Mark, I think I see your problem as being something different than Pete or BKBK suggested (though there may well be value for you in what they offer, of course).1) You said, "In the directory E:/cfusion/lib/updates/, I have all of the corresonding chf20210016.jar for each update."Er, if you really mean what you're saying (you have ALL the chf jar files for EACH update in that folder), that's a problem (and indeed could be THE problem with your failing scans). 2) To be clear, the CF update mechanism would never put multiple chf*.jar files there. It would only ever leave in there the chf*.jar file of whatever update you last applied. (Besides a tool like Tenable, CF itself could be confused terribly by there being multiple chf*.jar files, given how Java classloading works.)3) So did you do that yourself? Perhaps you're working offline and felt you needed to "do things manually". (Even then, the technotes for each update discuss manual offline updates, and they do NOT suggest doing what you did.)Or perhaps you read about doing it somewhere (in which case, please let us know so that we can suggest to the author that they elaborate on their motivation for thi ssuggestion).4) And I suspect your teneble scanning may be simply looking AT that lib/updates folder, and if it somehow "finds first" one that is BELOW the version that it expects for whatever sec vuln it's assessing, that would be why it would complain (with what I'm sure seems a confusing message...but I don't think they ever fathomed that people would have more than one chf*.jar in that lib/updates folder, so don't intelligently identify and recommend how to solve that problem.)Indeed, I'll say I'd never heard of anyone doing it before. So if this is indeed what you did, it's a good thing to get out in the open here, in case someone else may trip over it. 5) Finally in removing the extra chf*.jar files, note that if you find any hf*.jar files in that lib/updates folder, consider carefully whether you should "just remove" those also. They may be "needed" for you.Such an hf*.jar file is "patch" file (or "hotfix", whereas the chf*.jar files are "cumulative hotfix" files--which is what CF updates put in place). These hf/hotfix/patch files are sometimes offered by Adobe as something that changes CF behavior that is NOT in offered in an "update". Such is the. How do I open a jar file in Minecraft Java?
