Korrigierte Versionen der Log4j-Bibliothek 2.17.1, 2.3.2-rc1 und 2.12.4-rc1 wurden ver\u00f6ffentlicht, in denen eine weitere Schwachstelle (CVE-2021-44832) behoben wurde. Es wird erw\u00e4hnt, dass das Problem die M\u00f6glichkeit eines Remote Code Execution (RCE) erm\u00f6glicht, jedoch als nicht kritisch eingestuft wird (CVSS Score 6.6) und haupts\u00e4chlich von theoretischem Interesse ist, da es spezifische Bedingungen f\u00fcr die Ausnutzung erfordert \u2013 der Angreifer muss in der Lage sein, \u00c4nderungen an der Log4j-Konfigurationsdatei vorzunehmen, das hei\u00dft, er muss Zugang zum angegriffenen System haben und die Berechtigung, den Wert des Konfigurationsparameters log4j2.configurationFile zu \u00e4ndern oder \u00c4nderungen an bestehenden Protokolldateien vorzunehmen. <\/p>\n

Der Angriff besteht darin, die Konfiguration der lokalen Umgebung zu bestimmen, die auf einer JDBC-Appender basiert, die auf eine externe JNDI-URI verweist, von der ein Java-Klasse zum Ausf\u00fchren zur\u00fcckgegeben werden kann. Standardm\u00e4\u00dfig ist der JDBC-Appender nicht f\u00fcr die Verarbeitung anderer Protokolle als Java konfiguriert, das hei\u00dft, ohne Konfigurations\u00e4nderungen ist ein Angriff nicht m\u00f6glich. Dar\u00fcber hinaus tritt das Problem nur in der JAR-Datei log4j-core auf und betrifft keine Anwendungen, die die JAR-Datei log4j-api ohne log4j-core verwenden. \t \u2026
