CVE-2022-26925: Windows LSA Spoofing Vulnerability

Noroxi assessment

Priority: This week (action score 60/100)

CISA has confirmed exploitation in the wild (Jul 1, 2022). Remediation deadline for US federal agencies: Jul 22, 2022.
A ready-made attack tool exists and the flaw can be exploited over the network without an account, so priority is at least “This week”.
Probability of exploitation in the next 30 days: 10.4% (FIRST EPSS); higher than 95.7% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
According to CISA the attack is automatable: targets can be found by mass scanning.
According to the record, no fixed version is available yet.
Severity is disputed: the assigning authority (CNA) scores it 8.1, NVD 5.9.
Mentioned 3 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Don’t wait for the next maintenance window. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.
