CVE-2021-4045: TP-LINK Tapo C200 remote code execution vulnerability

Noroxi assessment

Priority: This week (action score 61/100)

  • Public proof-of-concept code exists (Exploit-DB, GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 72.3% (FIRST EPSS); higher than 99.4% 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. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

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.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

TP-Link Tapo C200 IP camera, on its 1.1.15 firmware version and below, is affected by an unauthenticated RCE vulnerability, present in the uhttpd binary running by default as root. The exploitation of this vulnerability allows an attacker to take full control of the camera.
