Hardcoded AES Key in Acer Wave 7 upload.cgi Backup Processing
CVE-2026-49201 is a hardcoded cryptographic key vulnerability affecting Acer Wave 7 mesh routers running firmware T7c_GBL_1.01.000055 and earlier. The vulnerable component is the upload.cgi binary, which processes device backups and contains a static hardcoded AES encryption key. Because the key is embedded in the binary, an attacker can use it to decrypt protected backup files, alter their contents, and re-encrypt them into a form accepted by the device. This breaks the intended confidentiality and integrity protections of the backup mechanism and enables malicious modification of backup data, including insertion of persistent backdoor content that can be restored onto the router.
