda osapoole JavaScripti mootoreid. Praktikas kasutatakse raamatukogu erinevates veebindeksijates, t\u00f5ukimise s\u00fcsteemides ja veebilehtede anal\u00fcsaatorites, mis toetavad JavaScriptiga genereeritud sisu t\u00f6\u00f6tlemist. <\/p>\n

Rakendustest, mida haavatavus m\u00f5jutab, mainitakse Lightnovel Crawlerit (t\u00f6\u00f6riist raamatute allalaadimiseks veebiteenustest ja nende salvestamiseks erinevates formaatides offline-lugemiseks), cloudscraperit (automaatne kaitsen\u00f5uete \u00fcmbers\u00f5idu t\u00f6\u00f6riist, mida kasutatakse CDN Cloudflare'is) ja pyLoadi (allalaadimise haldaja, mis toetab JavaScriptiga genereeritud lehtede t\u00f6\u00f6tlemist). Neis rakendustes spetsiaalselt vormindatud JavaScript sisu t\u00f6\u00f6tlemisel v\u00f5ib r\u00fcndaja k\u00e4ivitada s\u00fcsteemi taseme vabalt valitud koodi.<\/p>\n

Haavatavus esineb js2py globaalset muutuja implementatsioonis, mis v\u00f5imaldab p\u00e4\u00e4seda Python objekti viideti isoleeritud keskkonna JavaScripti koodist, vaatamata js2py.disable_pyimport() meetodi v\u00e4ljakutsele, et keelata Python objektide importimine. Vabalt valitud koodi k\u00e4ivitamiseks s\u00fcsteemis v\u00f5ib r\u00fcndaja kasutada haavatavust, et p\u00e4\u00e4seda Python alams\u00fcsteemi subprocess objekti Popen. T\u00e4helepanuv\u00e4\u00e4rne on, et haavatavuse likvideerimise muudetud versioon saadeti Js2Py projektile 1. m\u00e4rtsil, kuid kolme ja poole kuu jooksul ei ole seda vastu v\u00f5etud.
