IEC 1Ph 7.4kW Child socket: Initialization of a Resource with an Insecure Default
CVE-2025-31930 is a high-severity initialization of a resource with an insecure default vulnerability in IEC 1Ph 7.4kW Child socket from Siemens, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited from the same local network by an unauthenticated attacker, without any action from a user. The record lists version V2.135 as the first without the flaw, so updating IEC 1Ph 7.4kW Child socket to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.29% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update IEC 1Ph 7.4kW Child socket to V2.135 or a later version.
- Update IEC 1Ph 7.4kW Child socket/ shutter to V2.135 or a later version.
- Update IEC 1Ph 7.4kW Parent cable 7m to V2.135 or a later version.
