Summary

CVE-2023-29804 is a high-severity OS Command Injection (CWE-78) vulnerability in Iodata Wfs-Sr03W Firmware. Its CVSS base score is 8.8 (High).

Operationally, ranked in the top 4.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

WFS-SR03 version 1.0.3 contains a command injection vulnerability, tracked as CVE-2023-29804 and assigned CWE-78, that resides in the sys_smb_pwdmod function. The flaw received a CVSS 3.1 base score of 8.8, reflecting network attack vector, low attack complexity, and low required privileges.

An authenticated attacker with low privileges can supply crafted input to the affected function over the network and execute arbitrary operating-system commands, resulting in full compromise of confidentiality, integrity, and availability on the device. No user interaction is required.

Public references consist of a Notion disclosure page that details the command-injection vector but contain no information on vendor patches or configuration mitigations. The associated EPSS score rose from lower values to a peak of 0.4723 before receding to the current 0.1991, indicating a period of increased exploitation interest after disclosure.
