Vulnerability details
A vulnerability was found in TRENDnet TEW-432BRP 3.10B20. This impacts the function formSetDomainFilter of the file /goform/formSetDomainFilter. Performing a manipulation of the argument blocked_domain/permitted_domain/blocked_domain_list/permitted_domain_list results in stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has…

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Ongoing control assessments and code testing (static/dynamic analysis, fuzzing) surface memory buffer restriction failures, which are then remediated before release.
Managed runtimes used by platform-independent applications (e.g., JVM, CLR) enforce memory safety, preventing most buffer overflows that require direct memory manipulation.
Memory protections (e.g., W^X, ASLR) make exploitation of buffer-boundary violations far harder to turn into code execution.
Detects exploitation attempts that produce memory corruption, crashes, or anomalous behavior.
