A vulnerability was found in Buffalo WSR-3200AX4S, WSR-3200AX4B, WSR-2533DHP, WSR-2533DHP2, WSR-A2533DHP2, WSR-2533DHP3, WSR-A2533DHP3, WSR-2533DHPL, WSR-2533DHPL2, WSR-2533DHPLS and WCR-1166DS and classified as critical. This issue affects an unknown code block of the component CTI Program. The manipulation with an unknown input leads to a os command injection vulnerability. Using CWE to declare the problem leads to CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Buffalo network devices WSR-3200AX4S firmware Ver. 1.26 and earlier, WSR-3200AX4B firmware Ver. 1.25, WSR-2533DHP2 firmware Ver. 1.22 and earlier, WSR-A2533DHP2 firmware Ver. 1.22 and earlier, WSR-2533DHP3 firmware Ver. 1.26 and earlier, WSR-A2533DHP3 firmware Ver. 1.26 and earlier, WSR-2533DHPL2 firmware Ver. 1.03 and earlier, WSR-2533DHPLS firmware Ver. 1.07 and earlier, WEX-1800AX4 firmware Ver. 1.13 and earlier, and WEX-1800AX4EA firmware Ver. 1.13 and earlier allows a network-adjacent attacker with an administrative privilege to execute an arbitrary OS command if a specially crafted request is sent to a specific CGI program.

The weakness was released 12/19/2022. The advisory is shared at jvn.jp. The identification of this vulnerability is CVE-2022-43466 since 12/05/2022. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1202 for this issue.
