Hazard

Is CVE-2016-3088 being exploited?

Weaponised and widely attempted

Reliable public exploit code exists, or mass exploitation attempts are probable. Patch inside days, not weeks.

Apache ActiveMQ Improper Input Validation Vulnerability

Apache · ActiveMQ

CVSS 9.8 EPSS 99% 2 public exploits Fix deadline passed 10 August 2022

What it is

The Fileserver web application in Apache ActiveMQ allows remote attackers to upload and execute arbitrary files via an HTTP PUT followed by an HTTP MOVE request

Why we say that

  • EPSS puts exploitation in the next 30 days at 99%
  • 2 public exploits published
  • CISA's federal remediation deadline (2022-08-10) has passed
  • CVSS 9.8 critical
  • Listed in the CISA Known Exploited Vulnerabilities catalogue

Every line above comes from a named public source. Where the evidence is thin, we say so rather than inventing confidence — see methodology.

What to do

Apply updates per vendor instructions.

Public exploit code

Indexed from Exploit-DB. Presence of code raises urgency; absence does not mean safety.

What it costs when this goes wrong
