Analysis
🔴 Critical — actively exploited
Weakness: Integer Overflow (CWE-190). A calculation overflows and corrupts sizes or memory.
How it's exploited: Exploitable over the network (internet-reachable), unauthenticated, no user interaction, and with low complexity. The flaw can pivot to other components (scope changed).
⚠️ Critical combo: remote, unauthenticated and no interaction → trivial to automate.
Impact: Full compromise (confidentiality, integrity and availability).
Status: Active exploitation confirmed by CISA (KEV).
- Patch now: it is in CISA's actively-exploited catalog (KEV), with a deadline.
- Reduce exposure: keep it off the internet; firewall, VPN or network segmentation.
- Detect: turn this CVE into detection rules.
