CVE-2013-0422

CriticalCVSS 9.8KEV
Published: Translated: NVD NIST

Summary

Wielokrotne podatności w Oracle Java 7 przed aktualizacją 11 pozwalają zdalnym atakującym na wykonanie dowolnego kodu. Wykorzystują one metodę getMBeanInstantiator w klasie JmxMBeanServer oraz API refleksji, co umożliwia obejście zabezpieczeń.

Risk Assessment

Organizacje mogą być narażone na zdalne ataki, które mogą prowadzić do przejęcia kontroli nad systemami, co stwarza poważne zagrożenie dla bezpieczeństwa danych.

Recommendation

Zaleca się aktualizację Oracle Java do najnowszej wersji, aby usunąć te podatności oraz wdrożenie dodatkowych środków zabezpieczających, takich jak monitorowanie i ograniczenie dostępu do krytycznych systemów.

Original NVD description (English source)

Multiple vulnerabilities in Oracle Java 7 before Update 11 allow remote attackers to execute arbitrary code by (1) using the public getMBeanInstantiator method in the JmxMBeanServer class to obtain a reference to a private MBeanInstantiator object, then retrieving arbitrary Class references using the findClass method, and (2) using the Reflection API with recursion in a way that bypasses a security check by the java.lang.invoke.MethodHandles.Lookup.checkSecurityManager method due to the inability of the sun.reflect.Reflection.getCallerClass method to skip frames related to the new reflection API, as exploited in the wild in January 2013, as demonstrated by Blackhole and Nuclear Pack, and a different vulnerability than CVE-2012-4681 and CVE-2012-3174. NOTE: some parties have mapped the recursive Reflection API issue to CVE-2012-3174, but CVE-2012-3174 is for a different vulnerability whose details are not public as of 20130114. CVE-2013-0422 covers both the JMX/MBean and Reflection API issues. NOTE: it was originally reported that Java 6 was also vulnerable, but the reporter has retracted this claim, stating that Java 6 is not exploitable because the relevant code is called in a way that does not bypass security checks. NOTE: as of 20130114, a reliable third party has claimed that the findClass/MBeanInstantiator vector was not fixed in Oracle Java 7 Update 11. If there is still a vulnerable condition, then a separate CVE identifier might be created for the unfixed issue.
