CVE-2018-25024Network attack vector

Memory corruption via unsound mutable-reference coercion

Published Dec 26, 2021 · Updated Aug 5, 2024

Memory corruption in Actix actix-web before 0.7.19 allows remote attackers to corrupt process memory through unsafe reference aliasing. The crate unsoundly turns an immutable reference into a mutable reference, violating Rust aliasing guarantees, but the affected API is undisclosed. RustSec identifies use-after-free as the most likely corruption scenario; public sources do not document the exact request trigger or resulting control over the server process.
