Grails web-raamistikus, mis on m\u00f5eldud veebirakenduste arendamiseks MVC paradigma j\u00e4rgi Java, Groovy ja teiste JVM-i keeltega, on avastatud haavatavus, mis v\u00f5imaldab kaugel k\u00e4ivitada oma koodi keskkonnas, kus veebirakendus t\u00f6\u00f6tab. Haavatavuse \u00e4rakasutamine toimub spetsiaalselt vormindatud p\u00e4ringu saatmise kaudu, mis annab r\u00fcndajale ligip\u00e4\u00e4su ClassLoaderile. Probleem tuleneb andmete sidumise (data-binding) loogika puuduj\u00e4\u00e4gist, mida kasutatakse nii objektide loomisel kui ka k\u00e4sitsi sidumisel bindData abil. Probleem on lahendatud versioonides 3.3.15, 4.1.1, 5.1.9 ja 5.2.1. <\/p>\n

Lisaks v\u00f5ib mainida, et Ruby mooduli tzinfo haavatavus v\u00f5imaldab laadida mis tahes faili sisu, s\u00f5ltuvalt r\u00fcnnatava rakenduse \u00f5igustest. Haavatavus tuleneb piisava kontrolli puudumisest erim\u00e4rkide kasutamise osas ajav\u00f6\u00f6ndi nime m\u00e4\u00e4ramisel, mis antakse meetodile TZInfo::Timezone.get. Probleem puudutab rakendusi, mis edastavad TZInfo::Timezone.get'ile kontrollimata v\u00e4lised andmed. N\u00e4iteks faili \/tmp\/payload lugemiseks v\u00f5ib m\u00e4\u00e4rata v\u00e4\u00e4rtuse, mis n\u00e4eb v\u00e4lja nagu «foo\n\/..\/..\/..\/tmp\/payload».
