Arena Input Analyzer: Improper Validation of Specified Quantity in Input
CVE-2024-6068 is a high-severity improper validation of specified quantity in input vulnerability in Arena Input Analyzer from Rockwell Automation, with a CVSS 3.1 base score of 7.3 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. Affected Arena Input Analyzer versions: <=16.20.03. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.25% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
