Published: 11 September 2024
Summary
CVE-2024-44466 is a critical-severity Command Injection (CWE-77) vulnerability in Comfast Cf-Xr11 Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Unix Shell (T1059.004); ranked in the top 2.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
COMFAST CF-XR11 version 2.7.2 contains a command injection vulnerability in function sub_424CB4 that allows arbitrary commands to be executed through the iface parameter. The flaw is reachable by sending crafted POST requests to the /usr/bin/webmgnt endpoint and is tracked under CWE-77 and CWE-94 with a CVSS 3.1 score of 9.8.
An unauthenticated remote attacker can exploit the issue over the network to achieve full control of the device, including arbitrary code execution with impacts to confidentiality, integrity, and availability. No authentication or user interaction is required.
A public proof-of-concept is available in the referenced GitHub repository. The current EPSS score of 0.3895 matches its recorded peak, indicating sustained exploitation interest since disclosure. No vendor advisory or patch information is provided in the available references.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
