Vulnerability Data

openssl_encrypt versions before 1.4.0 contain an arbitrary code execution vulnerability in the Whirlpool hash implementation that uses broad glob patterns to load .so modules without integrity verification. Attackers can place malicious .so files matching the whirlpool*py313*.so pattern in site-packages directories…

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

CM-6 Configuration Settings good match

Secure baseline settings can enforce absolute, organization-controlled paths for critical resources.

CM-7 Least Functionality partial match

Least-functionality configuration can prohibit unapproved directories or executables from being reachable via search paths.

SA-8 Security and Privacy Engineering Principles partial match

Engineering principles such as trusted paths, complete mediation, and least privilege directly require hard-coded or validated search paths instead of external ones.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-01 partial match
blocks

Hardened configuration baselines can enforce safe search paths and restrict environment variables that enable the weakness.

PR.PS-05 partial match
blocks

Preventing execution of unauthorized code directly blocks the malicious binaries that an untrusted search path would load.

PR.PS-06 partial match
blocks

Secure development practices include avoiding or sanitizing externally influenced search paths in application code.
