Summary

CVE-2024-34218 is a low-severity Command Injection (CWE-77) vulnerability in Totolink Cp450 Firmware. Its CVSS base score is 3.8 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 8.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

TOTOLINK outdoor CPE CP450 version 4.1.0cu.747_B20191224 contains a command injection vulnerability (CWE-77) in the NTPSyncWithHost function. The flaw is triggered through the hostTime parameter and received a CVSS 3.1 score of 3.8, reflecting network attack vector, low complexity, and the requirement for high privileges.

An authenticated administrator with network access can supply a crafted hostTime value to inject and execute operating-system commands on the device. Successful exploitation yields limited impacts on confidentiality and integrity while leaving availability unaffected.

Public references consist of proof-of-concept material hosted in a GitHub repository that demonstrates the injection vector; no vendor advisory or patch information is included in the available references.

The associated EPSS score reached a peak of 0.0902 after disclosure before settling at the current value of 0.0662, indicating a measurable increase in exploitation interest following publication.
