What to do

Workaround (from the CVE record)

To mitigate this issue, ensure sticky-directory symlink protections are enabled on your system. This can be done immediately by running `sysctl -w fs.protected_symlinks=1`. To make this change persistent across reboots, create or modify a file in `/etc/sysctl.d/` (e.g., `/etc/sysctl.d/99-sysctl.conf`) with the content `fs.protected_symlinks=1` and then run `sysctl --system`. Additionally, avoid running the `sblim-cmpi-base` provider registration scripts from shared multi-user systems where untrusted users can create symlinks in `/tmp` or `/var/tmp`. If manual execution of the script is necessary, prefer using a private, root-owned temporary directory.

About this vulnerability

A flaw was found in sblim-cmpi-base. Insecure temporary file creation in the provider registration scripts allows a local unprivileged user to perform a symlink attack. By creating a symlink in a world-writable directory, an attacker can redirect privileged writes to an arbitrary file during script execution in a privileged context. This can lead to the overwrite of root-owned files, potentially…

Description

Sblim-cmpi-base: insecure temporary file creation in sblim-cmpi-base provider registration scripts allows local symlink attack

A flaw was found in sblim-cmpi-base. Insecure temporary file creation in the provider registration scripts allows a local unprivileged user to perform a symlink attack. By creating a symlink in a world-writable directory, an attacker can redirect privileged writes to an arbitrary file during script execution in a privileged context. This can lead to the overwrite of root-owned files, potentially disrupting system services or operation. Exploitation is conditional on the script running with elevated privileges and may be mitigated by sticky-directory symlink protections.
