Description

A security flaw has been discovered in TRENDnet TEW-432BRP 3.10B20. This affects the function formSetPortTr of the file /goform/formSetPortTr. Performing a manipulation of the argument special_name results in stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been released to the public and may be used for attacks. The vendor explains: "This product has been EOL for 15 years (since 2009). As the item has been EOL for such a long time, we are not able to replicate or fix any vulnerabilities." This vulnerability only affects products that are no longer supported by the maintainer.

• CWE-119Improper Restriction of Operations within the Bounds of a Memory BufferThe product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
• CWE-121Stack-based Buffer OverflowA stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
