Summary of what we know so far:
- The vulnerability CVE-2021-44228 affects log4j 2.x only. It was introduced in version 2.0-beta9 and fixed in 2.15.0-rc2. log4j 1.x is unaffected. For the vulnerability to be present, log4j-core-2.*.jar (or a shaded equivalent) needs to be bundled with the plugin, anything else (slf4j bridges, API jars, log4j 1.x) doesn't include the vulnerable class (see below).
- Recent JREs prohibit the specific LDAP RCE exploit, but other exploits exist (e.g. capturing env vars).
- Maven Shade Plugin may rename packages, so there may be matches in other packages (but a patched usage-in-plugins found none in latest plugin releases)
- Further plugins may have included the library in older releases. We are working on a list.
- log4j 2.16.0 includes a fix for another security vulnerability, see https://lists.apache.org/thread/83y7dx5xvn3h5290q1twn16tltolv88f It's low severity, and requires a nondefault configuration to be exploitable (or attackers able to configure logging). It affects 2.0-beta9 through 2.15.0 (inclusive) and is fixed in 2.16.0.
- The specific affected classes are org.apache.logging.log4j.core.lookup.JndiLookup and org.apache.logging.log4j.core.net.JndiManager (previously org.apache.logging.log4j.core.appender.JndiManager). The former should be removed manually according to https://logging.apache.org/log4j/2.x/security.html when using affected versions. This applied to both vulnerabilities.
