The Zyxel NAS is potentially affected by multiple vulnerabilities.
- This command injection vulnerability in the 'setCookie' parameter in Zyxel NAS326 and NAS542 devices could allow an unauthenticated attacker to execute some OS commands by sending a crafted HTTP POST request. (CVE-2024-29973)
- This remote code execution vulnerability in the CGI program 'file_upload-cgi' in Zyxel NAS326 and NAS542 devices could allow an unauthenticated attacker to execute arbitrary code by uploading a crafted configuration file to a vulnerable device. (CVE-2024-29974)
- This improper privilege management vulnerability in the SUID executable binary in Zyxel NAS326 and NAS542 devices could allow an authenticated local attacker with administrator privileges to execute some system commands as the βrootβ user on a vulnerable device. (CVE-2024-29975)
Note that Nessus has not tested for this issue but has instead relied only on the applicationβs self-reported model number.
