CVE-2024-33212

Memory corruption via unbounded funcpara1 processing

Published Apr 23, 2024 · Updated Aug 16, 2024

Stack-based buffer overflow in Tenda FH1206 1.2.0.8(8155)_EN allows remote attackers to corrupt memory via a crafted HTTP request. The setcfm handler fails to bound the funcpara1 parameter before writing it into stack storage. Unauthenticated access from an adjacent network is sufficient to reach the vulnerable handler and corrupt its process memory.
