ATT&CK techniques
No public source states how this vulnerability is exploited in ATT&CK terms.
The only authoritative CVE → ATT&CK mapping in the open — CTID's Mappings Explorer, pinned to a KEV snapshot of 2025-07-28 and ATT&CK 16.1 — does not include CVE-2025-20362. This entry was added to KEV on 2025-09-25, after that snapshot; of the 283 entries added since, 0 have a mapping. CISA's catalogue carries no technique field. kevmap does not infer techniques from the CWE (CWE-862) — here is why — and does not guess.
This page will change state automatically if a mapping is published. What is shown above is everything CISA publishes about the entry.
Sigma rules tagged with this CVE
1 rule in SigmaHQ carries the tag cve.2025-20362. These are shown as detection content for the CVE itself. Their ATT&CK tags are deliberately not rendered here: a rule author's tag is not an authoritative statement of how the vulnerability is exploited, and this page does not show techniques for unmapped entries.
