The affected element is the function sub_12580 of the file api.cgi of the component Login Processing. The manipulation of the argument REMOTE_ADDR leads to os command injection. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 2026-09-24-841a51c6d5_tclinux.bin is sufficient to fix this issue. You should upgrade the affected component. The vendor confirms: \"We confirm the finding, and it has already been addressed. In the current firmware the api=info&client=app handler no longer builds a shell command: the login script is now invoked through an argument vector (execvp) instead of system(), and the client address is length-limited and null-checked.\"","state":0,"publishedAt":"2026-10-15T14:45:15.76+00:00","modifiedAt":"2026-10-20T02:40:46.273+00:00","affected":[{"ecosystem":"Vendor product","name":"WL-WN530BE2-A","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Wavlink\",\n                    \"product\": \"WL-WN530BE2-A\",\n                    \"versions\": [\n                        {\n                            \"version\": \"M30BE2_V250604\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"2026-09-24-841a51c6d5_tclinux.bin\",\n                            \"status\": \"unaffected\"\n                        }\n                    ],\n                    \"cpes\": [\n                        \"cpe:2.3:a:wavlink:wl-wn530be2-a:*:*:*:*:*:*:*:*\"\n                    ],\n                    \"modules\": [\n                        \"Login Processing\"\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:P","score":10,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C","score":10,"severity":"CRITICAL"},{"system":"CVSS 3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C","score":10,"severity":"CRITICAL"},{"system":"CVSS 2.0","vector":"AV:N/AC:L/Au:N/C:C/I:C/A:C/E:POC/RL:OF/RC:C","score":10,"severity":null}],"references":["https://vuldb.com/vuln/420570","https://vuldb.com/vuln/420570/cti","https://vuldb.com/cve/CVE-2026-110957","https://vuldb.com/submit/920217","https://github.com/F-yyjy/cve/blob/main/WN530BE2-A_api-cgi.md","https://dl.wavlink.com/firmware/RD/WN530BE2_WAVLINK-WO-2026-09-24-841a51c6d5_tclinux.bin"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-110957","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-110957","identifiers":["CVE-2026-110957"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
