7DescriptionCVE.org
A vulnerability was found in Tenda HG10 300001138. This vulnerability affects the function formURL of the file /boaform/admin/formURL. Performing a manipulation of the argument Keywd/urlFQDN results in buffer overflow. The attack may be initiated remotely. The exploit has been made public and could be used.
AnalysisAI
Remote unauthenticated buffer overflow in Tenda HG10 firmware 300001138 allows network attackers to corrupt memory and likely achieve code execution via the formURL function at /boaform/admin/formURL. Oversized values in the Keywd or urlFQDN parameters are copied into a fixed-size buffer without length validation (CWE-120), with full confidentiality, integrity, and availability impact per the CVSS 4.0 vector. …
