Exploitation Probability (EPSS)

Low risk
0.31%

21th percentile - higher than 21% of all known CVEs

Summary

A file-transfer interface that requires valid credentials accepts attacker-controlled filenames without restricting shell metacharacters. An automated process later constructs and runs a system command using the uploaded file's name, allowing an authenticated attacker to embed and execute arbitrary operating system commands with the privileges of that process.

Risk Assessment

An attacker can read and modify ingested log data and could gain a foothold for further movement within the internal network. This poses a serious remote code execution risk.

Recommendation

Sanitize uploaded filenames and do not pass them directly to system commands — use safe APIs. Update the file processing pipeline to eliminate shell metacharacters.
