https://notcve.org/view.php?id=CVE-2021-3310
Western Digital My Cloud OS 5 devices before 5.10.122 mishandle Symbolic Link Following on SMB and AFP shares. This can lead to code execution and information disclosure (by reading local files). Los dispositivos Western Digital My Cloud OS 5 versiones anteriores a 5.10.122, manejan inapropiadamente recursos compartidos de Symbolic Link Following en SMB y AFP. Esto puede conllevar a una ejecución de código y divulgación de información (mediante la lectura de archivos locales) This vulnerability allows remote attackers to disclose sensitive information on affected installations of Western Digital MyCloud PR4100. Authentication is not required to exploit this vulnerability. The specific flaw exists within the SMB and AFP services. • https://github.com/piffd0s/CVE-2021-3310 https://www.westerndigital.com/support/productsecurity/wdc-21002-my-cloud-firmware-version-5-10-122 https://www.zerodayinitiative.com/advisories/ZDI-21-277 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
CVSS: 9.0EPSS: 1%CPEs: 18EXPL: 2CVE-2019-9949
https://notcve.org/view.php?id=CVE-2019-9949
Western Digital My Cloud Cloud, Mirror Gen2, EX2 Ultra, EX2100, EX4100, DL2100, DL4100, PR2100 and PR4100 before firmware 2.31.183 are affected by a code execution (as root, starting from a low-privilege user session) vulnerability. The cgi-bin/webfile_mgr.cgi file allows arbitrary file write by abusing symlinks. Specifically, this occurs by uploading a tar archive that contains a symbolic link, then uploading another archive that writes a file to the link using the "cgi_untar" command. Other commands might also be susceptible. Code can be executed because the "name" parameter passed to the cgi_unzip command is not sanitized. • https://bnbdr.github.io/posts/wd https://community.wd.com/t/new-release-my-cloud-firmware-versions-2-31-183-05-20-2019/237717 https://github.com/bnbdr/wd-rce • CWE-59: Improper Link Resolution Before File Access ('Link Following') •

Western Digital My Cloud, My Cloud Mirror Gen2, My Cloud EX2 Ultra, My Cloud EX2100, My Cloud EX4100, My Cloud DL2100, My Cloud DL4100, My Cloud PR2100 and My Cloud PR4100 firmware before 2.31.174 is affected by an authentication bypass vulnerability. The login_mgr.cgi file checks credentials against /etc/shadow. However, the "nobody" account (which can be used to access the control panel API as a low-privilege logged-in user) has a default empty password, allowing an attacker to modify the My Cloud EX2 Ultra web page source code and obtain access to the My Cloud as a non-Admin My Cloud device user. My Digital, My Cloud Mirror Gen2, My Cloud EX2 Ultra, My Cloud EX2100, My Cloud EX4100, My Cloud DL2100, My Cloud DL4100, My Cloud PR2100 y My Cloud PR4100 firmware anterior a 2.31.174, se ve impactado por una vulnerabilidad de omisión de autenticación . El archivo login_mgr.cgi verifica las credenciales contra /etc/shadow. • https://bnbdr.github.io/posts/wd https://community.wd.com/t/new-release-my-cloud-firmware-versions-2-31-174-3-26-19/235932 https://github.com/bnbdr/wd-rce https://support.wdc.com/downloads.aspx?g=2702&lang=en • CWE-521: Weak Password Requirements •
