CVE-2023-2912Network attack vector

Unauthenticated service interruption via use-after-free

Published Jul 17, 2023 · Updated Oct 22, 2024

Use-after-free in Secomea SiteManager Embedded before 11.0 allows remote attackers to interrupt the gateway service via network requests. Secomea has not disclosed the affected code path or the memory-lifetime error that causes a freed object to be reused. Exploitation requires no privileges or user interaction but has high complexity; the documented consequence is availability loss only.
