HighCVSS 8.8 · v3.1—No exploit No fix recorded

Noroxi assessment

Priority: Monitor (action score 36/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.8% (FIRST EPSS); higher than 79% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

A stack-based buffer overflow vulnerability exists in the web interface Radio Scheduling functionality of Tp-Link AC1350 Wireless MU-MIMO Gigabit Access Point (EAP225 V3) v5.1.0 Build 20220926. A specially crafted series of HTTP requests can lead to remote code execution. An attacker can make an authenticated HTTP request to trigger this vulnerability.This vulnerability refers specifically to the overflow that occurs via the `band` parameter at offset `0x422420` of the `httpd` binary shipped with v5.0.4 Build 20220216 of the EAP115.
