# CVE-2025-59374: ASUS Live Update Embedded Malicious Code Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run ASUS Live Update. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2025-12-17, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2026-01-07 ; treat that as the outer limit, not the target.
- EPSS 1.2% , percentile 68: FIRST’s model estimates a 1.2% chance of exploitation activity in the next 30 days, higher than 68% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.

## What it is

"UNSUPPORTED WHEN ASSIGNED" Certain versions of the ASUS Live Update client were distributed with unauthorized modifications introduced through a supply chain compromise. The modified builds could cause devices meeting specific targeting conditions to perform unintended actions. Only devices that met these conditions and installed the compromised versions were affected. The Live Update client has already reached End-of-Support (EOS) in October 2021, and no currently supported devices or products are affected by this issue.

## Affected products (CVE record)

- ASUS live update: before 3.6.6

## Severity

- ASUS CVSS 4.0: 9.3 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N`

## Exploitation

- CISA KEV: added 2025-12-17; federal due date 2026-01-07. Known ransomware use: Unknown.
- CISA required action: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
- CISA SSVC assessment: exploitation active , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 1.20% probability of exploitation activity in the next 30 days; percentile 68.
