Advisory Summary

Western Digital My Cloud Web App uses a weak SSLContext when attempting to configure port forwarding rules. This was enabled to maintain compatibility with old or outdated home routers. As a result, a local user with least privileges can exploit this vulnerability and jeopardize the integrity, confidentiality and authenticity of information transmitted. This vulnerability was resolved by enabling TLS ConnectionSwitching to a "TLS" context instead of "SSL".

CVE Number: CVE-2022-23000

Addressed multiple libtiff null pointer dereference vulnerabilities by updating the version to 4.4.0. 

CVE Number:  CVE-2022-0562,  CVE-2022-0561,  CVE-2022-0865

Addressed an improper input validation and out-of-bounds write vulnerability in TensorFlow which is an open-source platform for machine learning. An attacker could pass negative values to cause a segmentation fault-based denial-of-service attack. Certain components also did not validate input arguments which could also trigger a denial-of-service attack.

CVE Number:  CVE-2022-29191,  CVE-2022-29213,  CVE-2022-29208

Addressed multiple FFmpeg vulnerabilities by updating the version to 7:4.1.9-0+deb10u1.

Western Digital My Cloud devices were vulnerable to a cross-site scripting vulnerability that could allow an attacker with elevated privileges to access drives being backed up, to construct and inject JavaScript payloads into an authenticated user's browser. As a result, it may be possible to gain control over the authenticated session, steal data, modify settings, or redirect the user to malicious websites. This was resolved by output sanitization.
