Understanding The Results
_VULNERABLE_ - > You really want to redesign or eliminate this record.
_OKAY_ - > We just report this for Log4J form 2.15.0. We prescribe moving up to 2.16.0.
_SAFE_ - > We at present just report this for Log4J adaptations 2.16.0 and 2.12.2.
_OLD_ - > You are protected from CVE-2021-44228, however should plan to update in light of the fact that Log4J 1.2.x has been EOL for a considerable length of time and has a few known-weaknesses.
_POTENTIALLY_SAFE_ - > The "JndiLookup.class" document is absent, either on the grounds that your form of Log4J is extremely old (pre 2.0-beta9), or on the grounds that somebody previously eliminated this record. Ensure it was somebody in your group or organization that eliminated "JndiLookup.class" assuming that is the situation, since assailants have been known to eliminate this document themselves to keep extra contending aggressors from accessing compromised frameworks.
