A successful exploit could allow the attacker to interrupt all traffic flowing through the affected device. A sustained attack could cause an out of memory condition on the affected device. An attacker could exploit this vulnerability by sending a series of crafted IP packets that would generate specific Snort events on an affected device. This vulnerability is due to insufficient memory management for certain Snort events. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects.Ģ3 Firepower 1000, Firepower 1010, Firepower 1020 and 20 moreĪ vulnerability in the Snort detection engine integration for Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause unlimited memory consumption, which could lead to a denial of service (DoS) condition on an affected device. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), this functionality has been completely removed. From log4j 2.15.0, this behavior has been disabled by default. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. 156 Log4j, Synchro, Synchro 4d and 153 moreĪpache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints.
