| CVE-2020-29529 | 1 Hashicorp | 1 Go-slug | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| HashiCorp go-slug up to 0.4.3 did not fully protect against directory traversal while unpacking tar archives, and protections could be bypassed with specific constructions of multiple symlinks. Fixed in 0.5.0. | |||||
| CVE-2020-28935 | 2 Debian, Nlnetlabs | 3 Debian Linux, Name Server Daemon, Unbound | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| NLnet Labs Unbound, up to and including version 1.12.0, and NLnet Labs NSD, up to and including version 4.3.3, contain a local vulnerability that would allow for a local symlink attack. When writing the PID file, Unbound and NSD create the file if it is not there, or open an existing file for writing. In case the file was already present, they would follow symlinks if the file happened to be a symlink instead of a regular file. An additional chown of the file would then take place after it was written, making the user Unbound/NSD is supposed to run as the new owner of the file. If an attacker has local access to the user Unbound/NSD runs as, she could create a symlink in place of the PID file pointing to a file that she would like to erase. If then Unbound/NSD is killed and the PID file is not cleared, upon restarting with root privileges, Unbound/NSD will rewrite any file pointed at by the symlink. This is a local vulnerability that could create a Denial of Service of the system Unbound/NSD is running on. It requires an attacker having access to the limited permission user Unbound/NSD runs as and point through the symlink to a critical file on the system. | |||||

| CVE-2020-27833 | 1 Redhat | 1 Openshift Container Platform | 2024-11-21 | 4.6 MEDIUM | 7.1 HIGH |
| A Zip Slip vulnerability was found in the oc binary in openshift-clients where an arbitrary file write is achieved by using a specially crafted raw container image (.tar file) which contains symbolic links. The vulnerability is limited to the command `oc image extract`. If a symbolic link is first created pointing within the tarball, this allows further symbolic links to bypass the existing path check. This flaw allows the tarball to create links outside the tarball's parent directory, allowing for executables or configuration files to be overwritten, resulting in arbitrary code execution. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Versions up to and including openshift-clients-4.7.0-202104250659.p0.git.95881af are affected. | |||||

| CVE-2020-27643 | 1 1e | 1 Client | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
| The %PROGRAMDATA%\1E\Client directory in 1E Client 5.0.0.745 and 4.1.0.267 allows remote authenticated users and local users to create and modify files in protected directories (where they would not normally have access to create or modify files) via the creation of a junction point to a system directory. This leads to partial privilege escalation. | |||||
| CVE-2020-27172 | 1 Gdatasoftware | 1 G Data | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| An issue was discovered in G-Data before 25.5.9.25 using Symbolic links, it is possible to abuse the infected-file restore mechanism to achieve arbitrary write that leads to elevation of privileges. | |||||
| CVE-2020-26277 | 1 Dbdeployer | 1 Dbdeployer | 2024-11-21 | 4.0 MEDIUM | 6.1 MEDIUM |
| 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. | |||||
