Summary

CVE-2024-21852 is a high-severity Path Traversal (CWE-22) vulnerability in Rapidscada Rapid Scada. Its CVSS base score is 8.8 (High).

Operationally, ranked in the top 21.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis

Rapid SCADA versions prior to 5.8.4 contain a Zip Slip vulnerability (CWE-22) in the configuration file unpacking routine. An attacker can supply a malicious archive that performs path traversal during extraction, resulting in arbitrary file writes that enable remote code execution. The flaw carries a CVSS 3.1 score of 8.8 with network attack vector, low complexity, and low privileges required.

An authenticated remote attacker can upload the crafted configuration archive over the network and achieve full compromise of confidentiality, integrity, and availability on the affected SCADA system. No user interaction is needed once the malicious file is processed by the unpacking routine.

CISA advisory ICSA-24-011-03 and vendor guidance direct users to upgrade to Rapid SCADA 5.8.4 or later. The EPSS score rose from a low baseline to a peak of 0.1525 on 2025-01-22 before receding to the current 0.0115, indicating a period of increased exploitation interest after disclosure.
