Question 830
A scanner reports a critical flaw based solely on an HTTP banner with a potentially spoofed version. Which evidence most strongly validates the intended interpretation or control?
Explanation
Correct Answer
The finding contains trustworthy version proof or is downgraded as unconfirmed. This answer directly addresses the described constraint. Banner-only matching can produce false positives. Successful validation requires: The finding contains trustworthy version proof or is downgraded as unconfirmed.
Incorrect Answers
It would address a scanner detects a self-signed certificate on a test-only internal service. The relevant reason in that case is: A self-signed certificate can be appropriate in controlled trust contexts. Here the required success condition is the finding contains trustworthy version proof or is downgraded as unconfirmed. The relevant evidence is: The finding contains trustworthy version proof or is downgraded as unconfirmed.
That approach concerns a different situation: a host reports UDP ports as open-or-filtered and the analyst marks them definitely exploitable. Silence does not prove a UDP listener exists. The required result is that the finding contains trustworthy version proof or is downgraded as unconfirmed. The relevant evidence is: The finding contains trustworthy version proof or is downgraded as unconfirmed.
That relates to a different issue: A vulnerability ID references a flaw fixed in a backported enterprise Linux package. Vendor backports can remediate CVEs without changing upstream major version. That is not a direct remedy for the requested outcome: The finding contains trustworthy version proof or is downgraded as unconfirmed. The relevant evidence is: The finding contains trustworthy version proof or is downgraded as unconfirmed.
