| Third-party Component | CVE ID | Summary of Vulnerability | Reason why Product is not Vulnerable | Date Determined False Positive |
| Apache Log4J | CVE-2021-45105 | Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3 and 2.3.1) did not protect from uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed in Log4j 2.17.0, 2.12.3, and 2.3.1. | This vulnerability happens whenever a customized pattern layouts is used similar to the below: <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n ${${::-${::-$${::-j}}}}"/> <PatternLayout pattern=ā%d %p %c{1.} [%t] $${ctx:loginId} %m%nā/> SCG does not use customized pattern layouts with thread context variables as part of the layout. Also, no user input goes into thread context variables. As lookups are disabled in 2.16.0, the vulnerability is not applicable even if the thread context variables are passed as part of the message. OS attack which is identified in Log4j 2.16.0, does not have an impact on SCG. |

| Apache Log4J | CVE-2021-44832 | Apache Log4j2 versions 2.0-beta7 through 2.17.0 (excluding security fix releases 2.3.2 and 2.12.4) are vulnerable to a remote code execution (RCE) attack when a configuration uses a JDBC Appender with a JNDI LDAP data source URI when an attacker has control of the target LDAP server. This issue is fixed by limiting JNDI data source names to the java protocol in Log4j2 versions 2.17.1, 2.12.4, and 2.3.2. | In SCG and SAE, we do not use JDBCAppender. SCG uses only FileAppender to log in to the filesystem. The vulnerability is not applicable for SCG and SAE. |
