"value": "Improper input validation vulnerability in Apache ActiveMQ, Apache ActiveMQ KahaDB.\n\n\n\nThe ActiveMQ broker resolves connection, session and consumer state from ids that are user provided and in some scenarios does not validate that they ids are bound to that user. This allows an authenticated client to spoof another user\u0027s ids. This allows:\n\n\n\n\n\n * \u00a0an authenticated client consumes from another connection\u0027s temporary queue/topic by putting the victim\u0027s connection id in its own ConsumerId, bypassing the broker-side ownership check.\u00a0\n * a duplicate ConsumerId registration is only logged, after which the attacker\u0027s RemoveInfo or disconnect tears down the victim\u0027s live subscription\n * a forged MessageAck for the victim\u0027s ConsumerId permanently deletes an in-flight, unacknowledged message.\n\n\n\n\n\n\n\n\nThis issue affects Apache ActiveMQ: from 6.0.0 before 6.3.3, before 5.19.12; Apache ActiveMQ KahaDB: from 6.0.0 before 6.3.3, before 5.19.12.\n\n\n\nUsers are recommended to upgrade to version 6.4.0, 6.3.3, or 5.19.12, which fixes the issue."

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
