TITLE

plural Western Digital My Cloud Link interpretation vulnerabilities in products

Trust: 0.8

sources: JVNDB: JVNDB-2019-004912

DESCRIPTION

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. plural Western Digital My Cloud The product contains a link interpretation vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Western Digital MyCloud Mirror Gen 2 and others are products of Western Digital Corporation. WesternDigitalMyCloudMirrorGen2 is a personal cloud storage device. WesternDigitalMyCloudEX2Ultra is a personal cloud storage device. The Western Digital MyCloud EX2100 is a personal storage device. A security vulnerability exists in several WesternDigital products that originated from the failure of the program to filter the \342\200\230name\342\200\231 parameter passed to the cgi_unzip command. An attacker could exploit the vulnerability to execute code
