CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:HSummary
CVE-2024-32487 is a high-severity Static Code Injection (CWE-96) vulnerability in Greenwoodsoftware Less. Its CVSS base score is 8.6 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Content Injection (T1659); ranked at the 47th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Vulnerability Data
less through 653 allows OS command execution via a newline character in the name of a file, because quoting is mishandled in filename.c. Exploitation typically requires use with attacker-controlled file names, such as the files extracted from an untrusted archive.…

Exploitation also requires the LESSOPEN environment variable, but this is set by default in many common cases.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing neutralization of directives in saved code artifacts.
Input validation directly stops unneutralized directives from being inserted into static code resources.
Engineering principles include secure input handling and neutralization requirements that structurally avoid static injection.

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.
Secure SDLC practices directly require input neutralization to block static code injection into templates, configs, or libraries.

Security testing in development and acceptance will detect static code injection but does not prevent it at the source.
Secure development life cycle mandates input validation and sanitization that directly prevents static code injection.
Application security requirements include rules for neutralizing untrusted input before it is stored in executable resources.
Secure architecture principles reduce injection surfaces but do not prescribe the specific neutralization techniques.
Secure coding explicitly requires proper neutralization of directives in templates, libraries and configuration files.
Change management can catch unsafe code changes but does not enforce input neutralization.
