SkySwimmer opened a new pull request #633:
URL: https://github.com/apache/logging-log4j2/pull/633
I have completely removed JNDI from the Interpolator, so that the
CVE-2021-44228 exploit will not be able to call LDAP.
```java
// Interpolator.java (org.apache.logging.log4j.core.lookup.Interpolator)
// ...
strLookupMap.put("base64", new Base64StrLookup());
strLookupMap.put("lower", new LowerLookup());
strLookupMap.put("upper", new UpperLookup());
- // JNDI
- if (JndiManager.isJndiEnabled()) {
- try {
- // [LOG4J2-703] We might be on Android
- strLookupMap.put(LOOKUP_KEY_JNDI,
-
Loader.newCheckedInstanceOf("org.apache.logging.log4j.core.lookup.JndiLookup",
StrLookup.class));
- } catch (final LinkageError | Exception e) {
- handleError(LOOKUP_KEY_JNDI, e);
- }
- }
// ...
```
I hope this helps.
