CVE-2024-32487 is a high-severity OS command injection vulnerability in the 'less' utility (versions prior to 653), affecting Debian, Greenwood Software, and NetApp products. It allows an attacker to execute arbitrary commands by crafting a malicious filename containing a newline character, which is mishandled during quoting. Exploitation requires user interaction (e.g., opening a malicious file from an untrusted archive) and the LESSOPEN environment variable, which is often set by default. There is currently no evidence of active exploitation, public exploit code, or significant community discussion, and it is not listed in CISA's KEV catalog.

CVE-2024-32487
Jul 9, 2024less: OS command injection
Apr 13, 2024less 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.
