Memory corruption via unchecked encryption parameter
Published Dec 15, 2023 · Updated Aug 2, 2024
Buffer overflow in Shenzhen Libituo LBT-T300-T310 firmware 2.2.2.6 allows remote attackers to corrupt memory. The /apply.cgi handler accepts an oversized ApCliEncrypType value without a length restriction and passes it through the wireless configuration call chain to makeCurRemoteApList. The published request supplies HTTP Basic credentials, and public evidence neither establishes whether authentication is required nor demonstrates code execution.
