This section reads the record's references and adds cited findings from outside it. It needs an account. Everything above is held facts and is complete without it.
What would change this brief held, dated
- CISA KEV
- Not listed in the catalogue we hold. A listing changes this brief.
- exploit probability
- 0.01 on 2026-09-01 (FIRST's EPSS, a probability and not evidence of exploitation). Next band line: 10% (0.10). Crossing a line changes this brief.
- fix
- Held: scalance x302-7eec firmware 4.1.4; scalance x304-2fe firmware 4.1.4; scalance x306-1ldfe firmware 4.1.4; scalance x307-2eec firmware 4.1.4; scalance x307-3 firmware 4.1.4…. A newer fix from the CNA or OSV changes this brief.
How to check this
Every value above is held with two dates: when it was true upstream (as_of) and when we recorded it (tx_from). Re-derive the exploit probability as it stood on any date:
SELECT value, source, source_version, as_of, tx_from
FROM volatile_valid_as_of('CVE-2022-25751', '2026-10-30T23:59:59.999999Z', now());
