The remote SUSE Linux SUSE15 host has packages installed that are affected by a vulnerability as referenced in the openSUSE-SU-2021:4208-1 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"The remote SUSE Linux SUSE15 host has packages installed that are affected by a vulnerability as referenced in the
openSUSE-SU-2021:4208-1 advisory.
- 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.
