CVE-2024-41985 is a high-severity vulnerability in SmartClient modules Opcenter QL Home (SC) from Siemens, with a CVSS 3.1 base score of 7.3 out of 10. It can be exploited from the same local network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version V2506 as the first without the flaw, so updating SmartClient modules Opcenter QL Home (SC) to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.2% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
