Published: 28 August 2022
Summary
CVE-2022-37053 is a critical-severity Code Injection (CWE-94) vulnerability in Trendnet Tew733Gr Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 4.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CVE-2022-37053 is a command injection vulnerability in the TRENDnet TEW733GR router running firmware version 1.03B01. The flaw resides in the /htdocs/upnpinc/gena.php component and is classified under CWE-94, allowing improper control over code generation. It carries a CVSS 3.1 base score of 9.8, reflecting network attack vector, low complexity, and no required authentication or user interaction.
An unauthenticated attacker with network access can supply crafted input to the affected UPnP GENA endpoint and execute arbitrary operating-system commands. Successful exploitation yields full read, write, and control over the device, enabling actions such as configuration changes, credential theft, or persistent compromise.
Public references consist of the vendor domain and a shared technical document; no official patch or mitigation guidance is detailed in the available sources. The EPSS score has remained flat at 0.1841 since disclosure, indicating steady but not increasing exploitation interest.

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.
