CVE-2025-69257
Unknown Unknown - Not Provided
Arbitrary Code Execution via Unsafe Config in theshit Utility

Publication date: 2025-12-30

Last updated on: 2025-12-30

Assigner: GitHub, Inc.

Description
theshit is a command-line utility that automatically detects and fixes common mistakes in shell commands. Prior to version 0.1.1, the application loads custom Python rules and configuration files from user-writable locations (e.g., `~/.config/theshit/`) without validating ownership or permissions when executed with elevated privileges. If the tool is invoked with `sudo` or otherwise runs with an effective UID of root, it continues to trust configuration files originating from the unprivileged user's environment. This allows a local attacker to inject arbitrary Python code via a malicious rule or configuration file, which is then executed with root privileges. Any system where this tool is executed with elevated privileges is affected. In environments where the tool is permitted to run via `sudo` without a password (`NOPASSWD`), a local unprivileged user can escalate privileges to root without additional interaction. The issue has been fixed in version 0.1.1. The patch introduces strict ownership and permission checks for all configuration files and custom rules. The application now enforces that rules are only loaded if they are owned by the effective user executing the tool. When executed with elevated privileges (`EUID=0`), the application refuses to load any files that are not owned by root or that are writable by non-root users. When executed as a non-root user, it similarly refuses to load rules owned by other users. This prevents both vertical and horizontal privilege escalation via execution of untrusted code. If upgrading is not possible, users should avoid executing the application with `sudo` or as the root user. As a temporary mitigation, ensure that directories containing custom rules and configuration files are owned by root and are not writable by non-root users. Administrators may also audit existing custom rules before running the tool with elevated privileges.

Can you explain this vulnerability to me?

This vulnerability exists in the Rust package "theshit" prior to version 0.1.1. The application loads custom Python rules and configuration files from user-writable locations without validating ownership or permissions when run with elevated privileges (e.g., via sudo). This allows a local attacker to inject arbitrary Python code through malicious rules or configuration files, which then execute with root privileges, enabling privilege escalation from an unprivileged user to root. The issue arises because the tool trusts configuration files from the unprivileged user's environment even when running as root. The vulnerability was fixed in version 0.1.1 by enforcing strict ownership and permission checks on these files to prevent execution of untrusted code. [2, 1]


How can this vulnerability impact me? :

If you run the "theshit" tool with elevated privileges, this vulnerability allows a local unprivileged user to escalate their privileges to root by injecting malicious Python code via configuration or rule files. This can lead to arbitrary code execution with root privileges, compromising system confidentiality, integrity, and availability. In environments where the tool is allowed to run with passwordless sudo, an attacker can gain root access without additional interaction. Systems running vulnerable versions and executing the tool as root or via sudo are at risk. [2]


How can this vulnerability be detected on my network or system? Can you suggest some commands?

To detect this vulnerability on your system, you should audit the ownership and permissions of the configuration directories and Python rule files used by theshit, especially those in user-writable locations like ~/.config/theshit/. You can use commands such as `ls -l ~/.config/theshit/` to check file ownership and permissions. Additionally, verify if the tool is being executed with elevated privileges (e.g., via sudo) by checking sudoers configurations or process executions. There is no specific network detection method since this is a local privilege escalation vulnerability. The key is to identify improperly owned or writable configuration files that could be exploited. [2]


What immediate steps should I take to mitigate this vulnerability?

Immediate mitigation steps include: 1) Avoid running the theshit utility with sudo or as the root user if upgrading is not possible. 2) Ensure that directories containing custom rules and configuration files (e.g., ~/.config/theshit/) are owned by root and are not writable by non-root users. 3) Audit existing custom rules and configuration files for proper ownership and permissions before running the tool with elevated privileges. 4) Upgrade theshit to version 0.1.1 or later, which includes strict ownership and permission checks preventing this vulnerability. [2]


How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:

This vulnerability allows local privilege escalation and arbitrary code execution with root privileges, which can lead to unauthorized access and modification of sensitive data. Such unauthorized access and potential data breaches can negatively impact compliance with standards and regulations like GDPR and HIPAA, which require strict controls on data confidentiality, integrity, and access management. Organizations using the affected tool without the fix may face increased risk of non-compliance due to insufficient privilege management and access controls. [2]
