Der er blevet offentliggjort korrigerende versioner af Log4j-biblioteket 2.17.1, 2.3.2-rc1 og 2.12.4-rc1, hvori der er blevet udbedret endnu en s\u00e5rbarhed (CVE-2021-44832). Det n\u00e6vnes, at problemet muligg\u00f8r udf\u00f8relse af kode p\u00e5 afstand (RCE), men det er samtidig markeret som ikke farligt (CVSS Score 6.6) og repr\u00e6senterer prim\u00e6rt kun teoretisk interesse, da det kr\u00e6ver specifikke betingelser for udnyttelse \u2014 angriberen skal have mulighed for at \u00e6ndre konfigurationsfilen for Log4j, dvs. de skal have adgang til det angrebne system og bef\u00f8jelser til at \u00e6ndre v\u00e6rdien af parameteren log4j2.configurationFile eller foretage \u00e6ndringer i eksisterende logningskonfigurationsfiler. <\/p>\n

Angrebet g\u00e5r ud p\u00e5 at bestemme konfigurationen p\u00e5 det lokale system baseret p\u00e5 JDBC Appender, der henviser til en ekstern JNDI URI, ved foresp\u00f8rgsel af hvilken der kan blive returneret en Java-klasse til udf\u00f8relse. Som standard er JDBC Appender ikke konfigureret til at behandle protokoller andre end Java, dvs. uden \u00e6ndringer i konfigurationen er angrebet umuligt. Desuden optr\u00e6der problemet kun i JAR-filen log4j-core og p\u00e5virker ikke applikationer, der bruger JAR-filen log4j-api uden log4j-core. \t ...
