Security readout for executives and security teams
Plain-English summary
This CVE describes a remotely reachable buffer overflow in a Tenda i22 firmware function. The published CVSS score is high because an unauthenticated network attacker could trigger a crash or denial of service without user interaction. The sources do not name a vendor patch or confirm real-world exploitation.
Executive priority
Treat this as high priority where Tenda i22 devices support business connectivity or segmented wireless access. The main business risk is service disruption, not confirmed data theft. Prioritize exposure reduction while checking vendor guidance.
Technical view
CVE-2022-45664 is a CWE-120 buffer overflow in Tenda i22 V1.0.0.3(4687), involving the list parameter in formwrlSSIDget. The CVSS 3.1 vector is AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H, indicating availability impact only. Official affected CPE metadata is incomplete.
Likely exposure
Exposure is most likely on Tenda i22 devices running V1.0.0.3(4687), especially if their web or management interface is reachable from untrusted networks. The CVE metadata does not provide complete affected-product enumeration.
Exploitation context
The source bundle does not show CISA KEV listing or other evidence of active exploitation. Public vulnerability details are referenced on GitHub, but no cited source here establishes exploitation in the wild.
Researcher notes
The key evidence is the CVE description, CVSS vector, CWE-120 classification, and a public GitHub reference. Affected product metadata is sparse, and no patch, workaround, or exploitation evidence is provided in the supplied sources.
Mitigation direction
- Inventory Tenda i22 devices and identify firmware V1.0.0.3(4687).
- Remove device management interfaces from internet exposure.
- Restrict access to trusted administrator networks only.
- Check Tenda guidance for firmware updates or official workarounds.
- Replace or isolate devices if no supported fix is available.
Validation and detection
- Confirm whether any deployed device matches Tenda i22 V1.0.0.3(4687).
- Review firewall rules for exposed router or access-point management services.
- Verify remote administration is disabled from untrusted networks.
- Monitor affected devices for unexpected crashes, reboots, or service loss.
- Track vendor and CVE records for updated affected-version or fix data.
