CVE-2020-26277 Information

Description

DBdeployer is a tool that deploys MySQL database servers easily. In DBdeployer before version 1.58.2 users unpacking a tarball may use a maliciously packaged tarball that contains symlinks to files external to the target. In such scenario an attacker could induce dbdeployer to write into a system file thus altering the computer defenses. For the attack to succeed the following factors need to contribute: 1) The user is logged in as root. While dbdeployer is usable as root it was designed to run as unprivileged user. 2) The user has taken a tarball from a non secure source without testing the checksum. When the tarball is retrieved through dbdeployer the checksum is compared before attempting to unpack. This has been fixed in version 1.58.2.
