SDM600: Origin Validation Error
CVE-2024-2377 is a high-severity origin validation error vulnerability in SDM600 from Hitachi Energy, with a CVSS 3.1 base score of 7.6 out of 10. It can be exploited from the same local network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. The record lists version 1.3.4 as the first without the flaw, so updating SDM600 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.21% 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 SDM600 to 1.3.4 or a later version.
- Update sdm600 to 1.3.4.572 or a later version.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
