CVE-2025-45857
Published: 13 May 2025
Summary
CVE-2025-45857 is a critical-severity Code Injection (CWE-94) vulnerability in Edimax Cv-7428Ns Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 10.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
EDIMAX CV7428NS firmware version 1.20 contains a remote code execution vulnerability in the mp function, where an attacker can supply arbitrary input through the command parameter. The flaw is tracked as CVE-2025-45857 with a CVSS 3.1 base score of 9.8 and is classified under CWE-94 for improper control of code generation.
Because the vulnerability is reachable over the network without authentication or user interaction, an unauthenticated remote attacker can execute operating-system commands on the device, resulting in full confidentiality, integrity, and availability impact.
Public references consist of a technical write-up and proof-of-concept hosted on GitHub together with the vendor’s site; neither source describes an available firmware patch or configuration workaround at the time of disclosure. The associated EPSS score has remained flat at 0.0440 with no observed upward trajectory since publication.

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.
