Vulnerability Type:T08: Insecure Dependencies
Risk Level: MediumVulnerable Code
markdown Before running the script, ensure the following Python libraries are installed: ```bash pip install pandas numpy lightgbm yfinancetext ### Technical Analysis The documented installation command retrieves mutable latest versions of four third-party packages and their transitive dependencies. No version constraints, cryptographic hashes, lockfile, or trusted package-index configuration are provided. Consequently, the reviewed source does not uniquely determine the code that users will install and execute. A malicious or compromised package release, transitive dependency, or configured Python package index could supply attacker-controlled code. Python packages may execute code during installation through build backends, and their modules execute code when imported by `condor_signals.py`. This finding does not establish that the named packages are currently malicious. It identifies an avoidable supply-chain exposure caused by installing unverified, unpinned artifacts. ### Attack Path 1. An attacker compromises a named package, one of its transitive dependencies, or a package index used by the victim. 2. The attacker publishes or serves an artifact containing malicious installation or import-time code. 3. A user follows the instructions and runs: ```bash pip install pandas numpy lightgbm yfinance- Because versions and hashes are not constrained,
pipresolves and downloads the attacker-controlled artifact. - Malicious code executes during package build or installation, or when
condor_signals.pyimports the installed module. - The payload operates with the permissions and environment access of the user running the installation or script.

Remediation Suggestions
- Define reviewed, exact dependency versions in a requirements or lock file rather than installing unconstrained latest releases.
- Generate and verify cryptographic hashes for every direct and transitive artifact. For example, use a fully resolved requirements file with:
bash python -m pip install --require-hashes -r requirements.txt - Commit the lock file to source control and update dependencies through a controlled review process.
- Document and enforce an approved HTTPS package index; disable untrusted extra indexes to reduce dependency-confusion exposure.
- Install dependencies in a dedicated virtual environment or isolated container under a non-privileged account. Do not run
pipas root or with administrative privileges. - Scan locked dependencies for known vulnerabilities and review dependency updates before adoption.
- Consider using an internal artifact repository that stores vetted packages and preserves approved versions.
